Edible Dosing Calculator: How Much THC Should You Take?

Edibles are easy to get wrong: they hit slow, hit hard, and last for hours. Tell this free tool your tolerance and what you're going for, and it'll give you a sensible starting dose in milligrams, plus how long it takes and how long it lasts. Start low, go slow, and have a better night.

The edible dosing chart

Prefer to eyeball it? Here's the same guidance as a reference chart. All numbers are milligrams (mg) of THC, and they're starting points for a single dose, not a target to work up to in one night.

ToleranceMicrodoseRelaxedStrongSleep
First time1–2.5 mg2.5 mg5 mg2.5–5 mg

Reference: standard cannabis edible dosing ranges. A 10 mg serving is the common legal-market "standard dose," with 2.5–5 mg widely treated as a low or beginner dose. Experiential guidance, not medical advice.

How edible dosing actually works

The thing that trips everyone up is timing. When you smoke or vape, you feel it within minutes, so you can feel your way to the right amount. Edibles don't work like that. Eaten THC has to pass through your gut and liver first, where it's converted into a stronger, longer-lasting form. That means a slow onset of 30 to 90 minutes, a peak around one to three hours, and a total ride of roughly four to eight hours.

That delay is the whole trap. People take a gummy, feel nothing after 45 minutes, decide it's a dud, eat another, and then both doses arrive together. The fix is boring and it works: take one dose, set a timer, and do not redose for at least two hours.

A few things shift where you should land: an empty stomach hits faster and harder, your body and metabolism matter, and tolerance is the big one. If you use daily, your numbers are much higher than a beginner's, and if your dose keeps creeping up to feel anything, a tolerance break resets it. Want the full primer on finding your number?

Questions, answered

How many milligrams of THC should a beginner take in an edible?

For a true first-timer, start at 1 to 2.5 mg of THC and do not exceed 5 mg. Edibles are stronger and longer-lasting than smoking, and they come on slowly (30 to 90 minutes), so the safest move is to take a low dose, wait a full two hours, and only then decide whether you want a little more next time.

How long does it take for an edible to kick in?

Usually 30 to 90 minutes, sometimes longer on a full stomach. That slow onset is the single biggest reason people overshoot: they feel nothing at 45 minutes, take more, and then both doses land at once. Take your dose, set a timer, and wait at least two hours before redosing.

How long does an edible high last?

Most edible effects last about 4 to 8 hours, with the peak around 1 to 3 hours in. Higher doses last longer, and the tail end can leave some people groggy the next morning. Plan your evening around it and do not drive.

Why are edibles so much stronger than smoking?

When you eat THC, your liver converts it into a more potent, longer-lasting form. That is why a dose that feels mild when smoked can feel intense as an edible, and why starting low matters so much.

What if I take too much?

First, you are going to be okay. You cannot fatally overdose on cannabis alone. Get somewhere calm, hydrate, breathe slowly, and ride it out, because it passes. Our greening out guide walks through exactly what to do, and the rare cases when to call for help.

Is this edible dosing calculator medical advice?

No. It is general harm-reduction information based on widely accepted dosing ranges, not medical advice, and it is meant for adults 21+. Everyone's body, metabolism, and tolerance are different, so treat the result as a smart starting point rather than a precise prescription. If you take medications or have a health condition, talk to a doctor or pharmacist first.

For adults 21+. This tool offers general, experiential harm-reduction guidance based on common cannabis edible dosing ranges. It is not medical advice and is not a substitute for a doctor or pharmacist. Cannabis affects everyone differently. Never drive or operate machinery after use, and keep all edibles away from children and pets. If a child or pet eats an edible, call Poison Control at 1-800-222-1222.
