Linda Elaine Minor appeals her conviction, entered upon a written plea agreement, of distribution of cocaine base, in violation of 21 U.S.C. § 841 (2000). As part of her written plea agreement, Minor expressly waived her right to appeal her sentence, and acknowledged that drug weight was a factual matter to be determined by the district court, that the court could find her responsible for a higher or lower amount, and that such determination of drug weight by the district court was not a basis on which she could rely to seek to withdraw her plea. Following a proper Fed.R.Crim.P. 11 hearing, the district court accepted Minor’s plea and sentenced her to forty-six months’ imprisonment, three years of supervised release, and a $100 special assessment.

Minor claims on appeal that the district court erred in adopting the drug weight set forth in her presentence report, rather than that set out in her plea agreement. *423 As to this claim, we find that Minor knowingly and voluntarily waived her right to appeal. United States v. Marin, 961 F.2d 493, 496 (4th Cir. 1992).

We therefore dismiss Minor’s appeal. 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
