If you use recreational marijuana, you cannot legally carry a concealed firearm anywhere in the United States, even in a state where both cannabis and concealed carry are legal. Federal law treats any marijuana user as a “prohibited person” who cannot possess a gun or ammunition, and a state-issued concealed carry permit does nothing to change that. Combining the two is a federal felony as of now, though a Supreme Court decision expected in summer 2026 could change the rules.
Your State Permit Doesn’t Override Federal Law
State agencies issue concealed carry permits under state law. Federal firearms law is separate, and where the two conflict, federal law wins. On this question, they conflict head-on.
Under 18 USC 922, anyone who is an unlawful user of a controlled substance is barred from possessing a firearm or ammunition.1Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts Marijuana is still a Schedule I controlled substance federally, so any use qualifies as unlawful — regardless of state legalization, regardless of whether you bought it at a licensed dispensary. Your state permit governs only the state-law question of whether you can carry concealed. It says nothing about the federal prohibited-person status that attaches to you the moment you use cannabis.
So the practical situation is this: a recreational marijuana user with a valid state concealed carry permit is violating federal law every time they carry, even if their conduct is fully compliant with state cannabis and firearms rules.
How Much Use Triggers the Prohibition
Not every past encounter with marijuana turns you into a prohibited person. The ATF issued an interim final rule on January 22, 2026 revising the definition of “unlawful user.”2Federal Register. Revising Definition of Unlawful User of or Addicted to Controlled Substance
Under the new definition, an unlawful user is someone who regularly uses a controlled substance over an extended period continuing into the present. The rule explicitly excludes isolated or sporadic use. The government must show sufficient regularity and recency to indicate ongoing conduct, and a single positive drug test or a lone possession arrest no longer automatically qualifies.2Federal Register. Revising Definition of Unlawful User of or Addicted to Controlled Substance
The catch: anyone using cannabis on any regular basis, even once or twice a week, comfortably meets the “regular and recent” standard. The revision helps people with distant or one-off use. It does not carve out regular recreational users. The comment period runs through June 30, 2026, after which the ATF will finalize the rule.
What You’re Risking If You Carry Anyway
Possessing a firearm while being an unlawful user of a controlled substance is a federal felony punishable by up to 15 years in prison and a fine of up to $250,000.3Office of the Law Revision Counsel. 18 USC 924 – Penalties4Office of the Law Revision Counsel. 18 USC 3571 – Sentence of Fine That exposure applies to carrying a concealed handgun the same way it applies to any other form of possession.
Federal prosecutors bring roughly 300 cases per year where the drug-user firearm ban is the leading charge. Enforcement isn’t chasing every recreational user, but it isn’t theoretical either.
Buying the Firearm in the First Place
Anyone planning to concealed carry has to acquire the firearm somewhere, and that raises a second problem. Every buyer at a licensed dealer completes ATF Form 4473. Question 21.f asks whether you are an unlawful user of or addicted to marijuana or any other controlled substance. Directly below the question, in bold, the form states: “The use or possession of marijuana remains unlawful under Federal law regardless of whether it has been legalized or decriminalized for medicinal or recreational purposes in the state where you reside.”5Bureau of Alcohol, Tobacco, Firearms and Explosives. Firearms Transaction Record – ATF Form 4473
The answers box you in. Answering yes stops the sale. Answering no while you’re a regular user is a separate federal felony — making a false statement on the form carries up to five years in prison, on top of the possession charge.3Office of the Law Revision Counsel. 18 USC 924 – Penalties In a prosecution stemming from a purchase, both charges can be brought together.
Rescheduling Probably Won’t Fix This for Recreational Users
A common assumption is that moving marijuana from Schedule I to Schedule III would clear up the gun question. For recreational use, it wouldn’t.
The federal firearms ban applies to unlawful users of any controlled substance. Schedule III drugs are still controlled substances. What changes at Schedule III is that a drug can be prescribed through the pharmaceutical system, so someone using it with a valid prescription is arguably no longer an unlawful user. Recreational users have no prescription. Using a Schedule III drug without one remains unlawful, so the firearms prohibition stays in place.1Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts
The rescheduling process itself is still working through the system. The Department of Justice published a proposed rule in May 2024 to move marijuana to Schedule III.6Federal Register. Schedules of Controlled Substances: Rescheduling of Marijuana A DEA administrative hearing was postponed in January 2025 pending an appeal.7Drug Enforcement Administration. Hearing on the Proposed Rescheduling of Marijuana Postponed In December 2025, President Trump signed an executive order directing the Attorney General to complete the rulemaking “in the most expeditious manner.”8The White House. Increasing Medical Marijuana and Cannabidiol Research Even when it finishes, recreational users should not expect a change in their firearms status.
The Supreme Court Case That Could Change Everything
The real development to watch is at the Supreme Court. The Court heard oral arguments in United States v. Hemani on March 2, 2026, in a challenge to the constitutionality of the federal ban on drug users possessing firearms. Early reporting indicated the justices were skeptical of the government’s position. A decision is expected by summer 2026.
The core question is whether a law that permanently disarms someone based on their status as a drug user, without any requirement that they were intoxicated while holding the firearm, fits within the historical tradition of firearms regulation the Second Amendment permits. The Fifth Circuit already ruled in United States v. Daniels that the ban was unconstitutional as applied to a marijuana user, finding that historical intoxication laws restricted carrying weapons only while actually drunk rather than permanently disarming someone based on other-time consumption. The government’s petition for Supreme Court review in that case remains pending.
If the Court strikes down or narrows the ban in Hemani, the answer to whether a recreational marijuana user can concealed carry could look very different by the end of 2026. Until then, the answer under federal law is no.
