I. INTRODUCTION
A Jefferson Circuit Court jury found Appellant guilty of first degree trafficking in a controlled substance in violation of KRS 218A.1412. After the guilt/innocence phase verdict, Appellant waived jury sentencing. Pursuant to an agreement he negotiated with the Commonwealth, Appellant entered conditional guilty pleas which admitted that he was subject to penalty enhancement as both a KRS 218A.1412 “second or subsequent” offender and a second degree persistent felony offender under KRS 532.080(5). The trial court sentenced Appellant in accordance with the agreement to a thirty (30) year term of imprisonment. Appellant thus appeals to this Court as a matter of right.1
The single issue Appellant raises on appeal concerns the length of his sentence. Appellant argues that Gray v. Commonwealth2 holds that his underlying trafficking offense could be enhanced under either KRS Chapter 218A or KRS 532.080(5), but not both, because his two prior felony trafficking convictions stemmed from the same indictment and a single final judgment. Appellant thus contends that his underlying Class C felony conviction could be enhanced for sentencing purposes only to a Class B felony with a permissible penalty range of between ten (10) and twenty (20) years imprisonment. Appellant argues that his thirty (30) year sentence falls outside the permissible penalty range.
II. ANALYSIS
Although Appellant correctly notes that this Court reversed and remanded a similarly situated matter in Gray, “the doctrine of stare decisis does not commit us to the sanctification of ancient [or relatively recent] fallacy.”3 While we recognize this Court should decide cases “with a respect for precedent,” 4 this respect does not “require blind imitation of the past”5 or unquestioned acceptance ad infinitum. Rather, in many ways, respect for precedent demands proper reconsideration when we find sound legal reasons to question the correctness of our prior analysis. After careful reconsideration of the Gray holding, we find that Gray both misinterpreted the primary authority upon which it relied and overlooked the separate provisions governing and policies *560underlying KRS Chapter 218A “second or subsequent offense” enhancement. Accordingly, we overrule Gray v. Commonwealth and hold that a defendant with two prior convictions for first degree trafficking in a controlled substance who is again convicted under that section can be sentenced within the penalty range for Class A felonies (“not less than twenty (20) years nor more than fifty (50) years, or life imprisonment”),6 regardless of whether the sentences for the prior convictions were ordered to run concurrently within the same judgment. Such an offender is eligible for penalty enhancement as both a KRS Chapter 218Á “second or subsequent” offender and as a second degree persistent felony offender. As Appellant appears to fit this profile,7 we find that the trial court sentenced him appropriately and affirm the judgment of the Jefferson Circuit Court.
One of the ways in which the General Assembly has sought to deter drug crimes is by establishing more serious penalties for repeat offenders of the Kentucky Controlled Substances Act.8 Thus, KRS 218A.1412(2)(b) directs that a defendant convicted of a “second or subsequent offense” of first degree trafficking in a controlled substance will receive a penalty within the Class B felony penalty range of between ten (10) to twenty (20) years imprisonment.9 KRS 218A.010(25) broadly defines “second or subsequent offense” to include a conviction at any prior time in any jurisdiction:
“Second or subsequent offense” means that for the purposes of this chapter an offense is considered as a second or subsequent offense, if, prior to his conviction of the offense, the offender has at any time been convicted under this chapter, or under any statute of the United States, or of any state relating to substances classified as controlled substances or counterfeit substances, except that a prior conviction for a nontraffick-ing offense shall be treated as a prior offense only when the subsequent offense is a nontrafficking offense....10
Within the Kentucky Penal Code, the General Assembly has established sentencing enhancement procedures for persistent felony offenders which authorize judges and juries to punish more severely those individuals who continue to commit felony crimes. KRS 532.080(2) outlines the elements for second degree persistent felony offender status11 and KRS 532.080(5) au*561thorizes trial courts to impose enhanced sentences upon such offenders: *562While misdemeanor controlled substance offenses can lead to felony penalty enhancement under the Kentucky Controlled Substances Act,18 only crimes for which “a sentence to a term of imprisonment of one (1) year or more or a sentence to death was imposed” 19 will allow PFO enhancement. The broader range of cases in which penalty enhancement is available under KRS Chapter 218A demonstrates the General Assembly’s intent to deal more harshly with repeat controlled substance offenders.
*561A person who is found to be a persistent felony offender in the second degree shall be sentenced to an indeterminate term of imprisonment pursuant to the sentencing provisions of KRS 532.060(2) for the next highest degree than the offense for which convicted. A person who is found to be a persistent felony offender in the second degree shall not be eligible for probation, shock probation, or conditional discharge, unless all offenses for which the person stands convicted are Class D felony offenses which do not involve a violent act against a person, in which case probation, shock probation, or conditional discharge may be granted. A violent offender who is found to be a persistent felony offender in the second degree shall not be eligible for parole except as provided in KRS 439.3401.12
Differences between the two enhancement provisions indicate that the General Assembly had different purposes in mind for each. While KRS Chapter 218A contains no limit upon either the age at which a defendant may be subject to the “second or subsequent offense” enhancement or how old a defendant must be before a prior KRS Chapter 218A conviction can constitute a “second or subsequent offense,” persistent felony offenders must be at least twenty-one (21) years old13 and only those felony crimes committed after a defendant’s eighteenth (18th) birthday can qualify as a previous felony conviction.14 The age limitations in KRS 532.080 reserve PFO enhancement for more mature offenders who have failed previous attempts at rehabilitation.15 While a defendant may be subject to KRS Chapter 218A penalty enhancement regardless of when the prior offense was committed,16 KRS 532.080 exempts certain remote convictions from its definition of a previous felony conviction.17
*562Certainly, if Appellant had entered a guilty plea to only one count of first degree trafficking in a controlled substance, statutory and constitutional protections against double jeopardy would prevent the Commonwealth from using the one prior conviction for both Chapter 218A “second or subsequent offense” enhancement and for PFO enhancement.20 However, in this case, the August 1992 judgment reflects that Appellant entered pleas of guilty to two counts of first degree trafficking in a controlled substance. In Gray, this Court addressed a factual situation virtually identical to the one now before this Court and reached the conclusion that enhancement under both Chapter 218A and KRS 582.080 was improper because KRS 532.080(4) “requires merger of appellant’s prior convictions for PFO purposes, and ... these merged convictions cannot subsequently be divided for further enhancement purposes.”21 Upon reconsideration, we conclude that our analysis of this issue in Gray was incorrect.
In an “effort to avoid the label of persistent felony offender for persons who might be rehabilitated through an ordinary term of imprisonment for the offense most recently committed,”22 KRS 582.080(4) provides that:
For the purpose of determining whether a person has two (2) or more previous felony convictions, two (2) or more convictions of a crime.for which that person served concurrent or uninterrupted consecutive terms of imprisonment shall be deemed to be only one (1) conviction, unless one (1) of the convictions was for an offense committed while that person was imprisoned.23
This subsection unquestionably deems Appellant’s two felony convictions for first degree trafficking in a controlled substance to be one conviction “for the purpose of determining whether a person has two (2) or more previous felony convictions” — in other words, for the purpose of determining whether Appellant is a first degree persistent felony offender.24 KRS 532.080(4), however, does not affect whether Appellant is subject to KRS Chapter 218A enhancement as a “second or subsequent” offender because KRS Chapter 218A’s definition of “second or subsequent offense” includes offenders who have “at any time been convicted under this chapters.” 25
*563Gray relied almost exclusively upon its belief that Howard v. Commonwealth26 implicitly held, without actually stating, that KRS 532.080(4)’s “merger” of felony convictions is irreversible.27 However, both Gray’s premise and its conclusion were faulty — Howard contains no such holding, express or implied, and KRS Chapter 218A penalty enhancement always precedes PFO enhancement.28
In Howard, the appellant had been convicted in 1980 of a felony offense and, in 1983, of two felony offenses and a misdemeanor KRS Chapter 218A offense.29 In 1988, Howard entered a conditional guilty plea to: (1) a new indictment for the felony offense of “second or subsequent” trafficking in a controlled substance which relied upon the prior 1983 misdemeanor conviction, and (2) being a first degree persistent felony offender.30 On appeal, Howard argued that “since the sentences were run concurrently, all of his 1983 convictions merged for PFO purposes, and could not later be ‘split’ by the Commonwealth to obtain both PFO 1 and subsequent offender convictions.”31 This Court affirmed the trial court and emphasized that the KRS 532.080(4) “merger” occurs only for PFO purposes:
We believe the appellant is, proverbially speaking, comparing apples to oranges. The 1983 sentences merged, but the 1983 convictions, except the felonies for PFO purposes, did not. Appellant was convicted of a felony in 1980 and, in 1983, after being convicted of two felonies whose sentences were run concurrently, for purposes of being adjudicated a PFO 1, was convicted of one more felony. Those two felony convictions, along with the 1988 felony conviction, gave him the minimum number of felonies (three) to be convicted as a PFO 1. The 1983 felony convictions were merged for purposes of the PFO statute. The 1983 drug misdemeanor conviction, on the other hand, never merged with the 1983 felony convictions for any purpose, always stood alone, and was independently used to obtain the subsequent offender conviction.32
The Gray Court apparently felt that the Howard Court’s holding turned on the fact that Howard’s previous KRS Chapter *564218A conviction was a misdemeanor and believed that the Court would have reached a different result if that prior conviction had been a felony.33 The language of the opinion, however, contradicts that inference. The Howard Court recognized that the so-called “merger” provision contained at KRS 532.080(4) states only that felony convictions served concurrently or consecutively without interruption are counted as one prior conviction for PFO purposes. The alleged “implicit” holding is nowhere to be found, and, to the extent Gray rests upon this non-existent holding, we must overrule it.
III. CONCLUSION
Because Appellant’s prior criminal record contains two convictions for first degree trafficking in a controlled substance, the trial court properly sentenced him in accordance with both the KRS 218A.1412 “second or subsequent offense” enhancement and the KRS 532.080(5), second degree PFO enhancement. We therefore affirm the judgment of the Jefferson Circuit Court.

. Because Appellant entered his conditional guilty plea to the enhancement provisions before the Commonwealth introduced its evidence during the PFO/Truth-in-Sentencing phase, the record in this case is somewhat incomplete. However, the post-conviction pleadings, as well as the parties' agreement regarding the nature of the prior convictions, allow us to reach the merits of Appellant's argument. We believe the better practice would be for defendants to enter into a stipulation as to the material facts prior to the conditional guilty plea.

Although not stated directly, the holding in Howard implies that, once felony convictions are merged for PFO purposes, the convictions cannot then be split and used as the basis for further enhancement. An independent conviction is thus needed for subsequent drug offender enhancement. In other words, once felony convictions are merged for purposes of the PFO statute, then the convictions must remain merged. Once the PFO statute is applied, the statute and all its provisions must remain in force.
Id.
. The Gray Court’s belief that “once felony convictions are merged for PFO purposes, the convictions cannot then be split and used as the basis for further enhancement” ignores the fact that KRS Chapter 218A "second or subsequent offender” enhancement will precede PFO enhancement and any KRS 532.080(4) “merger” will occur only after the factfinder sets a penalty on the repeat trafficking offense. See KRS 532.080(1); 1 Cooper, Kentucky Instructions to Juries (Criminal) § 12.25, Commentary (1999); Id. at § 12.35A; Commonwealth v. Reneer, Ky., 734 S.W.2d 794 (1987). As Chapter 218A "second or subsequent offense” enhancement is not "subsequent” to PFO enhancement, Gray relies upon a chronological error.
