Appealing the judgment in a criminal case, Raaf Atrach raises an argument that he concedes is foreclosed by United States v. Betancourt, 586 F.3d 303, 308-09 (5th Cir. 2009), which held that knowledge of drug type and quantity is not an element of the offense under 21 U.S.C. § 841. The appellant’s motion for summary disposition *294 is GRANTED, and the judgment of the district court is AFFIRMED.
