Legal Medical Marijuana States and DC

For information on recreational marijuana, please visit our Legal Recreational Marijuana States resource.
Showing 1 to 36 of 36 entries
Why are some states not on this list? Our list includes states that have legalized use of the marijuana plant for medical purposes. States that limit use to the nonpsychoactive marijuana extract called cannabidiol (CBD) are not included on this list, although we do keep track of those legal CBD states in our resource States with Laws Specifically about Legal Cannabidiol (CBD). Also not included are states whose legalization laws require physicians to “prescribe” marijuana (an illegal act under federal law) vs. “recommend” marijuana (considered protected free speech between doctor and patient), as well as states that have passed “affirmative defense” laws in which arrested marijuana users are allowed to mention medical use in their defense.From the 1970s to the 1990s, several states passed symbolic laws that liberalized their medical marijuana policies to some degree. For example, some states wrote laws that legalized medical marijuana with a physician’s prescription, however, those laws are considered symbolic laws because federal law prohibits physicians from “prescribing” marijuana, a schedule I drug. Examples include: Virginia (Mar. 27, 1979) and Louisiana (July 23, 1991). Some states wrote laws creating research programs to investigate medical use of marijuana; others allowed for “medical necessity” as a defense in state court. None of these laws made marijuana available to patients with a doctor’s recommendation, and are thus considered symbolic.All states require proof of residency to apply to be qualifying patients, although the length of time considered to be a resident varies by state. Some states require registration and registry fees.
