Medical Cannabis Dosage Chart Printable: What to Put on It
The best printable medical cannabis dosage chart is a milligram titration log: THC per dose, route columns, 2.5 mg steps, and time-stamped effect notes.
THC dosage chart basics for medical patients
The short answer: there is no single THC dose that fits every medical patient. Start low, go slow, and treat any chart as a range to discuss with your clinician. A dose that helps one person can cause anxiety, dizziness, or sedation in another. Route, tolerance, product strength, body weight, liver health, other medicines, and the condition being treated all change the response.

In the U.S., medical cannabis rules vary by state. Check your program, the product label, and the batch date. I look for the milligram amount per serving and the THC to CBD ratio, not the package size.
Why a chart cannot be a prescription
THC products are not standardized like most prescription drugs. Flower, vape oil, tincture, capsules, and edibles deliver THC at different speeds and strengths. A product labeled 10 mg THC may not hit the same way as another 10 mg product. Absorption also varies from person to person. Oral THC has to pass through the liver, so the same dose can feel weaker or stronger than expected.

A working chart for common routes
Use these as common starting ranges for adults new to THC or returning after a break. They are not goals. Wait for the full effect before taking more.
what is the right dose of medical cannabis
- Inhaled flower or vape: start with one small inhalation, about 1 to 3 mg THC depending on the product. Wait 10 to 15 minutes. Effects peak in about 15 to 30 minutes and fade in 2 to 4 hours.
- Oral edible or capsule: start with 1 to 2.5 mg THC. Wait at least 2 hours, because onset can take 30 to 120 minutes and peak effects can arrive late. Some patients need 5 mg or more, but that is a later step, not a first dose.
- Tincture under the tongue: start with 1 to 2.5 mg THC. Hold it under the tongue as directed, then wait 30 to 60 minutes. Swallowing the tincture shifts it closer to an edible, with a slower onset.
- Topical: follow the product label. Topical THC products are not meant to produce a high, and they are not a substitute for an oral or inhaled dose chart.
How to adjust a THC dose
Keep a simple log: product name, batch, route, dose in milligrams, time taken, onset, peak, duration, and side effects. Change one thing at a time. If a dose feels too strong, do not take more to balance it. Wait it out in a safe place and get help for severe symptoms.
- Increase by the smallest amount the product allows, not by doubling.
- Do not mix alcohol, sedatives, or sleep medicines with THC unless your clinician approves.
- Avoid driving or operating machinery until you know how the dose affects you.
- Use a measured product, not a homemade edible, when you are learning your range.
- Keep oral products locked away from children and pets.
Who needs extra caution
Older adults, people who have never used THC, and patients with heart disease, liver disease, severe mental health conditions, or a history of substance use should get medical advice before starting. Pregnancy and breastfeeding are reasons to avoid cannabis unless a specialist directs otherwise. THC can interact with blood thinners, sedatives, and some seizure medicines.
Stop and call a clinician for chest pain, fainting, severe confusion, repeated vomiting, or thoughts of self-harm. A dosage chart is a tool for a careful conversation, not a green light to push through bad effects.
The bottom line
For medical patients, the safest starting point is a low THC dose, a known route, and a full wait before redosing. Inhaled THC acts fast and fades fast. Oral THC acts slowly and can last longer. Your best chart is the one you build with your clinician and your own written log.
