Following a jury trial, Neville A. Hutchinson was convicted on one count of conspiracy to possess with intent to distribute and to distribute 100 kilograms or more of marijuana, in violation of 21 U.S.C. § 846 (1994). * Hutchinson asserts that the district court erred by denying his motion for judgment of acquittal because the evidence *831 was insufficient to convict him in that the government’s witnesses lacked credibility. However, in evaluating the sufficiency of the evidence, this court does not review the credibility of the witnesses and assumes that the jury resolved all contradictions in the testimony in favor of the government. Glasser v. United States, 815 U.S. 60, 80, 62 S.Ct. 457, 86 L.Ed. 680 (1942); United States v. Romer, 148 F.3d 359, 364 (4th Cir. 1998). Accordingly, we affirm Hutchinson’s conviction. 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.

AFFIRMED.
