OPINION
Johnny Craig Harp appeals his sentence for using a dangerous weapon in committing a bank robbery. See 18 U.S.C.A. § 2113(d) (West 2000). We affirm.
I.
Harp pleaded guilty to the offense of conviсtion pursuant to a written plea agreement. The presentence report placed Harp’s base offense level at 20. See United States Sentencing Guidelines Manual § 2B3.1(a) (2002). Harp received a two-level enhancement under § 2B3.1(b)(l) because the property of a financial institution was taken, and a three-level enhancement under § 2B3.1(b)(2)(E) because he possessed a dangerous weapon during the commission of the robbery. Additionally, because Harp had previously been convicted of rob *245 bery with a dangerous weapon and felonious possession with the intent to distribute marijuana, he was designated a career offender, and his offense level was increased to 34. See U.S.S.G. § 4B1.1. The district court reduced this оffense level by three levels for acceptance of responsibility, see U.S.S.G. § 3E1.1, resulting in a total offense level of 31. Because of the career offender designation, Harp’s Criminal History Category was VI, see U.S.S.G. § 4Bl.l(b), producing a guideline range of 188-235 months. On the Government’s motion, the district court departed downward to account for Harp’s substantial assistance in the prosecution of his codefen-dant, see U.S.S.G. § 5K1.1, p.s., sentencing Harp to 128 months’ imprisonment.
II.
Harp maintains that thе district court erred in concluding that he met the requirements for designation as a career offender. Because Harp raises this claim for the first time on appeal, we review for plain error.
See
Fed.R.Crim.P. 52(b);
United States v. Olano,
For Harp to be designated a career offender, the Government must establish (1) that Harp was at least 18 at the time of thе instant offense, (2) that the instant offense is a felony that is either a “crime of violence” or a “controlled substance offense,” and (3) that Harp had at least two prior felony convictions for either a “crime of violеnce” or a “controlled substance offense.” U.S.S.G. § 4B1.1(a). Harp concedes that the Government established the first two requirements, but he argues that one of his prior convictions considered by the district court — a July 16, 2001 North Carolina сonviction for possession with the intent to distribute marijuana — was not a “controlled substance offense” because it was not “punishable by imprisonment for a term exceeding one year.” U.S.S.G. § 4B1.2(b).
1
To determine whether a convictiоn is for a crime punishable by a term of imprisonment exceeding one year, we consider the law in effect at the time of the conviction.
See United States v. Johnson,
Harp mаintains that because the specific facts of his case did not provide any basis for imposition of a sentence exceeding one year, his prior conviction was not for an offense punishable by a term of imprisonment of more than one year. He explains that although the maximum aggravated punishment for possession with the intent to distribute marijuana, a Class I felony, is 15 months, the maximum non-aggravated punishment is only 12 months.
See
N.C. Gen.Stat. § 15A-1340.17(c), (d) (LexisNexis 2003). But this court has already rejected such an individualized analysis in
United States v. Jones, 195
F.3d 205 (4th Cir.1999), in construing statutory language essentially identical to the language of § 4B1.2(b). In
Jones,
we held, in the context of a felon-in-possession-of-firearm conviction,
see
18 U.S.C.A. § 922(g)(1) (West 2000), that a prior North Carolina cоnviction was for “a crime punishable by imprisonment for a term exceeding one year,”
id.,
if
any
defendant charged with that crime could receive a sentence of more than one year.
See Jones,
[I]n § 922(g)(1), “punishable” is an adjective used tо describe “crime.” As such, it is more closely linked to the conduct, the crime, than it is to the individual convicted of the conduct. Congress could have written § 922(g)(1) differently had it intended to focus on the individual in particular rather than the crime fоr which the individual was convicted. Instead of the phrase, “individual convicted ... of a crime punishable by imprisonment for a term exceeding one year,” Congress could have used the phrase, “individual punished by imprisonment for a term excеeding one year” or even “individual sentenced for imprisonment for a term exceeding one year.”
Id. at 207 (internal quotation marks omitted) (alterations in original). Thus, to determine whether a conviction is for a crime punishable by a prison term exceeding one year, Jones dictates that we consider the maximum aggravated sentence that could bе imposed for that crime upon a defendant with the worst possible criminal history. See id. at 206-08.
Harp contends that this analysis is no longer appropriate because, in light of
Blakely v. Washington,
— U.S. -,
III.
Harp also argues that his constitutional rights were violated when the district court determined that he was a career offender without the elements of that designation having been charged in an indictment.
3
Because this allegation of error also was not prеserved in the district court, we again review for plain error. We need not determine whether the district court plainly erred in this manner and affected Harp’s substantial rights in so doing, because even if it did, we would not exercise our discretion to notice the error.
See United States v. Cotton,
IV.
Harp finally maintains that even if the district court did not err in designating him a career offender, it errеd in failing to *248 treat the guidelines as advisory. As with Harp’s other claims, we review for plain error because Harp did not raise this issue in the district court. We conclude that Harp has not satisfied the plain error requirements.
Although the failurе to treat the guidelines as advisory was plain error,
4
Harp has not demonstrated that it affected his substantial rights.
See United States v. White,
V.
For the foregoing reasons, we find no reversible error and therefore affirm Harp’s sentence.
AFFIRMED
Notes
. Section 4B 1.2(b) provides in full that
[t]he term 'controlled substance offense' means an offense under federal or state law, punishable by imprisonment for a term exceeding one year, that prohibits the manufacture, import, export, distribution, or dispensing of a controllеd substance (or a counterfeit substance) or the possession of a controlled substance (or a counterfeit substance) with intent to manufacture, import, export, distribute, or dispense.
. At the time of Harp's conviction, fаcts warranting an aggravated sentence were not required to be included in the indictment and found by a jury beyond a reasonable doubt. Prior to
Blakely,
the North Carolina Supreme Court had held that the "statutory maximum” for crimes under its structured sentеncing regime was the highest sentence authorized for the crime charged
assuming the highest theoretical criminal history and the aggravated punishment. See State v. Lucas,
. Harp does not challenge the constitutionality of the two-level enhancement he received because property of a financial institution was taken, see U.S.S.G. § 2B3.1(b)(1), or the three-level enhancement imposed because he possessed a dangerous weapon during the commission of the robbery, see U.S.S.G. § 2B3.1(b)(2)(E). Such a challenge would have been fruitless in any event. Even assuming that the district court plainly erred in imposing those enhancements, their imposition did not affect Harp's substantial rights because it resulted in an offеnse level of 25. The career offender designation, see U.S.S.G. § 4B1.1, which did not rely on these enhancements, and the acceptance of responsibility reduction, see U.S.S.G. § 3E1.1, produced a total offense level of 31 — from which the district court departed downward to account for Harp's substantial assistance, see U.S.S.G. § 5K1.1.
. We of course offer no criticism of the district judge, who followed the law and procedure in effect at the time of Harp’s sentencing.
. Harp also raises challenges in a pro se supplemental brief. We have carefully considered these allegations of error and find them to be without merit.
