Doctors don’t technically prescribe marijuana. Because cannabis remains a Schedule I substance under federal law, no physician can write a traditional prescription for it the way they would for other medications. Instead, doctors issue a “recommendation” or “certification” that you qualify for medical cannabis under your state’s program. That distinction matters legally, but the practical process is straightforward: you see a qualified doctor, get certified, register with your state, and visit a licensed dispensary.
As of early 2024, 47 states, Washington D.C., and three U.S. territories allow cannabis use for medical purposes. The specific steps, qualifying conditions, and costs vary by state, but the general path is the same almost everywhere.
Step 1: Check Your State’s Qualifying Conditions
Every medical cannabis program maintains a list of conditions that make you eligible. Some states are strict, limiting access to a handful of severe diagnoses. Others are broad, giving physicians discretion to certify any condition they believe cannabis could help. Common qualifying conditions across most programs include:
- Chronic pain
- Cancer
- Epilepsy and seizure disorders
- HIV/AIDS
- Multiple sclerosis
- PTSD and certain other mental health conditions
- Parkinson’s disease
- Inflammatory bowel disease
- Neuropathy
- Substance use disorder
New York’s program, for example, lists conditions ranging from autism and Alzheimer’s to rheumatoid arthritis and muscular dystrophy, and notes that the list is not exhaustive. Your state’s health department website will have the definitive list. If your condition isn’t explicitly named, it’s still worth asking a physician, since many states allow doctors to use clinical judgment.
Step 2: See a Certified Physician
Not every doctor can recommend cannabis. States require physicians to hold specific credentials. In Ohio, for instance, only MDs and DOs with a full, unrestricted state license who have completed an approved two-hour continuing education course on medical cannabis can issue certifications. Most states have similar requirements, though the details differ.
You have two main options for finding a qualifying doctor. Your existing physician may already be registered with your state’s program, so it’s worth asking. If not, dedicated cannabis evaluation clinics exist in nearly every state with a medical program. These clinics specialize in certifications and can typically see you quickly.
During the visit, the doctor will review your medical history, discuss your symptoms, and determine whether cannabis is appropriate for your situation. This isn’t a rubber stamp. The physician needs to establish a genuine doctor-patient relationship and conduct a proper evaluation. If they determine you qualify, they’ll issue a written certification or recommendation that you’ll use in your state application.
Telehealth Evaluations
Many states now allow you to complete the entire doctor’s visit over video call. New York, Ohio, New Jersey, Pennsylvania, Massachusetts, and California all permit initial certifications through telehealth, provided the evaluation meets the same standard of care as an in-person visit. A few states are more restrictive: Florida, for example, requires your first evaluation to be in person but allows telehealth for annual renewals.
Telehealth evaluations follow the same process as office visits. You’ll connect with a licensed physician in your state via secure video, discuss your medical history and symptoms, and receive your certification electronically if you qualify. This option has made access significantly easier for people in rural areas or those with mobility issues.
Step 3: Apply for Your State Card
Once you have your physician’s certification, you’ll register with your state’s medical cannabis program. In most states, this means submitting an online application through the health department’s portal. You’ll typically need to provide:
- Your physician’s written certification
- A government-issued photo ID
- Proof of residency (utility bill, lease agreement, or vehicle registration)
- An application fee
- A recent photo (some states take this at a county office)
Some states handle everything online, while others require an in-person county appointment. California’s program, for example, requires you to visit your county health department in person, where staff verify your documents and take your photo. The county then has up to 30 days to verify your application and five additional days to issue your card, meaning the process can take up to 35 days from submission.
What It Costs
Expect two separate expenses: the physician evaluation and the state registration fee. Doctor visits for cannabis certification typically run between $100 and $250, depending on your state and whether you use a dedicated cannabis clinic or your regular physician. Some insurance plans won’t cover these visits since cannabis remains federally illegal.
State card fees vary widely. California caps its fee at $100, with a 50% reduction for Medicaid (Medi-Cal) recipients and fee waivers for patients in the County Medical Services Program. Orange County, California charges $84. Many states fall in the $50 to $200 range for the card itself. Budget roughly $150 to $400 total for your first year, combining the doctor’s visit and state fees.
Renewals and Expiration
Medical cannabis cards are not permanent. Most states issue them for one year, after which you’ll need both a new physician certification and a renewed state registration. Connecticut’s program is typical: your registration is valid for up to one year from the date of your doctor’s certification, and you can begin the renewal process 30 days before it expires.
Renewal visits are generally shorter and less expensive than the initial evaluation. Your doctor will confirm you’re still under their care, verify that cannabis continues to be appropriate for your condition, and update any changed information. Many states that require an in-person first visit allow renewals via telehealth.
Minors and Caregivers
Patients under 18 can access medical cannabis in many states, but a parent or legal guardian must be involved. In Virginia, for example, a parent or legal guardian must be listed on the written certification from the physician. If a second parent needs dispensary access, the doctor can add them as a registered agent. The minor does not visit the dispensary themselves.
Caregiver designations also exist for adults who are unable to visit dispensaries on their own due to disability or other limitations. The caregiver goes through a separate registration process, often including a background check, and is then authorized to purchase and transport cannabis products on the patient’s behalf.
Using Your Card in Other States
A growing number of states offer some form of reciprocity for out-of-state medical cannabis patients, though the rules vary dramatically. Maine, Michigan, Nevada, New Mexico, Puerto Rico, and Washington D.C. all offer full dispensary access to anyone with a valid out-of-state medical card.
Other states are more limited. Arkansas requires visiting patients to obtain a temporary card valid for 90 days. Hawaii issues visitor cards that expire after 21 days, with a maximum of two per year, and only for patients with specific conditions. Georgia allows out-of-state patients to possess low-THC oil but not purchase it within the state. Iowa similarly permits possession of a limited amount but prohibits purchases.
If you travel frequently, check the specific rules for each state you’ll visit. Carrying cannabis across state lines remains a federal offense regardless of your medical card status, so the practical approach is to purchase in the state where you’ll be using it.
