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.
How many mg of THC should I take?
Start with 2.5 mg to 5 mg of THC. For an edible, wait 2 hours before a second dose. For inhalation, take one or two puffs and wait 15 minutes. A 10 mg dose is one serving in US states with legal retail cannabis. That number is a package limit. It is not a first dose.

What 10 mg means on a label
Colorado and Washington cap a recreational edible serving at 10 mg of THC. A package holds up to 100 mg. A label that reads 100 mg total is not one dose. Find THC per serving on the label. A bar with 10 pieces and 100 mg total holds 10 mg per piece. Half a piece is 5 mg.
Edibles
Edible THC goes through the liver. Effects start in 30 to 90 minutes. They peak near 2 to 3 hours. A second dose at 30 minutes adds THC. It does not add effect at 30 minutes. Wait 2 hours. New user: 2.5 mg. User with tolerance: 5 mg to 10 mg. Do not start at 50 mg.
Inhalation
Inhaled THC reaches blood in seconds. Effects peak in 10 to 30 minutes and fade in 1 to 3 hours. One puff from a joint or vape delivers 1 mg to 3 mg of THC. Start with one puff. Wait 15 minutes. Two puffs are a common second step.
Tolerance, weight, and product
Body weight is a weak predictor of THC dose. Tolerance and product potency matter more. A daily user may need 20 mg to 50 mg for an effect that 5 mg gives a new user. A person with no use in 30 days has low tolerance. A concentrate at 70% to 90% THC delivers a dose that is hard to measure in milligrams. Treat one puff as the unit.
Signs of too much THC
Signs: fast heart rate, anxiety, nausea, dry mouth, and a sense of losing control. Edible effects peak in 1 to 3 hours. They pass. Do not take more cannabis to counter them. Sit down, drink water, and wait. Get medical help for chest pain, severe vomiting, or thoughts of self-harm.
Groups that should take 0 mg
People under 21 in US legal states. People who are pregnant or breastfeeding. People with a history of psychosis. People who plan to drive. Cannabis impairs driving for 4 hours or more after inhalation and longer after edibles. Check state law.
