Guns, Cannabis, and the Second Amendment
The Supreme Court heard oral arguments on whether the federal prohibition on firearm possession by drug users violates the Second Amendment. The case centers on 18 U.S.C. § 922(g)(3), which makes it a felony for any “unlawful user of or addicted to any controlled substance” to possess a firearm.
The case carries outsized significance for Michigan, where recreational marijuana has been legal since 2018. Under current federal law, any Michigan resident who uses cannabis — even in full compliance with state law — is technically barred from owning or purchasing firearms.
A ruling striking down the provision could harmonize the tension between Michigan’s cannabis framework and federal firearms law. A ruling upholding it would perpetuate a legal gray zone affecting an estimated 2.5 million Michigan adults who have used marijuana in the past year.
