OPINION
DAVIS, Circuit Judge:
Appellants Nancy Bell and Iris Gibson (Bell’s daughter)
pled guilty without a plea agreement to several counts arising
out of a conspiracy to distribute oxycodone pills. On appeal,
they challenge the drug quantities from which the district
court calculated their base offense levels under the Sentencing
Guidelines, primarily because (1) Bell obtained the pills with
a valid prescription and consumed some of the pills herself,
and (2) the evidence of actual drug trafficking consisted of co-
conspirator testimony of uncertain reliability. Having fully
considered the parties’ contentions, we are persuaded that,
because the district court failed to explain adequately its
methodology for calculating drug quantity and otherwise to
UNITED STATES v. BELL 3
make findings sufficient to permit appellate review of Appel-
lants’ sentences for procedural reasonableness, we must
vacate the judgments and remand for resentencing.
I.
A.
At least since 2002, Bell, who is sixty-five years old, has
suffered from several back ailments, including sacroiliitis
(inflammation of the joints between the spine and pelvis),
lumbar radiculitis (inflammation of lumbar nerve roots), and
a protrusion of one of her lumbar discs. She also suffers from
occasional breakouts of shingles. Since 2002 she has received
treatment for the pain resulting from those ailments at the
Pain Management Center at St. Mary’s Medical Center in
Knoxville, Tennessee. Doctors at St. Mary’s have prescribed
Bell several narcotic pain relievers over the years, including
OxyContin for "long-acting relief" and Percocet for "break-
through pain." J.A. 276. At issue here is the OxyContin, a
brand name version of oxycodone, the distribution of which
in certain circumstances is unlawful.1
Beginning in or before January 2004 through April 2006,
Bell was prescribed ninety 20-mg OxyContin tablets per
month. In May 2006 her prescription was changed from 20-
mg to 40-mg pills, at first sixty pills per month and then,
beginning in June 2006, ninety pills per month. She continued
to be prescribed ninety 40-mg OxyContin pills per month
through August 2009.2 Because oxycodone is a controlled
1
Bell also suffers from atherosclerotic heart disease, insulin-dependent
diabetes, severe asthma and other conditions. Those conditions do not
appear to have been part of the reason Bell was prescribed pain medica-
tions. They were, however, relevant at sentencing, and led the district
court to recommend that her term of imprisonment be served at a federal
medical facility.
2
In fact she continued to receive oxycodone prescriptions after August
2009, but the probation officer used that date as the cut-off for calculating
drug quantity in this case.
4 UNITED STATES v. BELL
substance, she was required to undergo periodic "urine
screens" and "pill counts" to ensure she was consuming the
drug. J.A. 276. There is evidence in the record of several
urine screens, the results of most of which were "satisfactory"
or "appropriate," indicating that Bell was consuming at least
some of the oxycodone. One urine screen described in the
record, sometime prior to May 2004, was "low." All her pill
counts have been accurate. Indeed, her nurse at St. Mary’s
wrote that Bell "has an outstanding record with our pain cen-
ter." Id.
It turns out, though, that Bell was not consuming all of the
oxycodone pills she was prescribed. Instead, she was selling
a substantial number of them unlawfully and using much of
the money she received to buy lottery tickets. Specifically, as
the evidence at sentencing showed, twice a month Bell would
travel from her home in Marnardsville, Tennessee, to Jones-
ville, in Lee County, Virginia, where Gibson lived and where
they would either sell oxycodone pills for cash or front the
pills to others who would sell them and return to Bell or Gib-
son with the proceeds.
Law enforcement eventually learned of the scheme and
used a confidential informant to make three controlled pur-
chases from Bell and Gibson at Gibson’s residence in Lee
County, buying a total of ten 40-mg oxycodone pills. Officers
then obtained a search warrant for Gibson’s home, a trailer in
the Horton subdivision of Lee County, and executed the war-
rant on July 30, 2009. Agents found a pill bottle for OxyCon-
tin in Bell’s name with fifteen 40-mg OxyContin tablets and
thirteen Endocet tablets (a combination of acetaminophen and
oxycodone), and $1,776 in cash. They found two more 40-mg
OxyContin pills and five more Endocet pills in Bell’s purse,
which was in Gibson’s residence at the time of the search.
Five months later, on December 16, 2009, a federal grand
jury returned an indictment charging Bell, Gibson and six oth-
ers with conspiracy to possess with intent to distribute oxyco-
UNITED STATES v. BELL 5
done from January 1, 2004 to December 14, 2009, in violation
of 21 U.S.C. §§ 846 and 841(b)(1)(C). Bell and Gibson were
also charged with three counts of distributing oxycodone in
violation of 21 U.S.C. §§ 841(a)(1) and 841(b)(1)(C), and one
count of maintaining or using a drug house in violation of 21
U.S.C. § 856(a)(1) between June 1, 2009 and July 30, 2009.
They were arrested on December 22, 2009, and each was
released on bond.
In due course, Gibson pled guilty to each count of the
indictment without a plea agreement, followed by Bell shortly
thereafter.
B.
In anticipation of sentencing, pre-sentence reports ("PSRs")
were prepared for Bell and Gibson. The principal consider-
ation in calculating the base offense level under the Sentenc-
ing Guidelines was the quantity of drugs attributable to the
conspiracy. To determine that number, the probation officer
relied primarily on the prescriptions through which Bell
received her oxycodone pills. As stated above, from January
2004 to April 2006 (27 months) Bell received ninety 20-mg
pills per month, a total of 2,430 pills with a total weight of
48.6 grams. In May 2006 she received sixty 40-mg pills, with
a total weight of 2.4 grams. From June 2006 to August 2009
(38 months) she received ninety 40-mg pills per month, a total
of 3,420 pills with a total weight of 136.8 grams. The total
weight of all the oxycodone pills Bell was prescribed from
January 2004 to August 2009 was 187.8 grams, equivalent to
4,695 40-mg pills.
Under the Sentencing Guidelines, 1 gram of oxycodone is
designated as equivalent to 6,700 grams of marijuana for sen-
tencing purposes. U.S.S.G. § 2D1.1, cmt. n.10(E) (2009).
Thus during the period of the conspiracy as alleged, Bell was
prescribed and received the oxycodone equivalent of 1,258.26
kilograms of marijuana. This number yielded a base offense
6 UNITED STATES v. BELL
level of 32, the level that applies to marijuana weights
between 1,000 and 3,000 kilograms. See id. § 2D1.1(c)(4).
The probation officer recommended a three-point upward
adjustment for Bell’s role in the offense and a three-point
downward adjustment for acceptance of responsibility, result-
ing in a total offense level of 32. With a criminal history cate-
gory of I, the advisory range for a term of imprisonment was
87 to 108 months.
The probation officer noted in the PSR that Bell may have
been distributing some pills other than those prescribed to her,
namely pills prescribed to her husband, William Bell. She and
William separated in 1992 but, according to the PSR, "remain
good friends." J.A. 495. The probation officer did not con-
sider these pills in calculating drug weight, however, because,
although "agents suspect[e]d" the defendants were also selling
pills prescribed to William, the government could not "prove
this theory." J.A. 491.
The Appellants objected to the drug weight calculation in
the PSR on several grounds. Principally, Bell argued the gov-
ernment could not prove she distributed or intended to distrib-
ute all the pills prescribed to her because her medical records
showed that she was taking a "significant amount" of the oxy-
codone that had been prescribed. J.A. 120. She also argued
that any testimony from the conspiracy’s largest buyers, Kim
Smith and Tim Pace, should be disregarded because of irrec-
oncilable inconsistencies in their statements to investigators.
Finally, Bell argued that the government could not prove that
she distributed any pills prescribed to William Bell; the only
pills the court should consider, therefore, were those pre-
scribed to her. Given these constraints, the Appellants calcu-
lated the total number of pills distributed by the conspiracy as
888 40-mg pills, or 35.52 grams, equivalent to 238 kilograms
of marijuana. Because Bell did not object to the three-level
increase for her role in the offense, this weight would yield
base and total offense levels of 26 and an advisory imprison-
ment term of 63 to 78 months.
UNITED STATES v. BELL 7
Bell also urged the court to depart downward from the
Guidelines and impose probation instead of a term of impris-
onment because of her age and many health problems.
C.
At the sentencing hearing the government sought to estab-
lish the quantity of drugs attributable to the conspiracy in two
ways: (1) through documentation of the pills prescribed to
Bell, and (2) through the testimony of co-conspirators who
purchased drugs from Bell and Gibson. The theory was that
the prescriptions proved the conspiracy’s supply, and the wit-
nesses’ testimony demonstrated that Bell and Gibson sold to
co-conspirators a sizeable portion of the pills prescribed to
Bell.
The Appellants did not dispute that from January 2004 to
August 2009 Bell was prescribed and received 2,430 20-mg
oxycodone pills and 3,420 40-mg pills. They did dispute,
however, whether they agreed to posses with intent to distrib-
ute or to distribute all of those pills. As stated above, their
position was that the government could only prove they sold
888 40-mg pills during the course of the conspiracy, and
therefore could only prove that they conspired to possess with
intent to distribute that quantity.
Six co-conspirators testified at the sentencing hearing.
Because the testimony of these witnesses figures prominently
in the issues presented, we set forth the testimony in some
detail.
The largest sales were to the first two witnesses, Kimberly
Smith, a relative of Bell through marriage, and her fiancé
Timothy Pace, who were each long-time oxycodone addicts.
On direct examination, Smith testified that from July 2005 to
January 2007 she received 30 to 60 40-mg oxycodone tablets
from Bell twice a month. At first she was just buying pills for
herself; after a "couple [of] months" she began selling some
8 UNITED STATES v. BELL
of the pills she acquired from Bell to others in order to make
money to buy pills for herself. J.A. 325. On cross-
examination, however, she admitted that before May 2006 she
received 20-mg pills, not 40-mg pills, and that she had suppli-
ers other than Bell, although she did not know their names.
She admitted that sometimes Gibson was absent when she
purchased pills from Bell.
Pace largely corroborated this testimony, though he put the
twice-monthly range he and Kim received "to sell" from mid-
2005 through 2006 at 30 to 50 40-mg pills. He also admitted
that sometimes he and Smith did not buy from Bell but rather
from other suppliers. When asked by the government whether
he was "selling OxyContin with anybody else" or rather was
"acting on [his] own" he replied, "No, it was me and my fian-
cée." J.A. 346. When asked whether he and Kim would "sell
pills together or . . . split them up" he replied, "No, we was
together." J.A. 349. On cross-examination he also explained
that, either included in or in addition to the 30 to 50 pills
twice a month they received "to sell," he and Kim received 12
to 20 pills "or a little less" twice a month for their own use.
He also testified that he saw pill bottles with William Bell’s
name on them, prescribed for 90 40-mg pills per month.
The next two witnesses were a married couple, Joyce and
Timothy Hopkins, also both long-time addicts. Joyce testified
that in early 2007 she bought two oxycodone pills from Gib-
son, possibly continuing twice per month. Six to eight months
later she was buying 5 to 10 40-mg pills and later 10 to 15 40-
mg pills twice per month. At first she purchased pills from
Gibson; in late 2007 she purchased pills from Bell. On cross-
examination, she admitted to sometimes receiving 80-mg oxy-
codone pills from another supplier. She continued to buy pills
until she was arrested in March 2009.
Timothy testified that he and Joyce did not begin buying
oxycodone pills from Bell until "two and a half years . . . or
so" before the sentencing hearing, which would be the winter
UNITED STATES v. BELL 9
of 2007-2008, J.A. 384; this was inconsistent with Joyce’s
testimony that they first purchased from Bell in early 2007.
His testimony as to the monthly amounts was that he and
Joyce started buying no more than 10 40-mg pills and later
increased to 10 to 15 40-mg pills, but apparently just once
(not twice) per month. Although the government encouraged
him to testify that he received 20 pills per month, he insisted
it was "[t]en, 15, something like that." J.A. 386. He also testi-
fied that some months he did not have money to buy any pills.
J.A. 390. He stopped buying pills from the defendants in
March 2009, when he was arrested. The testimony is unclear
as to whether he and Joyce were buying together and thus
were referring to the same pills.
The government’s fifth witness, Leslie Clasby, testified that
she bought oxycodone from Bell for four months, from Octo-
ber 2008 until sometime between January and March 2009.
She would purchase up to 20 40-mg pills during a month but
"[s]ometimes not that many." J.A. 394, 397. When the district
court asked her to clarify, she said that for four months or
"possibly longer" she purchased up to 20 pills per month. J.A.
396. But on cross-examination she admitted that there were
times Bell was not available and so she purchased from
another supplier. She also could not recall whether Bell was
available around Christmas 2008.
The government’s sixth witness was Misty Parker, Gib-
son’s daughter (and Bell’s granddaughter) who was twenty-
two years old at the time of sentencing and had lived in a
group home or foster home beginning at age 14 because her
mother was deemed unfit to supervise her. According to Par-
ker, "just about everybody in my family has a drug problem."
J.A. 399. Beginning sometime in June or July 2008 she began
receiving 10 to 15 pills twice a month from Bell. Although at
first she resold the full amount, she soon "started using" and
by August had been kicked out of Gibson’s home because of
her drug use. J.A. 403. She went to a rehabilitation program
for a month during May to June 2009, but began using again
10 UNITED STATES v. BELL
after she was released. She continued to receive pills from
Bell until Bell’s arrest in July 2009. For an unspecified period
of time she sold some of her pills to Leslie Clasby and possi-
bly to Joyce Hopkins.
Parker described her grandmother as a "a very sick
woman," someone who was like a "walking pharmacy"
because of all the medications she needed for her heart prob-
lems, diabetes, blood pressure and other illnesses. J.A. 408.
According to Parker, Bell was not addicted to drugs, but she
was addicted to gambling by buying lottery tickets, and sold
oxycodone pills to support her gambling habit.
The witnesses testified that many of their purchases of oxy-
codone were made at Gibson’s home, in a trailer park in
Jonesville in the Horton Subdivision of Lee County, where
Bell would stay when she visited twice a month. But other
sales were made elsewhere. For example, sometimes Smith
and Bell would drive to Smith’s customers’ homes. Smith
would go up to the residence and find out how many pills the
customer wanted and the customer would give Smith money
for the pills. Smith would then return to the car and give some
or all of the money to Bell, Bell would give Smith the pills,
and Smith would deliver the pills to the customer.
Thus, to summarize the witnesses’ testimony as to the
amounts distributed by Bell and Gibson: (1) No one testified
to buying pills earlier than July 2005 or later than July 2009.3
(2) Pills received from Bell and Gibson before May 2006
were probably 20-mg pills; those received during or after May
2006 were probably 40-mg pills. (3) Smith and Pace received
somewhere between 24 and 120 pills per month from July
2005 to January 2007 at the latest and likely were referring to
the same pills (i.e., buying together). (4) Joyce Hopkins began

The indictment charged that the conspiracy existed from on or about
January 1, 2004, until on or about December 14, 2009, although the search
warrant was executed at Gibson’s residence in July 2009.
UNITED STATES v. BELL 11
buying two pills per month in early 2007 (though possibly late
2007), eventually increasing to 10 to 15 pills twice per month,
until her arrest in March 2009. (5) Timothy Hopkins bought
10 to 15 pills per month from late 2007 or early 2008 until
March 2009 and likely bought together with Joyce and thus
was referring to the same pills. (6) Clasby bought up to 20
pills per month between January and March 2009. (7) Parker
bought 10 to 15 pills twice a month from June or July 2008
until July 2009, interrupted by one month in a rehabilitation
program. She sold some of her drugs to Clasby, and possibly
some to Joyce Hopkins.
D.
After the witnesses’ testimony, counsel presented argu-
ments on the proper Guidelines calculation. The defendants
objected to the drug weight calculation, pointing to the evi-
dence that Bell was consuming some of the pills: her positive
urine screen, her frequent proper pill counts, and the letter
from the St. Mary’s pain center that her record there was "out-
standing." Because the evidence of Bell’s supply (i.e., her pre-
scriptions) was not an accurate indicator of the amount
distributed (or, by implication, the amount Bell agreed to pos-
sess to distribute), they argued, the court had to rely solely on
the testimony at sentencing, and this testimony only proved
by a preponderance that the defendants conspired to possess
with intent to distribute a total of 80 20-mg pills and 180 40-
mg pills, even less than the 888 40-mg pills the defendants
had previously conceded in their written submissions the gov-
ernment could prove. The marijuana equivalent of that num-
ber of pills would be 58.96 kg, with a base offense level of
20 and an advisory range of 41 to 51 months imprisonment.
Gibson further argued that, whatever the total drug weight
attributable to Bell, that weight should be decreased for Gib-
son because the evidence showed that Gibson participated in
the conspiracy only beginning in May 2008. Gibson provided
documentary evidence that her lease for a particular lot in a
12 UNITED STATES v. BELL
trailer park in Jonesville did not begin until May 2008. She
also provided a letter showing that she was on a lease for a
different home, an apartment on Chappel Drive in Jonesville,
beginning in May 2004, although the "renewal paperwork" in
2006 for that apartment did not include Gibson’s name. There
was no documentary evidence, however, of where Gibson
lived in the two to three years before May 2008. Based on the
May 2008 lease, and because the witnesses "all agreed that
the activities . . . Gibson was participating in, occurred on or
after a period of time that she lived there at the trailer park,"
Gibson argued, the district court should reject the co-
conspirators’ testimony insofar as they testified that Gibson
and/or Bell sold drugs from Gibson’s trailer in Jonesville
prior to May 2008. J.A. 417. In other words, Gibson did not
dispute that she helped sell drugs from her trailer, but argued
that only those drugs sold in or after May 2008, a period of
eleven to thirteen months, should be attributed to her.
For its part, the government sought strenuously to under-
mine all of the Appellants’ contentions. First, the government
dismissed the argument that Bell might have herself con-
sumed some of the pills prescribed to her. "Even if Ms. Bell
is taking some of the pills," the government argued, "one
motivation, [if] not the over reaching [sic] motivation, for get-
ting these OxyContins was to distribute them." J.A. 420.
Moreover, the government contended, "even if a defendant is
using or consuming drugs, that . . . drug weight might be attri-
buted to him, or her." Id. Thus, the government argued, "the
court should consider [Bell’s] prescription records as an accu-
rate or conservative drug weight amount in this case." Id.
Those records yield a conservative estimate, the government
argued, because of the evidence that she was also selling pills
prescribed to her husband, William. Second, the government
argued that the full amount attributable to the conspiracy
should be attributed to Gibson, not just drugs obtained and
distributed in or after May 2008.
After considering the parties’ contentions, the district court
stated its conclusions under the Guidelines. First, the court
UNITED STATES v. BELL 13
rejected the Appellants’ argument in support of a deduction
from the prescribed amount for those drugs that Bell herself
may have consumed, stating: "Where a drug conspiracy is
involved, drugs obtained by the defendant for her personal use
are properly included in the quantity of drugs that the defen-
dant knew were distributed by the conspiracy." J.A. 424. With
respect to the witnesses’ testimony, the court "credit[ed] their
testimony in regard to the quantity of drugs." J.A. 425. The
court then concluded that "the upper level of their testimony
concerning quantity of drugs is the proper amount to accept
by a preponderance of the evidence, and I do that because it
is corroborated by the quantity of drugs prescribed to the
defendant, Bell." J.A. 425-26.
The district court did not then proceed to calculate the
amounts prescribed to Bell. Nor did the court state the number
of pills the government established by a preponderance of the
evidence had been distributed or possessed with the intent to
distribute. The court did acknowledge that "[t]here are obvi-
ously some discrepancies in the testimony of witnesses based
on a lack of memory," but concluded those discrepancies
were "not material." J.A. 427. Nevertheless, the court then
stated, "I will partially sustain the objection of the defendant
[Bell]," and concluded, "[B]ased on my acceptance of the tes-
timony of these persons I find that the defendant Bell was
responsible for distribution of at least 700 kilograms equiva-
lency of marijuana." J.A. 426.
Although the court did not recite how it reached 700 kilo-
grams, under the Guidelines 1 gram of oxycodone is equiva-
lent to 6,700 grams of marijuana, and so the 700 kilogram
marijuana-equivalency finding means that the court held Bell
and Gibson responsible for 104.5 grams of oxycodone, or the
equivalent of at least 2,612 40-mg oxycodone pills. This
yielded a base offense level of 30.
The court also rejected Gibson’s argument that only a por-
tion of the total weight should be attributed to her. Although
14 UNITED STATES v. BELL
it "[m]ay well have been that Ms. Gibson was not present at
all times when the defendant Bell distributed or caused to be
distributed drugs, . . . I believe it is a reasonable inference
from the evidence that she had full knowledge of the scope of
the conspiracy and quantity of drugs involved." J.A. 427.
Based on its determinations (as described above), the dis-
trict court concluded that the final Guidelines range for Bell
was 97 to 121 months and the final Guidelines range for Gib-
son was 70 to 87 months.
E.
The Appellants then turned to their presentations under 18
U.S.C. § 3553(a). The government did not present additional
evidence. The defense presented the testimony of Christy Par-
ker, another of Gibson’s daughters and Misty’s twin sister.
Among other things, she testified that her grandmother, Bell,
"has diabetes, heart problems, blood pressure problems, she
has back problems, [and] other things I’m not really certain
on." J.A. 431. Christy testified that her grandmother was on
many prescriptions, but she could not say the exact amount
because "she has so many." Id. When asked whether she had
ever seen her grandmother take oxycodone, she responded
that she had, and that it was for pain. Id.
The government argued for sentences at the high end of the
Guideline ranges. Bell’s counsel argued for a sentence of pro-
bation, especially given Bell’s poor health. Gibson’s counsel
argued for a below-Guidelines sentence as well. The district
court declined to depart downward, and imposed sentences of
120 months for Bell (on all counts, concurrent) and 72 months
for Gibson (on all counts, concurrent). The Appellants have
timely appealed.
II.
We review a sentence for abuse of discretion. Gall v.
United States, 552 U.S. 38, 51 (2007). We first ensure that the
UNITED STATES v. BELL 15
district court committed no significant procedural error.
United States v. Evans, 526 F.3d 155, 161 (4th Cir. 2008).
Significant procedural errors include "failing to calculate (or
improperly calculating) the Guidelines range, treating the
Guidelines as mandatory, failing to consider the [18 U.S.C.]
§ 3553(a) factors, selecting a sentence based on clearly erro-
neous facts, or failing to adequately explain the chosen sen-
tence." Gall, 552 U.S. at 51. If a sentence is procedurally
reasonable, we then consider the substantive reasonableness
of the sentence under an abuse-of-discretion standard, taking
into account the totality of the circumstances. Id. A sentence
within the Guidelines range may be accorded an appellate
presumption of reasonableness. Rita v. United States, 551
U.S. 338, 346–56 (2007).
III.
On appeal, Bell and Gibson argue the district court commit-
ted significant procedural errors by failing to properly calcu-
late the Guidelines range, and/or failing to adequately explain
how the court calculated the base offense levels. The Appel-
lants’ principal argument is that the district court erred in its
calculation of the total weight of the oxycodone pills attribut-
able to the conspiracy, from which each base offense level
was determined. For the following reasons, we find merit in
the Appellants’ contentions and we shall remand for further
proceedings.
A.
The Sentencing Guidelines include a Drug Quantity Table
that provides base offense levels that correspond to certain
quantities of enumerated controlled substances. U.S.S.G.
§ 2D1.1(c). For controlled substances not on the Drug Quan-
tity Table, the Guidelines include Drug Equivalency Tables,
which convert the weight of the substances to an "equivalent
quantity" of marijuana. Id. § 2D1.1, cmt. n.10(A)(ii). In con-
spiracy cases, base offense levels are determined based on "all
16 UNITED STATES v. BELL
acts and omissions committed, aided, abetted, counseled,
commanded, induced, procured, or willfully caused by the
defendant," id. § 1B1.3(a)(1)(A), as well as the "reasonably
foreseeable acts and omissions of others in furtherance of the
jointly undertaken criminal activity," which include any
"criminal plan, scheme, endeavor, or enterprise undertaken by
the defendant in concert with others, whether or not charged
as a conspiracy." Id. § 1B1.3(a)(1)(B). In cases of jointly
undertaken criminal activity involving controlled substances,
the Guidelines hold a defendant "accountable for all quantities
of contraband with which he was directly involved and . . . all
reasonably foreseeable quantities of contraband that were
within the scope of the criminal activity that he jointly under-
took." Id. § 1B1.3 cmt. n.2. A defendant’s "relevant conduct"
does not, however, include the conduct of members of a con-
spiracy occurring prior to when the defendant joined the con-
spiracy, "even if the defendant knows of that conduct." Id.
For sentencing purposes, the government must prove the
drug quantity attributable to a particular defendant by a pre-
ponderance of the evidence. United States v. Randall, 171
F.3d 195, 210 (4th Cir. 1999). When the drug quantity is not
proven by actual seizures or comparable direct evidence, the
government must present evidence from which the sentencing
court may "approximate the quantity." U.S.S.G. § 2D1.4, cmt.
n.2. In such cases the Guidelines do not recommend a particu-
lar method for determining quantity; any of various methods
might be proper on a particular set of facts. The district
court’s obligation, in addition to assessing the reliability of
evidence, is to choose a method for interpreting the evidence
that ensures that only drug quantities proven by a preponder-
ance are attributed to a defendant.
For example, although we have approved reliance on direct
or hearsay testimony of lay witnesses as to the quantities
attributable to a defendant, see United States v. Cook, 76 F.3d
596, 604 (4th Cir. 1996), we have cautioned that when the
approximation is based only upon "uncertain" witness esti-
UNITED STATES v. BELL 17
mates, district courts should sentence at the low end of the
range to which the witnesses testified. United States v. Samp-
son, 140 F.3d 585, 592 (4th Cir. 1998); see also U.S.S.G.
§ 6A1.3(a) (policy statement) (permitting sentencing courts to
rely on "relevant information without regard to its admissibil-
ity under the rules of evidence applicable at trial, provided
that the information has sufficient indicia of reliability to sup-
port its probable accuracy"). Similarly, although district
courts may rely on cash amounts linked credibly to defen-
dants’ purchases or sales of narcotics and properly converted
to narcotics quantities, courts using such an approach must
ensure that doing so does not result in double counting of both
the narcotics and the proceeds of their sale. See United States
v. Morsley, 64 F.3d 907, 915-16 (4th Cir. 1995).
Notably, however, apart from its Guidelines calculation, in
every case, "[r]egardless of whether the district court imposes
an above, below, or within-Guidelines sentence, it must place
on the record an ‘individualized assessment’ based on the par-
ticular facts of the case before it." United States v. Carter, 564
F.3d 325, 330 (4th Cir. 2009) (quoting Gall, 552 U.S. at 50).
The explanation must be sufficient to allow for "meaningful
appellate review," id. (quoting Gall, 552 U.S. at 50), such that
the appellate court need "not guess at the district court’s ratio-
nale." Id. at 329.
B.
The Drug Quantity and Drug Equivalency Tables include
controlled substances of all types, including those designated
on Schedules I, II, III, IV and V under the Controlled Sub-
stances Act. Schedule I substances are those that have a "high
potential for abuse" and "no currently accepted medical use in
treatment in the United States." 21 U.S.C. § 812(b)(1). Sched-
ule V substances, at the other end of the controlled-substances
spectrum, have a currently accepted therapeutic medical use
and a relatively low potential for abuse. Id. § 812(b)(5). As an
opiate pain-relieving medication, oxycodone is a Schedule II
18 UNITED STATES v. BELL
substance, meaning that it "has a currently accepted medical
use" but "has a high potential for abuse," and its abuse "may
lead to severe psychological or physical dependence." Id.
§ 812(b)(2); 21 C.F.R. § 1308.12(b)(1)(xiii).4
The principal distinguishing characteristic between sub-
stances on Schedule I and those on the other Schedules is that
non-Schedule I substances have at least one currently
accepted medical use, and therefore can be possessed and sold
legally in some circumstances. For obvious reasons, Congress
has expressly stated that a person may not be prosecuted for
simple possession of a non-Schedule I controlled substance
when the person obtained the drug "pursuant to a valid pre-
scription or order, from a practitioner, while acting in the
course of his professional practice." 21 U.S.C. § 844(a).
That distinction potentially becomes critical in cases where
a person is convicted of conspiracy to possess with intent to
distribute a controlled substance. Where there is no evidence
that any of the drugs obtained by members of a conspiracy
were obtained or possessed legally, all reasonably foreseeable
quantities possessed by conspiracy members with intent to
distribute and within the scope of the criminal activity
undertaken by a particular defendant may be considered "rele-
vant conduct" attributable to that defendant. See, e.g., United
States v. Iglesias, 535 F.3d 150, 160 (3d Cir. 2008) (holding
that methamphetamine retained for personal use by the defen-
dant, who had been convicted of conspiracy to distribute the
substance and never argued any of the methamphetamine was
lawfully obtained, was properly considered "contraband with
which he was directly involved" and therefore "relevant con-
duct"); United States v. Asch, 207 F.3d 1238, 1243-44 (10th
Cir. 2000) (same, although defendant was also convicted of
conspiracy to possess with intent to distribute methamphet-
4
Schedules of controlled substances are revised regularly. See 21 U.S.C.
§ 812(a). Revised schedules are published in the Code of Federal Regula-
tions, Part 1308 of Title 21, Food and Drugs.
UNITED STATES v. BELL 19
amine). But in a subset of non-Schedule I cases, where some
or all of the drugs possessed by one or more conspiracy mem-
bers were obtained and possessed pursuant to a valid prescrip-
tion, that general rule potentially breaks down, because
"relevant conduct" only includes "reasonably foreseeable acts
and omissions of others in furtherance of the jointly
undertaken criminal activity." U.S.S.G. § 1B1.3(a)(1)(B)
(emphasis added). Where, as here, a defendant has been con-
victed of conspiracy to possess with intent to distribute and/or
to distribute a quantum of controlled substances which she
lawfully obtains and possesses, although it may be tautologi-
cal to say so, only those quantities the defendant conspired or
intended to possess unlawfully, i.e., with intent to distribute,
are "relevant conduct," because a defendant is only account-
able for "reasonably foreseeable quantities of contraband that
were within the scope of the criminal activity that he jointly
undertook." Id. § 1B1.3 cmt. n.2. In those cases, presuming
that the full quantity possessed by conspiracy members is
"contraband . . . within the scope of the criminal activity,"
without requiring the government to prove and without a fac-
tual finding by the district court explicating the evidence sup-
porting that finding, creates an unacceptably high risk that a
defendant will be punished for drug quantities a portion of
which was lawfully obtained, possessed and consumed.
In such a case involving a valid prescription, if at sentenc-
ing the government wishes to use the total quantity prescribed
to one or more conspiracy members as evidence of the quan-
tity of "contraband . . . within the scope of the [conspiracy to
possess with intent to distribute]," it must also provide evi-
dence, and the district court must make a finding, of some-
thing more—for example (1) that the conspiracy actually
distributed a particular amount; (2) that the person who was
prescribed the drug lawfully kept and consumed only a por-
tion (or none) of the prescribed amount; (3) that the pills were
obtained fraudulently and thus cannot be considered to have
been lawfully obtained and possessed, see 21 U.S.C.
§ 843(a)(3) (making it unlawful to "acquire or obtain posses-
20 UNITED STATES v. BELL
sion of a controlled substance by misrepresentation, fraud,
forgery, deception, or subterfuge"); or (4) that "each and
every pill" obtained, even if pursuant to a valid prescription,
was obtained "with the intent that it would or could be distrib-
uted." See, e.g., United States v. Marks, 365 F.3d 101, 106
(1st Cir. 2004). Without requiring such additional factual
findings by a district court, where a defendant lawfully
obtained 100 pills per month pursuant to a valid prescription
and was proven to have sold or transferred just one, we
encounter the risk of sustaining a finding that the sale of the
one pill could render the possession of all 100 pills unlawful,
by attributing an intent to distribute the remaining 99 pills
without any proof whatsoever to support such a finding.5
C.
We turn now to the facts in the case at bar. As stated above,
the probation officer calculated the total amount of oxycodone
prescribed to Bell from January 2004 to August 2009 as 187.8
grams, a Guidelines equivalent of 1,258.26 kilograms of mari-
juana, and attributed that full amount to the conspiracy. The
district court did not go that far, however, instead attributing
104.5 grams of oxycodone, the Guidelines equivalent of 700
kilograms of marijuana, to the conspiracy and by extension to
Bell and Gibson.6 But the district court’s explanation for how
5
The government cites a string of cases for the proposition that "[d]rugs
obtained by conspirators for personal use in the course of a conspiracy
may be included in the drug weight." Gov’t Br. at 22 (citing United States
v. Page, 232 F.3d 536, 542 (6th Cir. 2000); United States v. Antonietti, 86
F.3d 206, 209 (11th Cir. 1996); United States v. Fregoso, 60 F.3d 1314,
1328 (8th Cir. 1995); United States v. Snook, 60 F.3d 394, 395 (7th Cir.
1995); United States v. Wood, 57 F.3d 913, 920 (10th Cir. 1995); United
States v. Innamorati, 996 F.2d 456, 492 (1st Cir. 1993)). But the drugs in
those cases were either Schedule I substances, no use of which would have
been lawful, or Schedule II substances where there was no evidence that
any of the drugs were obtained and/or consumed lawfully. Thus, the rea-
soning in those cases is inapt here.
6
We note that the district court’s 700 kilogram finding is at the very top
of the drug quantity table for an offense level of 28.
UNITED STATES v. BELL 21
it calculated that quantity is insufficient to allow for "mean-
ingful appellate review," Gall, 552 U.S. at 50, as we now
explain.
The principal shortcoming lies in the district court’s con-
clusion that even if a portion of the oxycodone prescribed to
Bell was lawfully possessed and consumed by her, the entire
amount prescribed is "properly included in the quantity of
drugs" for purposes of calculating the Appellants’ sentences
so long as "a drug conspiracy is involved." As explained
above, non-Schedule I substances that a conspiracy member
obtains, possesses, and consumes pursuant to a valid prescrip-
tion generally do not constitute "relevant conduct" for sen-
tencing purposes.
Here, there is no dispute that Bell received her pills using
a valid prescription issued to her by physicians at a single
institution, the St. Mary’s pain center, and there was more
than a mere scintilla of evidence that Bell lawfully consumed
some of the pills. As the government concedes, she passed
occasional opiate testing and pill counts during her appoint-
ments, and her granddaughter Christy testified that she had
seen Bell take oxycodone. To the extent Bell and her co-
conspirators conspired to possess with intent to distribute or
to distribute a particular quantity of her pills, Bell could be
sentenced for that quantity, as could Gibson (or any other
similarly-situated co-conspirator) to the extent the quantity
was reasonably foreseeable and in furtherance of the jointly
undertaken criminal activity. Similarly, to the extent Gibson
herself possessed oxycodone, she could be sentenced for that
full amount, because there is no suggestion that Gibson could
lawfully possess any quantity of the drug. But absent a find-
ing (adequately supported by reliable evidence) that the entire
quantity prescribed to Bell was "within the scope of the crimi-
nal activity" she and her co-conspirators undertook, see
U.S.S.G. § 1B1.3 cmt. n.2, it would be improper to include in
the drug quantity pills Bell lawfully consumed—both as to
Bell, who lawfully possessed and consumed at least a portion
22 UNITED STATES v. BELL
of the oxycodone prescribed to her, and as to Gibson, whose
sentence, like Bell’s, was calculated based on the full amount
prescribed to Bell.7
None of the above analysis is surprising because it is clear
that the government and the district court recognized the need
for some inquiry beyond finding the sum total of Bell’s pre-
scriptions. After all, the government presented the co-
conspirators’ testimony, and the district court considered that
testimony; if the court had been relying exclusively on the
prescription records there would have been no reason to con-
sider that testimony (or to take a reduction from the total drug
weight based on that testimony and the other evidence in the
record). But the nature of the court’s consideration of that tes-
timony and any specific calculations from it are simply not
reflected in the record, hampering our ability to review the
sentence for procedural reasonableness.
The extent of the district court’s explanation for its 700-
kilogram-of-marijuana finding was the following. The court
"credit[ed] [the witnesses’] testimony in regard to the quantity
of drugs" despite any "discrepancies" because to the extent
there were discrepancies they were "not material." The court
then accepted "the upper level" of the amounts testified to
because those amounts were "corroborated by" the quantity
prescribed to Bell. In conclusion, but rather inexplicably, the
court "partially sustain[ed]" the Appellants’ objection to the
total drug quantity and found that Bell "was responsible for
7
Because the government does not genuinely dispute that Bell obtained
all of her pills using prescriptions issued by physicians at St. Mary’s, there
is no allegation that she engaged in so-called "doctor shopping," secretly
obtaining prescriptions from multiple physicians. We need not, and there-
fore do not, decide whether such conduct would have rendered the full
amount prescribed "within the scope of the criminal activity," or at least
rendered the quantity of legitimately obtained pills sufficiently de minimis
that the full amount received could constitute a reasonable approximation
of the scope of the criminal activity.
UNITED STATES v. BELL 23
distribution of at least 700 kilograms equivalency of mari-
juana."
There is no explanation in the record of any of several
underlying factual findings, at least some of which would
have been necessary to reach the 700-kilogram number,
including: (1) the range of sales each witness testified to; (2)
the time period during which each witness purchased oxyco-
done from the Appellants, bearing in mind that there was no
testimony as to transactions at the front end or the tail end of
the charged conspiracy, see supra n.3; (3) the sum of the
"upper limit[s]" and lower limits of each witness’s testimony;
(4) an approximation of the quantity of prescribed pills Bell
herself consumed; and (5) whether (a) Bell and Gibson were
also distributing pills prescribed to Bell’s husband, (b) the
pills Kim Smith and Tim Pace described were the same or dif-
ferent pills and whether their maximum per-month quantity
was 40 or 60 or some other number, (c) the pills Joyce and
Timothy Hopkins described were the same or different pills,
and (d) Misty Parker re-sold some of the pills she bought to
Leslie Clasby and/or Joyce Hopkins.8 In short, to support its

[This footnote expresses solely the views of Judge Davis]
I hasten to make two observations. First, I do not suggest that any one
or more of the specific queries listed above is or should be either a neces-
sary or a sufficient basis for a permissible finding of drug quantity in any
particular case. Like relevant conduct in any case, the district court
approaches its task based on the facts and circumstances presented. Sec-
ond, I recognize that some of these queries, such as the quantity Bell her-
self consumed, may be more difficult for the government to prove than
others. But that does not relieve the government of proving such facts by
a preponderance of the evidence at sentencing. See Randall, 171 F.3d at
210.
A majority of the panel declines to join in this footnote but otherwise
joins in this opinion for the court. See post (Hamilton, J., concurring). I
am at a loss to understand my good colleagues’ concerns over my forth-
right acknowledgement in this footnote that part of the government’s bur-
den in the circumstances of this case may include offering evidence upon
which the district court might reasonably infer how much of her pre-
24 UNITED STATES v. BELL
scribed oxycodone Appellant Bell did (or did not) consume herself.
Indeed, that is the very burden the government rightfully assumed in call-
ing six co-conspirator witnesses to testify at the sentencing hearing: to
provide an evidentiary basis for the district court to infer total drug quan-
tity.
In saying as it does that "I read nothing in the court’s opinion that says
a defendant is relieved of her obligation to produce some evidence con-
cerning her personal consumption once the government establishes, by a
preponderance of the evidence, that an otherwise valid prescription was
part of the conduct of the conspiracy, with the government shouldering the
ultimate burden of proof on the question of drug quantity," the concur-
rence confuses our holding. Perhaps in some future case we might be
required to decide whether a defendant in circumstances similar to Bell’s
bears a burden of production as to his or her personal consumption of a
validly prescribed medication. But that question is not before us; in this
case, whatever burden of production Appellant Bell may have had was sat-
isfied by the very evidence produced by the government itself, along with
the drug screens and evidence of her longstanding legitimate medical
needs. Thus, to the extent the concurrence purports to announce a rule
imposing an "obligation" on such a defendant to produce evidence of per-
sonal consumption at sentencing, it constitutes mere dicta and, in any
event, was not argued by the government. The problem is compounded by
the fact that the case the concurrence relies upon, Asch, 207 F.3d at 1246,
is clearly distinguishable, see supra at 18-19, and the statement from the
case Asch relied upon, United States v. Wyss, 147 F.3d 631, 633 (7th Cir.
1998), was not only dicta but was also clearly labeled as such. See id.
("Maybe, when the defendant buys drugs both for his own consumption
and for resale, he has some burden of producing evidence concerning the
amount that he consumed . . . . This we need not decide."); see also Pierre
N. Leval, Judging Under The Constitution: Dicta About Dicta, 81 N.Y.U.
L. Rev. 1249, 1268-69 (2006) (criticizing the "progressive distortion"
through which "a hint becomes a suggestion, is loosely turned into dictum
and finally elevated to a decision") (quoting United States v. Rabinowitz,
339 U.S. 56, 75 (1950) (Frankfurter, J., dissenting)).
To the extent the concurrence is instead advising district judges on how
to draw inferences from evidence at sentencing, they hardly need our
instruction on that ordinary task in which they engage daily; I have no
doubt they are already well-equipped to call fanciful defense assertions
that large quantities of narcotics were consumed by the defendant what
they are: fanciful assertions.
UNITED STATES v. BELL 25
finding that the conspiracy’s total drug quantity was the
equivalent of 700 kilograms of marijuana, the district court
was obliged to explain how the witnesses’ testimony, together
with the prescription records and other probative evidence
before it, proved by a preponderance that the equivalent of
2,612 40-mg pills of oxycodone was "within the scope of the
criminal activity" undertaken by the Appellants and their co-
conspirators. This the district court failed to do, requiring that
we remand for resentencing.9
D.
Recognizing that the evidence plainly supports a finding
that Bell consumed some of the pills and that the district
court’s explanation may have been inadequate, the govern-
ment offers two final arguments. First, it argues that to be "le-
gally obtained" prescription narcotics must be medically
necessary, and because Bell sold most of her prescribed pills,
the pills were not medically necessary and therefore were not
legally obtained. But that argument proves too much. Initially,
we can discern no good reason to craft a rule that any pre-
scription drug that is sold illegally by the patient who obtains
the prescription to another without a prescription is "medi-
cally unnecessary" to the patient as a matter of law. Second,
even if we were to agree that a mere sale or transfer of a por-
tion of the pills covered by a prescription renders that portion
medically unnecessary, there is no good reason to say that all
pills in the prescription are rendered medically unnecessary.
So viewed in this case, although at least some, perhaps most,
of the pills were medically unnecessary, that does not prove
that all of them were medically unnecessary. Thus, we reject
the government’s contention.
9
Although procedural sentencing errors can be harmless under the stan-
dard provided by Federal Rule of Criminal Procedure 52(a), see United
States v. Lynn, 592 F.3d 572, 576 (4th Cir. 2010), the government does not
argue that if there is error here the error was harmless.
26 UNITED STATES v. BELL
Second, the government seeks to minimize the absence of
findings on the record through its own ex post reconstruction
of what the district court’s calculations must have been to
reach its decision to attribute the equivalent of 700 kilograms
to the conspiracy. As we have explained, however, "an appel-
late court may not guess at the district court’s rationale,
searching the record for statements by the Government or
defense counsel or for any other clues that might explain a
sentence." Carter, 564 F.3d at 329-30. The Supreme Court’s
recent sentencing jurisprudence "plainly precludes any pre-
sumption that, when imposing a sentence, the district court
has silently adopted arguments presented by a party." Id. at
329. "Rather, ‘the district judge,’ not an appellate court, ‘must
make an individualized assessment based on the facts pres-
ented’ to him.’" Id. (quoting Gall, 552 U.S. at 49-50).
We emphasize that none of this is to say, of course, that the
district court should have disregarded Bell’s prescription
records in calculating drug quantity, or even that on remand
the district court will be precluded from reaching the same
total drug weight. Plainly, the amount Bell received was a rea-
sonable starting point; and, a district court’s rough approxi-
mation (as reflected here by the court’s near 45% reduction in
the PSR’s recommended drug weight) will in many cases pass
muster. But under the circumstances presented in this record,
without a clear factual finding on how much of the prescrip-
tion Bell herself consumed and/or some other factual basis
reflecting the court’s assessment of the co-conspirator testi-
mony to show that 104.5 grams was the amount of oxycodone
the conspiracy members unlawfully possessed with intent to
distribute, there is an unacceptably high risk that the relevant
total drug weight may have been inflated.
IV.
Gibson offers another, separate, challenge to her own sen-
tence. Gibson argues that, whatever the total drug quantity
attributable to the conspiracy might be, the district court erred
UNITED STATES v. BELL 27
in holding her responsible at sentencing for that full amount.
She argues the evidence showed that she was involved in drug
sales only beginning in or after May 2008, and therefore only
pills sold between May 2008 and July 2009 should have been
attributed to her.
As stated above, because the record does not adequately
support the district court’s calculation of the conspiracy’s
total drug quantity, we are vacating each Appellant’s sen-
tence. Thus, the district court will have the opportunity in any
event to revisit the evidence of the extent and timing of Gib-
son’s involvement in the conspiracy. We note, however, that
the district court’s rejection of Gibson’s argument turned on
its finding that Gibson "had full knowledge of the scope of the
conspiracy and quantity of drugs involved." J.A. 427. Gib-
son’s "knowledge" of the scope of Bell’s drug sales, however,
is only part of the analysis; under the Guidelines the full
amount of oxycodone sold or transferred by Bell is only
attributable to Gibson for drug weight purposes if that full
amount was reasonably foreseeable to Gibson and within the
scope of the criminal activity that she jointly undertook with
Bell. See U.S.S.G. § 1B1.3 cmt. n.2. Moreover, if Gibson did
not join the conspiracy until May 2008, oxycodone distributed
by Bell or other conspiracy members before that date could
not be considered "relevant conduct," even if Gibson knew of
that conduct. Id.
On remand the district court may well decide as a factual
matter that Gibson’s conduct satisfies the standard for attri-
buting to her the full amount possessed by conspiracy mem-
bers with intent to distribute. After all, although the trailer
park lease presented at sentencing was from May 2008 and
there was evidence Gibson lived somewhere else at some
point in the years prior to 2008, there was no evidence of
where she lived between approximately 2005 and May 2008.
Moreover, the district court acknowledged that there were
some "discrepancies in the testimony of witnesses based on a
lack of memory" as to the precise nature of Gibson’s involve-
28 UNITED STATES v. BELL
ment, and "accept[ed] their testimony in spite of that." J.A.
427. Nonetheless, because we cannot reliably determine from
the record whether the district court found that the full quan-
tity of pills attributable to Bell was "reasonably foreseeable"
to Gibson and "within the scope of the criminal activity that
[she] jointly undertook," U.S.S.G. § 1B1.3 cmt. n.2, we are
unable to affirm the district court’s decision to attribute the
full amount to Gibson.
V.
For the foregoing reasons, we vacate the judgments and
remand for further proceedings consistent with this opinion.
VACATED AND REMANDED
HAMILTON, Senior Circuit Judge, concurring in part and
concurring in the judgment:
I concur in the court’s opinion except Footnote 8. I write
separately to make two observations. First, the court’s opinion
in this fact-intensive case is limited to a situation in which a
defendant (here, Bell) obtained drugs and then entered into an
agreement with codefendants (here, Gibson and others) to
possess with the intent to distribute a portion of those drugs.
For obvious reasons, the reasonably foreseeable quantities
within the scope of the criminal activity the defendant and the
downstream codefendants agreed to undertake do not involve
the amount the defendant withheld for personal consumption.
Second, I read nothing in the court’s opinion that says a
defendant is relieved of her obligation to produce some evi-
dence concerning her personal consumption once the govern-
ment establishes, by a preponderance of the evidence, that an
otherwise valid prescription was part of the conduct of the
conspiracy, with the government shouldering the ultimate bur-
den of proof on the question of drug quantity. See, e.g.,
United States v. Asch, 207 F.3d 1238, 1246 (10th Cir. 2000)
("Although the defendant bears the burden of producing evi-
UNITED STATES v. BELL 29
dence of her intent to consume, we emphasize that the ulti-
mate burden of proof on the quantity of drugs involved in the
offense remains with the government at all times.").
I am authorized to state that Judge Floyd joins in this opin-
ion.
