Cannabis and Firearms: A Legal Guide for Gun Owners

By Ty McDuffey J.D.

Forty million Americans use cannabis. Eighty million Americans own firearms. Under federal law, those two groups cannot overlap. Under state law in 24 states, they can.

The Supreme Court is resolving this tension right now. United States v. Hemani was argued March 2, 2026. A decision is expected by the end of June. Whatever the Court rules will reshape the law for every cannabis user who owns a gun and every gun owner considering cannabis.

This book is the current, comprehensive, easy-to-read guide to cannabis law as it stands in 2026. Written by a Missouri J.D. who writes professionally about the law, this guide covers the federal prohibition under 18 U.S.C. 922(g)(3), the ATF Form 4473 perjury trap, the constitutional battle from Bruen to Rahimi to Hemani, the Trump administration's Executive Order 14206 and the ATF's January 2026 Interim Final Rule, and the state-by-state landscape covering 18 priority cannabis-legal states in depth.

The book walks through these scenarios: medical cardholders, recreational users, hunters, concealed carry permit holders, veterans with VA recommendations, federal contractors, and cannabis industry workers from dispensary staff to armed security. It covers practical risk mitigation including NFA trusts, storage strategies, and the cessation pathway under the new ATF rule. It also covers what to do if you get charged, from the first 48 hours through Fourth and Second Amendment defenses.

2026 Edition. Information current as of April 2026. A post-Hemani second edition will follow the Supreme Court's decision.
