Juan Hernandez was convicted of one charge of conspiracy to possess more than five kilograms of cocaine with intent to distribute and sentenced to serve 144 months in prison and a five-year term of supervised release. Hernandez argues on appeal that the district court erred by denying his request for an adjustment to his sentence based on his allegedly minor *307 role in the offense and that 21 U.S.C. § 841(a),(b) is unconstitutional under Apprendi v. New Jersey, 530 U.S. 466, 120 S.Ct. 2348,147 L.Ed.2d 435 (2000).

Hernandez contends that he was significantly less culpable than other participants in the underlying offense and that he should have received a corresponding reduction to his sentence. The district court’s conclusion that Hernandez was not entitled to this adjustment is plausible in light of the record as a whole. See United States v. Villanueva, 408 F.3d 193, 203 & n. 9 (5th Cir.), cert, denied, — U.S.-, 126 S.Ct. 268, 163 L.Ed.2d 241 (2005). Consequently, Hernandez has not shown that he should receive relief on this issue. Hernandez’s contention that § 841 is unconstitutional is, as he concedes, foreclosed. See United States v. Slaughter, 238 F.3d 580 (5th Cir. 2000).

Hernandez has shown no error in the district court’s judgment. Consequently, that judgment is AFFIRMED.
