Pursuant to his guilty plea, Ramon Lee Thompson was convicted of possession of a firearm by a convicted felon, in violation of 18 U.S.C.A. §§ 922(g)(1), 924 (West 2000 & Supp. 2005), and conspiracy to make false statements in connection with the acquisition of firearms, in violation of 18 U.S.C.A. § 922(a)(6), 371 (West 2000 & Supp. 2005). The district court sentenced Thompson to concurrent terms of fifty-two months in prison on each offense. Thompson timely appeals his sentence, contending that the district court erred by denying his request for a two-level downward adjustment under U.S. Sentencing Guidelines Manual (USSG) § 3E1.1 (2004) for acceptance of responsibility. We affirm Thompson’s sentence.

The district court determined that a downward adjustment for acceptance of responsibility was not warranted because Thompson tested positive for marijuana use while he was on release pending sentencing. We find no clear error in this ruling. See USSG § 3E1.1, cmt. (n.l(b)); United States v. Rise, 369 F.3d 766, 771 (4th Cir. 2004) (providing standard); United States v. Ceccarani, 98 F.3d 126, 130-31 (3d Cir. 1996) (upholding denial of acceptance of responsibility reduction based on new unrelated criminal conduct).

Accordingly, we affirm Thompson’s sentence. 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.
