What Does a Medical Cannabis Doctor Prescribe? Guide

What does a medical cannabis doctor prescribe?

In most US states, a medical cannabis doctor does not write a prescription for cannabis. The doctor issues a certification or written recommendation that allows a patient to buy cannabis from a licensed dispensary. Only FDA-approved cannabinoid medicines such as dronabinol, nabilone, and cannabidiol oral solution are true prescriptions.

Why the word prescribe is not accurate

Cannabis remains a Schedule I controlled substance under federal law, so a standard prescription cannot be filled at a pharmacy. State medical cannabis programs use the terms certification, recommendation, or authorization instead. A recommendation carries legal weight inside the state program but is not the same as a prescription.

What can actually be prescribed

• Dronabinol (Marinol, Syndros), a synthetic THC capsule or liquid for nausea and appetite loss.
• Nabilone (Cesamet), a synthetic cannabinoid for chemotherapy-related nausea.
• Cannabidiol oral solution (Epidiolex) for certain severe seizure disorders.

These three drugs go through a pharmacy with a standard prescription and are available in every state.

What a medical cannabis doctor does provide

A licensed physician, nurse practitioner, or physician assistant evaluates your condition, reviews your history, and decides whether you qualify under state rules. The certification that follows lists your name, the issuing provider, the qualifying condition, an issue date, and an expiration date. Many states also print a patient ID number and a possession limit.

Does the certification name a specific product?

Sometimes. Some providers add a suggested cannabinoid ratio, a THC range, or a preferred route of administration. Others leave product choice to the patient and the dispensary staff.

What clinical guidance usually looks like

• Route: inhalation, tincture, capsule, edible, topical, or sublingual oil.
• Ratio: CBD-dominant, balanced THC to CBD, or THC-dominant.
• Starting dose: often low, such as 1 to 2.5 mg of THC per dose.
• Titration: small increases every few days until symptoms ease.
• Daily limits: a maximum suggested amount of THC per day.

Why dosing advice matters more than the product name

Cannabis affects people differently based on body weight, tolerance, liver enzymes, and how it is consumed. A doctor's role is to set a starting point and a schedule for adjusting it. Inhaled effects appear within minutes, while edibles can take one to two hours and last much longer.

What medical cannabis doctors do not do

They do not dispense cannabis, sell flower, or hand out samples. They also cannot guarantee a specific strain or brand, since dispensary inventories change. A provider who promises a fixed product or guaranteed approval is a warning sign.

Questions to ask at your appointment

1. Which qualifying condition is listed on my certification?
2. What starting dose and ratio do you suggest for my symptoms?
3. How long should I wait before increasing the dose?
4. Which side effects or drug interactions should I watch for?
5. When does the certification expire and how do I renew it?

How long does a certification last?

Most states issue certifications valid for 6 to 12 months, and renewal requires a new appointment. Some states allow telehealth visits for the evaluation.
