Michael Richard Dempski, III, appeals the revocation of supervised release on his conviction for possession with intent to distribute marijuana. He seeks to challenge the constitutionality of 21 U.S.C. § 841(a) and (b) in light of Apprendi v. New Jersey, 530 U.S. 466, 120 S.Ct. 2348, 147 L.Ed.2d 435 (2000). Because a challenge under Apprendi is not jurisdictional, see United States v. Longoria, 298 F.3d 367, 372 (5th Cir. 2002) (en banc), Dempski may not present this claim in an appeal following the revocation of supervised release. See United States v. Teran, 98 F.3d 831, 833 n. 1 (5th Cir. 1996); see also United States v. Moody, 277 F.3d 719, 720-21 (5th Cir. 2001). Moreover, as Dempski concedes, his Apprendi argument is foreclosed by United States v. Slaughter, 238 F.3d 580, 582 (5th Cir. 2000).

Accordingly, the judgment of the district court is AFFIRMED.
