Medical Cannabis Dosage Chart Printable
Discover the perfect medical cannabis dosage with our printable chart, tailored for US consumers.
There is no single medical marijuana dosage chart in mg that works across every product, and any chart that claims otherwise is skipping the part that matters. A milligram of THC behaves differently depending on how it enters your body. Inhaled cannabis delivers roughly 10 to 25 percent of the THC into the bloodstream. Swallowed cannabis delivers about 4 to 12 percent, and the liver converts a chunk of it into 11-hydroxy-THC, a metabolite that hits harder and lasts longer. A 10 mg gummy and a 10 mg inhale are not the same dose in real life. Match the number to the route first, then titrate to your own response.
What the mg on a label actually counts
Regulated edibles, oils, capsules and vape cartridges list total THC in milligrams per package or per serving. Flower is different: it is sold as a percentage, not a milligram count.
- 1 gram of flower testing 20 percent THC contains about 200 mg of THC in the raw material.
- That does not mean you absorb 200 mg. Combustion destroys some, and your lungs take up only a fraction.
- A 0.3 g joint rolled from that flower holds roughly 60 mg THC on paper, with an absorbed dose closer to 6 to 15 mg.
- A three second draw from a distillate cart is in the neighborhood of 1 to 3 mg THC.
Starter ranges by route
These are conservative entry points for someone with little or no recent THC exposure. Experienced users will need more, sometimes far more, but starting here costs you one uncomfortable evening instead of a bad night.
Cannabis Edibles Dosage Chart: A Guide for Safe Consumption
- Inhaled flower or vape: 1 to 3 mg THC per puff. Wait 10 to 15 minutes before the next one.
- Sublingual tincture or spray: 1 to 2.5 mg THC. Onset runs 15 to 45 minutes.
- Swallowed oil, capsule or gummy: 1 to 2.5 mg THC. Wait at least 2 hours, and up to 4 if you ate a heavy meal.
- Balanced 1:1 products: judge them by the THC number, not the total cannabinoid count. CBD does not erase the THC titration step.
- Dronabinol (prescription THC): the label starts at 2.5 mg twice daily.
- Epidiolex (prescription CBD): dosed by body weight, 2.5 mg per kg twice daily.
One labeling quirk worth knowing: several states define 10 mg THC as one adult retail serving. That is a packaging rule, not a clinical starting dose. Plenty of people find 10 mg of swallowed THC overwhelming on the first try.
How to titrate instead of guessing
- Pick one product and one route. Do not stack an edible and a vape on the same evening while you are learning your number.
- Start at the low end of the range for that route.
- Wait the full onset window before deciding anything. Oral cannabis keeps climbing for 2 to 4 hours.
- Increase by the smallest step the product allows, and no more often than every 2 to 3 days.
- Log the dose, route, and how you feel at one hour, two hours and four hours. Patterns show up fast.
- Settle at the dose that gives relief without wrecking your ability to work, drive or hold a conversation.
What moves your number up or down
Tolerance is the biggest factor, and it shifts within weeks of daily use. Liver function matters for anything swallowed, because first-pass metabolism decides how much 11-hydroxy-THC you produce. Drug interactions run through the same CYP enzymes: warfarin, clobazam, tacrolimus and ketoconazole are the ones clinicians watch. CBD competes for some of those enzymes too, so a high-CBD product can push THC blood levels higher than the label suggests. Body fat, age and whether you took the dose on an empty stomach all nudge the result as well.
Signs the dose was too high
Racing heart, panic, nausea, heavy limbs and a spinning room are the usual markers. Oral doses peak between 2 and 4 hours, so the worst moment often arrives after you have already decided it was not working. Do not take more. Hydrate, lie down somewhere quiet and dim, and let it run. Get medical help for chest pain, repeated vomiting, or confusion that does not clear.
Red flags in charts you find online
- One number per condition, as if cancer pain and muscle spasticity respond identically.
- No route column. This is the single most common flaw.
- No mention of titration speed or waiting periods.
- Numbers pulled from a single small study and presented as universal.
Use any chart as a rough bracket, not a prescription. If you take other medications, or you are treating something beyond sleep and mild pain, run your target dose past a clinician who knows cannabis.
