Short answer

A medical cannabis clinic is a medical practice that evaluates patients and issues a written certification for cannabis. The clinic does not sell cannabis. A dispensary sells it. In most states you need two things before you can buy: a certification signed by a licensed clinician, and a registration card or approval from the state health department.

What happens at a visit

  1. Intake form. Medical history, current medications, and the condition you want covered.
  2. Condition review against the state list. Common entries: chronic pain, cancer, epilepsy, PTSD, multiple sclerosis, Crohn's disease, glaucoma.
  3. Exam or telehealth consult with a physician, nurse practitioner, or physician assistant who holds a state license.
  4. Certification filed in the state registry. You get a card number or a printed approval by email.

Visits run 10 to 30 minutes. Clinics that use telehealth can finish the same day. Physical exams are required in some states, so check before you book.

how does a medical cannabis clinic work

What a clinic cannot do

Cannabis is a Schedule I drug under the federal Controlled Substances Act. A clinician cannot write a standard prescription that a pharmacy fills. The document is a certification or a recommendation, not a prescription. Clinics also cannot promise approval. If a clinician says the card is guaranteed for a fee, that is a warning sign.

Understanding the Cost of Evaluation at Medical Cannabis Clinics

Clinics do not dispense flower, oil, or edibles. That happens at a licensed dispensary.

Costs and documents

  • Photo ID or state driver license.
  • Proof of state residency, such as a utility bill or lease.
  • Medical records, when the clinic asks for them.
  • Payment. Health insurance does not cover the visit in most states. Cash and debit cards are accepted.

Consultation fees run $75 to $300. State registration fees run $0 to $100. Certifications expire after 6 to 12 months, based on state law. Renewal costs about the same as the first visit.

Clinic and dispensary

The clinic handles the medical review and the state paperwork. The dispensary checks your card, logs the sale, and enforces purchase limits. Limits are set per state and per period. Examples include 2.5 ounces per 14 days in some states and 3 ounces per 30 days in others. A dispensary cannot issue or renew a certification.

Points to check before booking

  • Confirm the clinic is licensed in your state and the clinician holds an active license.
  • Ask if telehealth is allowed for your condition.
  • Ask for the total price, including the state fee.
  • Confirm how long the certification lasts and the renewal date.
  • Keep the receipt. Some states require it at the dispensary counter.

Open questions

Federal rescheduling of cannabis has been under review, and the outcome is not final. Rules on possession, transport across state lines, and employment testing differ by state. Check your state program's current rules before you travel with a product.
