Appealing the Judgment in a Criminal Case, Johnny S. Estrada, Jr., raises arguments that are foreclosed by United States v. Gamez-Gonzalez, 319 F.3d 695, 699-700 (5th Cir. 2003), which held that knowledge of the drug type is not a material element of the offense under 21 U.S.C. § 841, and *287 by United States v. Valencia-Gonzales, 172 F.3d 344, 345-46 (5th Cir. 1999), which held that the defendant may be sentenced under the guidelines according to the drug he was carrying rather than the drug he believed he was carrying. The Government’s motion for summary affirmance is GRANTED, and the judgment of the district court is AFFIRMED.
