Veterans Day is a good moment for an honest look at veterans and cannabis. Many veterans have practical questions. Will cannabis affect VA benefits? Can a VA doctor help with a Michigan medical card? What does research say about PTSD? This guide covers VA policy, federal limits, Michigan's program and where to find support. If you're in crisis right now, call the Veterans Crisis Line: dial 988, then press 1.
Why veterans and cannabis belong in the Veterans Day conversation
Cannabis use among veterans has grown. According to VA's National Center for PTSD, 9.8% of U.S. veterans reported using cannabis in the past year in 2019. Some use it to try to relieve PTSD symptoms, and several states specifically approve medical cannabis for PTSD. Clear, accurate information is one way to honor that service. This guide is educational, not medical advice.
Veterans in cannabis advocacy
Veterans have been among the strongest voices asking for real research. The first randomized, placebo-controlled trial of smoked cannabis for PTSD, published in 2021, enrolled military veterans. Its authors wrote that demand for that research had largely been driven by veteran advocacy groups.
Michigan has put money behind that research, too. Through the state's Veteran Marijuana Research grant program, Wayne State University received a five-year, $7 million award in 2021 to study cannabinoids, PTSD and depressive symptoms in veterans. Studies like this take years, and they're built to answer questions, not to promise results.
VA medical marijuana policy: what VA allows
VA's guidance, set out in VHA Directive 1315, comes down to four points:
- You can talk about it. VA encourages you to discuss cannabis use with your providers, who will note it in your VA medical record.
- Your benefits aren't at stake. VA says veterans won't be denied VA benefits because of marijuana use, and joining a state program doesn't affect eligibility for VA care.
- VA won't recommend it or sign forms. VA clinicians may not recommend medical marijuana or complete state program paperwork.
- VA won't provide or pay for it. VA pharmacies can't fill medical marijuana prescriptions, and VA won't pay for it from any source.
VA's guidance page was last updated in August 2023, and it still read this way in October 2026. That's despite an April 2026 federal regulation that moved marijuana covered by a state medical license into Schedule III, so ask your VA care team whether anything has changed.
Federal limits: VA grounds, federal jobs and firearms
Michigan law doesn't follow you everywhere.
- VA grounds. Using or possessing marijuana is prohibited at all VA medical centers, locations and grounds, because federal law is in force there.
- Federal jobs. Veterans who work for VA are subject to drug testing. If you work for another federal agency, check its drug-free workplace policy.
- Firearms. Federal law restricts gun possession by people who unlawfully use controlled substances, and federal law still lists cannabis as one. In a narrow June 2026 ruling, the Supreme Court held that prosecuting one regular marijuana user under that law violated the Second Amendment. The law itself still stands as of October 2026, so if you have a firearm or plan to buy one, ask a lawyer how it applies to you.
- Still serving. Active-duty, Guard and Reserve members follow military policy, whatever Michigan allows. Defense Department policy bars service members, including the Reserve Components, from using products that contain hemp, CBD included. Check with your command before using any cannabis or hemp product.
Michigan medical card and PTSD
Michigan's medical marijuana program lists PTSD among its qualifying conditions, alongside conditions such as chronic pain and cancer. If you're weighing a Michigan medical card for PTSD, remember that VA clinicians can't complete state program paperwork, so plan on working with a physician outside VA. Our step-by-step card page explains the application, and our patient guide covers life as a cardholder. To see what a card changes, read about Michigan medical card benefits.
A card doesn't change federal law or VA's policies, and it isn't a recommendation. Whether cannabis fits your situation is a conversation for you and your clinicians. For the wider legal picture, our Michigan law guide lays out the state's rules.
Cannabis and PTSD research: mixed and early
So far, the evidence is limited and mostly not encouraging:
- The trial. In the 2021 study, 80 veterans with PTSD smoked one of three cannabis preparations or a placebo for three weeks. Every group improved, and no cannabis version beat placebo.
- Reviews. VA's National Center for PTSD says research to date does not support cannabis as an effective PTSD therapy. It adds that chronic use might worsen trauma-related symptoms over time.
- Clinical guidance. The 2023 VA/DoD PTSD guideline strongly recommends against using cannabis or cannabis derivatives for PTSD, citing a lack of evidence, known side effects and risks.
- Risks. In one national study, about 12% of veterans with PTSD had a current cannabis use disorder. In another, cannabis use at the start of PTSD treatment was linked to double the risk of dropping out.
For people living with both PTSD and a substance use problem, VA's research summary points to a meta-analysis of four trials. Trauma-focused therapies worked better than non-trauma-focused ones, whether or not people used cannabis. For a wider look at the research, see cannabis benefits and risks. Please don't stop or swap a prescribed medication on your own; talk with your clinician first.
Support for veterans
You don't have to sort any of this out alone.
- Veterans Crisis Line: dial 988 and press 1, text 838255 or chat online, confidentially.
- Your VA care team: VA says talking about cannabis use won't cost you benefits.
- Michigan resources: our guide to supporting Michigan veterans lists state and national help.
To everyone who has served: thank you. In Michigan, adult-use cannabis is for those 21 and older, and registered patients 18 and older can buy with their card. If you choose to use it, enjoy it responsibly, and don't travel across state lines with cannabis.
