Marcus Plater seeks to appeal the district court’s order denying his motion filed under 28 U.S.C.A. § 2255 (West Supp. 2001). We have reviewed the record and the district court’s opinion and find no reversible error. To the extent that Plater challenges the constitutionality of 21 U.S.C.A. § 841(b) (West 1999 & Supp. 2001), this claim fails as we have upheld the constitutionality of § 841(b). United States v. McAllister, 272 F.3d 228 (4th Cir. 2001). Accordingly, we deny a certificate of appealability and dismiss the appeal on the reasoning of the district court. *104 United States v. Plater, Nos. CR-99-559; CA-01-1489 (D.Md. Jan. 18, 2002). We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before the court and argument would not aid the decisional process.

DISMISSED.
