Larry Whitfield appeals from the district court’s judgment revoking his supervised release and imposing a forty-six-month sentence. Whitfield argues that the district court erred in concluding that he violated the terms of his supervised release by distributing marijuana. He contends that there was not a preponderance of the evidence demonstrating that the substance was marijuana, and even if it *201 was marijuana, that Whitfield was involved in distribution, instead of mere possession.

We review for an abuse of discretion a district court’s judgment revoking supervised release and imposing a term of imprisonment. United States v. Pregent, 190 F.3d 279, 282 (4th Cir. 1999); United States v. Copley, 978 F.2d 829, 831 (4th Cir. 1992). The district court need only find a violation of a condition of supervised release by a preponderance of the evidence. 18 U.S.C. § 3583(e)(3) (2012); Copley, 978 F.2d at 831. In this case, we conclude that the revocation did not amount to an abuse of discretion, because Whitfield’s confession to distribution and possession of marijuana was corroborated by the evidence of distribution found at his house, including a digital scale and baggies. Although the substance found in Whitfield’s residence was not analyzed by a laboratory, the officers testified that, based on their experience and training, the substance looked and smelled like marijuana and was stored in a suspicious place in the kitchen. We therefore conclude that the court did not clearly err in finding a Class A felony.

We affirm the judgment. We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before this court and argument would not aid the decisional process.

AFFIRMED.
