Medical cannabis eligibility conditions are set by each state, so no single national list applies everywhere. In most programs you need a documented diagnosis of a qualifying condition plus written certification from a physician registered with that state. The conditions that appear most often are chronic pain, cancer, epilepsy and other seizure disorders, multiple sclerosis, glaucoma, PTSD, Crohn's disease and other inflammatory bowel diseases, and severe nausea or persistent muscle spasms.

Why Eligibility Changes From State to State
Cannabis remains illegal under federal law, which leaves medical programs to state legislatures and health agencies. A condition that qualifies in one state may be rejected in a neighboring one. Some states publish a closed list of qualifying conditions. Others let a physician certify any condition for which they believe cannabis may help. A few have added broad language such as "any debilitating condition" or "any condition for which an opioid could be prescribed."

Programs also revise their lists over time. PTSD, autism spectrum disorder, and opioid use disorder have been added in multiple states in recent years, while some states have tightened conditions after review by a medical board.

The Most Common Qualifying Conditions
These categories cover the bulk of state lists. Exact wording and inclusion vary, so check your own state registry before you book an appointment.
Pain and physical symptoms
- Chronic pain, including severe or intractable pain
- Cancer and the side effects of cancer treatment
- Severe or chronic nausea, including chemotherapy-induced nausea
- Wasting syndrome, cachexia, or severe appetite loss
- Persistent muscle spasms, including spasticity from spinal cord injury
- Glaucoma and other conditions with increased intraocular pressure
- Arthritis, neuropathy, and back or joint pain (state dependent)
- Migraine and severe headache disorders (state dependent)
Neurological conditions
- Epilepsy and other seizure disorders
- Multiple sclerosis
- Amyotrophic lateral sclerosis (ALS)
- Parkinson's disease
- Huntington's disease
- Alzheimer's disease (in some states)
- Tourette syndrome
- Damage to the nervous system or spinal cord
Mental and behavioral health
- Post-traumatic stress disorder (PTSD)
- Anxiety disorders (a smaller number of states)
- Opioid use disorder or dependence (in some states)
Other conditions on many lists
- HIV or AIDS
- Crohn's disease, ulcerative colitis, and irritable bowel syndrome (varies)
- Hepatitis C
- Terminal illness or a life-limiting diagnosis
- Autism spectrum disorder (in several states, often with age limits)
- A rare or chronic disease the state has approved by petition
Conditions That Rarely Qualify
Some diagnoses are common but usually fall outside medical cannabis programs. Mild or short-term insomnia, ordinary tension headaches, uncomplicated anxiety, and general stress are rejected in most states unless they come with a qualifying condition. A few states do allow anxiety or insomnia, so the rule is not absolute.
What You Need Besides a Diagnosis
Meeting the condition list is only one requirement. Programs generally also ask for:
- A diagnosis documented in your medical records, often from a recent visit
- An in-person or telehealth appointment with a physician, nurse practitioner, or physician assistant approved by the state
- Proof of residency, such as a driver's license, state ID, or utility bill
- A government ID and, for minors, a parent or guardian as caregiver
- Registration with the state health department and payment of a fee
- Renewal every year or two, sometimes with a new certification
Some states also cap how much you can buy, require a dispensary to log each sale in a tracking system, and limit home cultivation.
How to Check Your Own Eligibility
Start with your state health department's medical cannabis page, because that is the source of truth. Search the qualifying conditions section for your diagnosis, then review the list of certifying providers. Bring your medical records to the appointment, since a certifying physician usually cannot diagnose a brand new condition during a cannabis evaluation. If your condition is not listed, ask whether the state accepts petitions to add conditions. That process often takes months.
Keep in mind that a state program does not make cannabis legal everywhere. Crossing state lines with medical cannabis can create legal problems, and employers, landlords, and federal property rules may still restrict use.
