Douglas Christopher Jones appeals the sentence he received after he pleaded guilty to possession of more than five grams of cocaine base with intent to distribute and the intentional use of a minor to avoid detection. Because Jones fails to show that he would have received a different sentence under Guidelines that were only advisory, he fails to establish plain error under United States v. Booker, -U.S.-, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005). See United States v. Valenzuela-Quevedo, 407 F.3d 728, 733-34 (5th Cir. 2005), petition for cert. filed (July 25, 2005) (No. 05-5556). Further, given that Jones twice tested positive for drug use subsequent to his arrest, he fails to show that the district court clearly erred when it denied an adjustment for acceptance of responsibility. See United States v. Villanueva, 408 F.3d 193, 203 & n. 9, (5th Cir. 2005), petition for cert. filed (July 26, 2005) (No. 05-5580); United States v. Flucas, 99 F.3d 177, 180 (5th Cir. 1996); U.S.S.G. § 3E1.1, comment. (nn.1(B), 3, and 5).

AFFIRMED.
