Opinion of the Court
SULLIVAN, Chief Judge:Appellant was tried by a general court-martial composed of a military judge sitting alone at Travis Air Force Base, California, on January 18 and 19, 1990. Pursuant to his pleas of guilty, he was found guilty of attempting to wrongfully use methamphetamine (by consuming placebos) on divers occasions between July 5 and 27, 1989, and attempting to wrongfully possess the same (by acquiring a placebo) on July 14, 1989. Art. 80, Uniform Code of Military Justice, 10 USC § 880. In addition, pursuant to his conditional pleas, he was found guilty of wrongfully using methamphetamine on divers occasions between April 1 and July 27, 1989, in violation of Article 112a, UCMJ, 10 USC § 912a. He was sentenced to a bad-conduct discharge, confinement and forfeiture of $400 pay per month for 9 months, and reduction to airman basic. The convening authority approved this sentence, and the Court of Military Review affirmed on January 10, 1991, in an unpublished opinion.
*216This Court granted review of the following question of law:
WHETHER THE MILITARY JUDGE ERRED BY DENYING APPELLANT’S MOTION TO SUPPRESS HIS CONFESSION FOR LACK OF ADEQUATE CORROBORATION AS REQUIRED BY MIL.R.EVID. 304(g).
We hold that this record contains more than the slight evidence of corroboration required by Mil.R.Evid. 304(g), Manual for Courts-Martial, United States, 1984, for admission of appellant’s voluntary confession at this court-martial. See generally United States v. Yeoman, 25 MJ 1, 4 (CMA 1987).
Appellant was charged with various drug offenses occurring between January 1 and July 27, 1989. The original specifications state:
CHARGE I: VIOLATION OF THE UCMJ, ARTICLE 80.
Specification 1: In that [appellant] did, at or near Travis Air Force Base, California, on divers occasions between on or about 5 July 1989 and on or about 27 July 1989, attempt to wrongfully use methamphetamine.
Specification 2: In that [appellant] did, at or near Travis Air Force Base, California, on or about 14 July 1989, attempt to wrongfully possess some amount of methamphetamine.
CHARGE II: Violation of the UCMJ, Article 112a.
Specification: In that [appellant] did, at or near Travis Air Force Base, California, on divers occasions, between on or about 1 January 1989 and on or about 27 July 1989, wrongfully use methamphetamine.
(Emphasis added.)
Appellant, however, admitted during his guilty-plea inquiry that he used actual methamphetamine in his room on only two occasions during the period from April 1 to July 27,1989. He acknowledged that those uses (the specification of Charge II) were distinct from his use and possession of placebo methamphetamine on July 5 and 27, 1989 (specifications 1 and 2 of Charge I).
Prior to entering his pleas, appellant had moved to suppress his confession of July 27, 1989, on the basis of a lack of corroboration required by Mil.R.Evid. 304(g). This confession states:
I Carmen M. Maio, have been stationed at Travis since April 1988. Duane Spencer (Spence) has been my roommate since August ’88. The first time I had used methamphetamine, crank, was approx. January 1989. Since Jan 1989 I have used crank approximately 10-12 times. The places at which this occurred were either in my room, bldg. 1346 Rm. A-4, or before going to Folsom Lake to jet ski. I would use crank in my room before going jet skiing, or on my free time always keeping it to myself and not involving others. The crank was in powder form, and I wo[u]ld inhale it for digestion. I knew it was crank from its distinct smell and it would make me feel like I had drank a pot of coffee. On the occasions I had used crank I had gotten it through Spence or was turned on by him, occasionally using with him (10-12 times). Most of the time I would give Spence money and Spence would get it from someone else, neither one of us actually being dealers. I think Spence would get the crank at Gigi’s from civilians. I don’t think Spence ever bought crank from military members, and I don’t know of any military members who sell drugs. Around the middle of July ’89 I bought $20.00 worth of what I thought was crank from Ron, a guy I met at Gigi’s. I used about half of what I bought and realizing that it was in fact not crank, I did not use what was left. Around the beginning of July 89, I used about half a line of what I thought was crank, being turned on from Ron. This happened in Ron’s car somewhere in Fairfield. I never used crank on duty or before going to work. It was for my personal use and I had never dealt to anyone nor witnessed Spence to deal. The reasons I would use crank is because it made me feel productive, gave an ener*217gy boost. I do not want what has happened to be detrimental to my career. Realizing this I will never use it again. I do like the military and wish to be a part of the military team. I will try to help in any way possible.

Evidence was taken at a hearing prior to pleas on admissibility of this confession, including testimony by Special Agent Sal-yards, the police officer who obtained it on July 27, 1989. Sergeant Brainard, an undercover agent for the security police, also testified inter alia concerning additional admissions made to him by appellant on July 5, 1989, as well as other matters observed during his undercover operation against appellant and his roommate during the charged period. (See appendix.) Finally, Sergeant Keith, appellant’s supervisor, testified about appellant’s work schedule and duties during this period.
The military judge ruled that the challenged confession was sufficiently corroborated to be admitted at this court-martial. He also articulated for the record his reasons for this ruling. The Court of Military Review also held that the confession was properly corroborated and articulated its corroboration rationale. We now affirm the court below.
Our starting point in resolving the granted issue is the voluntary confession written and signed by appellant and given to Agent Salyards on July 27, 1989. In this confession, appellant essentially admitted that he had intentionally and knowingly used methamphetamines (crank) approximately 10 to 12 times since January 1, 1989. He further stated that he normally inhaled these drugs in powder form in private but also occasionally in the presence of his roommate, Duane Spencer. He particularly noted that such use had occurred before going jet skiing. Finally, he identified Spencer as his drug supplier whose source he further denoted as a bar named Gigi’s.
Clearly, this confession established all the elements of unlawful drug use in violation of Article 112a. See para. 37(b)(2), Part IV, Manual, supra. Moreover, appellant at no time claimed his confession was involuntary or that he was not properly advised of his rights prior to making it. See United States v. Yeoman, supra at 4. See Mil.R.Evid. 304(a) and (c)(3). Instead, he rested his suppression motion on Mil.R.Evid. 304(g) and contended his confession was not adequately corroborated.
Mil.R.Evid. 304(g) states:
(g) Corroboration. An admission or a confession of the accused may be considered as evidence against the accused on the question of guilt or innocence only if independent evidence, either direct or circumstantial, has been introduced that corroborates the essential facts admitted to justify sufficiently an inference of their truth. Other uncorroborated confessions or admissions of the accused that would themselves require corroboration may not be used to supply this independent evidence. If the independent evidence raises an inference of the truth of some but not all of the essential facts admitted, then the confession or admission may be considered as evidence against the accused only with respect to those essential facts stated in the confession or admission that are corroborated by the independent evidence. Corroboration is not required for a statement made by the accused before the court by which the accused is being tried, for statements made prior to or contemporaneously with the act, or for statements offered under a rule of evidence other than that pertaining to the admissibility of admissions or confessions.
(1) Quantum of evidence needed. The independent evidence necessary to establish corroboration need not be sufficient of itself to establish beyond a reasonable doubt the truth of facts stated in the admission or confession. The independent evidence need raise only an inference of the truth of the essential facts admitted. The amount and type of evidence introduced as corroboration is a factor to be considered by the trier of *218fact in determining the weight, if any, to be given to the admission or confession.
(2) Procedure. The military judge alone shall determine when adequate evidence of corroboration has been received. Corroborating evidence usually is to be introduced before the admission or confession is introduced but the military judge may admit evidence subject to later corroboration.
(Emphasis added.)
This Court has considered the above Manual provision on several occasions. We have consistently held that it does not require independent evidence of the “corpus delicti" of the confessed offense (see 7 J. Wigmore, Evidence § 2072 (Chadbourn rev.1978) for a discussion of that term) but, instead, that it requires independent evidence which establishes the trustworthiness of the confession. United States v. Rounds, 30 MJ 76, 80-81(CMA), cert. denied, — U.S. ---, 111 S.Ct. 130, 112 L.Ed.2d 98 (1990); United States v. Melvin, 26 MJ 145 (CMA 1988); United States v. Yeoman, supra. These holdings are consistent with Supreme Court precedent and with practice in Federal civilian courts such that it can be realistically said in the Federal sector that the “corpus delicti” corroboration rule no longer exists. United States v. Kerley, 838 F.2d 932, 939-40 (7th Cir.1988). See generally C. Wright, Federal Practice and Procedure: Criminal 2d § 414 at 516 (1982); 7 J. Wigmore, Evidence § 2071 at 511-16. The bottom line is that the corroborating evidence must raise only an inference of truth1 as to “the essential facts admitted” in the confession. See State v. Harris, 215 Conn. 189, 575 A.2d 223, 226-27 (1990).
We note that the following evidence independent of appellant’s confession was adduced at the suppression hearing:
(1) Direct testimony from undercover agent Sergeant Brainard that appellant had earlier admitted all confessed facts to him on July 5, 1989.
(2) Direct testimony from undercover agent Sergeant Brainard that he observed Spencer, appellant’s roommate and putative supplier, produce and use methamphetamine on June 2, 1989, at or near “Gigi’s.”
(3) Written statement by Sergeant Brainard that Spencer admitted using methamphetamine, in the presence of his roommate, when jet skiing.
(4) Direct testimony from undercover agent, Sergeant Brainard, that during the charged period he twice observed appellant readily ingest placebo methamphetamine by snorting it from a key.
[This portion of our opinion is not a quotation.]
In several ways the above evidence raised an inference of truth as to the actual drug use admitted by appellant in his July 27th confession. First, proof of appellant’s deliberate consumption of substances which he thought were methamphetamine on two occasions within the time period covered in his confession established his ability and inclination to use the drug methamphetamine as he confessed. See United States v. Melvin, supra 26 MJ at 147. Second, evidence of his earlier admissions to the undercover agent confirmed the times and venue of his confessed methamphetamine use at least to an extent feasible for essentially private drug use.2 See *219State v. Harris, supra 575 A.2d at 226. Third, proof of Sergeant Brainard’s observations of Spencer and the latter’s demonstrated capacity to produce drugs from Gigi’s during the period covered in his confession established appellant’s access to the drugs which he confessed to using. United States v. Rounds, 30 MJ at 80. Finally, the marked similarity of the essential facts asserted in appellant’s spontaneous admission on July 5, 1989, and in his subsequently advised confession on July 27, 1989, imparted a strong ring of truth to his later statement.3 See generally United States v. Yeoman, supra at 4-5. Accordingly, based on both appellant’s earlier admissions to Sergeant Brainard and the other evidence noted above, we conclude that his later voluntary confession was shown to be sufficiently trustworthy for admission at his court-martial. See generally United States v. Basile, 771 F.2d 307, 311 n. 3 (7th Cir.1985).
The decision of the United States Air Force Court of Military Review is affirmed.
Judges CRAWFORD and GIERKE concur.APPENDIX
Q: When you produced this placebo methamphetamine, how did you identify it to the accused?
A: I called it crank. That is what the common term is.
Q: For what?
A: Methamphetamine.
Q: So he snorted some up his nose that day on the 5th?
A: Yes ma’am.
Q: What did you do after snorting this placebo methamphetamine?
A: We continued to drive around a little bit. We had some further conversation. Then we went back to the club.
Q: I’d like to focus your attention a little bit on the conversation you had with the accused on the 5th of July. Did the accused on the 5th of July, during this time in the car when this placebo methamphetamine was snorted, did he mention any prior uses of methamphetamine on his part?
A: Yes ma’am.
Q: How did that come up?
A: We were talking about jet skiing. He stated the last week, he and his roommate had snorted some methamphetamine and it kept them up through the night and into the next day. They had HFCs or HSCs that they had to conduct and they did them quickly and in a timely manner and they were given time off for it.
Q: All right. What was an HFC or an HSC? What are you talking about?
A: I wasn’t sure because I don’t have a maintenance background.
Q: Did you ask the accused?
A: I talked to him about it. I asked him what it was. Basically my recollection was that it had some sort of check or inspection they conducted on an aircraft.
Q: How was his methamphetamine use supposed to be related to this aircraft check?
A: Methamphetamine is a speed. Basically what it does is hype your system *220up so it makes you feel like you are always ready to go. By ingesting methamphetamine it makes you feel like you can accomplish anything and everything in a relatively quick time.
Q: What did the accused tell you it did for him with regard to this aircraft check?
A: It made him feel like he was up and constantly going so that they could conduct their work in a faster manner; it made them work faster basically.
Q: So he told you he was under the influence of methamphetamine when he was working on these aircraft?
A: That is true.
Q: The result of that aircraft work was what?
A: They conducted the inspection in a timely manner and they were given time off.
Q: After the 5th of July—Before I go further, let me—Did you discuss with the accused who he used methamphetamine with, I guess people do this together, on the 5th of July?
A: I did.
Q: How did that come about?
A: In the conversation Airman Maio told me that he basically used with his roommate, Airman Spencer, and that they liked to use it prior to going jet skiing on the weekends. He didn’t really particularly like partying with military people or they didn’t party with military people because, allegedly, a female had been apprehended by OSI and the female came back and told them that OSI knew about them, or had their names or something, so that they were real cautious with other military people.
* * * * * *
A: On the 23rd of June.
Hi j|c afc sjt $ *
Q: How did he use? With a key? The same way?
A: Right. Snorting through the nose.
Q: On a key?
A: Yes ma’am.
Q: So the accused told you that he primarily used the methamphetamine with Airman Spencer. Right?
A: That is correct.
Q: Did you ever see those two use together?
A: No ma’am.
Q: On the 5th of July when he was telling you he used methamphetamine primarily with Airman Spencer and about this using methamphetamine and working on these aircraft, let me ask you this. The date that the accused supposedly got cranked up on methamphetamine and worked on this aircraft, did he tell you when that was that he got this day—he did this and got the day off?
A: No. When he told me on the 5th of July, and his words were, “the week before” so it could have been anywhere from the last few days of June until the first few days of July.
Q: And he told you he was rewarded by getting time off?
A: Comp time.
Q: Did he say how much time?
A: I believe it was just that day.
Q: After the 5th of July 1989, did you ever see the accused involved with drugs?
A: One more time.
Q: When was this?
A: I’d have to check my statement to be sure of the date. But it was towards the mid month of July, probably around the 14th I would guess.
Q: Is the 14th of July your best recollection?
A: Off of memory.

. We have characterized the quantum of corroboration evidence required by Mil.R.Evid. 304(g), Manual for Courts-Martial, United States, 1984, as “slight” (United States v. Yeoman, 25 MJ 1, 4 (CMA 1987)), or "very slight” (United States v. Melvin, 26 MJ 145, 146 (CMA 1988)). This characterization reflects our understanding that it need not establish beyond a reasonable doubt or by a preponderance of the evidence the truth of the essential facts stated in the confession. See S. Saltzburg, L. Schinasi and D. Schlueter Military Rules of Evidence Manual, Editorial Comment on Rule 304(g) at 166 (3d ed.1991).
. Appellant's admissions to the undercover agent were made subsequent to his use of real methamphetamine but contemporaneous with and prior to his use of the placebo methamphetamines. A strong argument can be made that these spontaneous admissions do not require corroboration under Mil.R.Evid. 304(g). See United States v. Pennell, 737 F.2d 521, 537 (6th Cir.1984), cert. denied, 469 U.S. 1158, 105 S.Ct. 906, 83 L.Ed.2d 921 (1985). In any event, no objection was made by appellant to use of these admissions at the suppression hearing as cor*219roboration of his later confession. See Mil.R.Evid. 304(d)(2)(A).
. We again note that, at the suppression hearing, appellant did not object to introduction in evidence of his earlier admissions to Sergeant Brainard. See Mil.R.Evid. 304(c)(2) and (d)(2)(A). In view of the recent decision of Arizona v. Fulminante, — U.S.-,---, 111 S.Ct. 1246, 1257-66, 113 L.Ed.2d 302 (1991), if such evidence was admitted at trial, any error in admission of his later confession could be considered harmless. See RCM 910(a)(2), Manual, supra. Cf. United. States v. Wong Ching Hing, 867 F.2d 754, 758 (2d Cir.1989).
In Federal civilian practice it is inappropriate for a conditional guilty plea to be entered and accepted when the issue reserved for appeal will not be dispositive of an accused’s case. See United States v. Wong Ching Hing, supra. See generally 18 USC (Rule 11(a)(2)) Federal Rule of Criminal Procedure, Notes of Advisory Committee on 1983 Amendment.
