United States v. Blair Cook

Rovner, Circuit Judge.

*548 A jury convicted Blair Cook of being an unlawful user of a controlled substance (marijuana) in possession of a firearm. See 18 U.S.C. § 922 (g)(3). Cook appeals his conviction, contending that the statute underlying his conviction is facially vague, that it improperly limits his Second Amendment right to possess a firearm, and that the district court did not properly instruct the jury as to who constitutes an unlawful user of a controlled substance. We affirm Cook's conviction.
