Cannabis is legally sold for medical or recreational use in most US states, but one of the largest single healthcare providers to Americans who might benefit from it can't touch it: the Department of Veterans Affairs. The reason isn't policy reluctance so much as a structural fact about how American federalism works — and it leaves millions of veterans navigating two legal systems that don't agree with each other.
A Federal Agency in a State-by-State System
US cannabis law is a patchwork of individual state decisions. A state legalizing medical or recreational cannabis only changes what that state's own law enforcement will prosecute; it does not change federal law. Under the federal Controlled Substances Act, cannabis was classified for decades as a Schedule I substance — the same category as heroin, legally defined as having no accepted medical use and a high potential for abuse — regardless of what any individual state decided.
The VA is a federal agency, run under federal law, with facilities, staff, and funding that all fall under federal jurisdiction. State cannabis laws simply do not apply inside VA hospitals or clinics, no matter which state they are located in. A veteran living in a state with a fully legal, well-established medical cannabis program can walk into a private doctor's office in that same state and get a legal recommendation — and cannot get the same thing from a VA provider down the street, because that VA provider is bound by federal, not state, law.
What VA Doctors Can and Can't Do
Under long-standing VA policy (VHA Directive 1315), VA clinicians cannot recommend, prescribe, or fill out state medical marijuana program paperwork for any product containing THC, CBD, or other cannabinoids. The VA also will not pay for medical marijuana obtained through a state program or any other source, and it is not covered under VA health benefits.
What VA clinicians can do is discuss cannabis use openly with veterans and document it in their medical record. The VA has been explicit that veterans will not be denied care or benefits because they use cannabis, including through a state-legal program, and clinicians are expected to factor a veteran's cannabis use into their broader treatment plan rather than penalize them for it.
Does Using Cannabis Put VA Benefits at Risk?
No. Participation in a state medical or recreational cannabis program does not affect a veteran's eligibility for VA healthcare, disability compensation, or other benefits. This is a common point of confusion and anxiety among veterans, but VA policy separates "the VA can't prescribe it" from "the VA will punish you for using it" — the first is true, the second is not.
A Shift in December 2025
On December 18, 2025, President Trump signed an executive order directing federal agencies to reduce research barriers around medical marijuana and CBD, moving to reschedule cannabis from Schedule I to Schedule III under the Controlled Substances Act. The order was framed partly around veterans, citing the benefits some veterans with chronic pain have reported from using cannabis as an alternative to opioid painkillers. The change is intended to make it easier for the VA itself to conduct research into cannabis for pain management, mental health conditions, and other symptoms common among veterans.
What the order does not do, at least immediately, is change VA's prescribing policy. Rescheduling to Schedule III would ease some research and manufacturing restrictions, but it does not by itself make cannabis products FDA-approved or automatically permit VA doctors to prescribe them the way they would any other Schedule III drug. Cannabis products sold at state dispensaries are not FDA-approved medications regardless of scheduling, so the practical prescribing gap for VA patients is expected to persist even as the federal research environment opens up.
The Gap Veterans Are Left With
In the meantime, veterans who want to use cannabis for PTSD symptoms, chronic pain, or other conditions and who live in a legal state are left managing two separate, disconnected systems: a state medical or recreational program they have to access entirely outside the VA, paid for out of pocket, alongside VA care for everything else. It is a direct consequence of cannabis's federal legal status colliding with state-level legalization — the same tension that shows up at national parks, federal buildings, and interstate travel throughout the country, anywhere federal jurisdiction overrides an otherwise fully legal state cannabis market.
