Defendant's conviction for knowingly possessing a firearm in and affecting commerce while being an unlawful user or addicted to a controlled substance is affirmed where: 1) the district court did not abuse its discretion in declining to instruct the jury on defendant's proposed definition of "unlawful user"; 2) the district court's instruction made clear that the prosecutor was required to prove more than use of a controlled substance in a manner other than as prescribed by a licensed physician; and 3) reasonable jurors could have concluded from this evidence that defendant's use of crack cocaine was regular, sustained, and contemporaneous with his possession of the five firearms at issue.
