Short answer: if you are new, start at 2.5 mg. If you use cannabis occasionally, 5 mg. Regular consumers usually sit between 10 and 20 mg. Whatever you take, wait two full hours before deciding whether to take more — redosing early is the single most common mistake.
The Chart
These are starting points rather than prescriptions. Tolerance varies enormously, and so does individual metabolism — two people of the same weight can respond very differently to the same 10 mg.
Why Edibles Hit Differently
Eaten cannabis is processed by the liver, which converts THC into 11-hydroxy-THC. That metabolite crosses into the brain more readily than inhaled THC, which is why 10 mg eaten can feel stronger and last far longer than a comparable amount smoked.
It also means your smoking tolerance is a poor guide. People who smoke heavily still routinely misjudge edibles.
The Two-Hour Rule
Onset is typically 45 to 90 minutes, and on a full stomach it can stretch past two. Peak effects arrive at two to four hours.
The failure mode is predictable: someone takes 5 mg, feels nothing at 45 minutes, takes another 5 mg, and then both doses land together. Wait the full two hours. If you are still unsure at that point, wait longer rather than adding.
What Changes the Dose You Need
- Tolerance — the biggest factor by a distance
- Food — an empty stomach means faster, sharper onset; a fatty meal increases absorption
- Metabolism — varies widely between individuals
- Product type — nano-emulsified and water-soluble products can onset in 15–30 minutes, so the two-hour rule may be shorter; check the packaging
- Other substances — alcohol in particular amplifies effects unpredictably
Practical Advice for a First Time
Take it at home, in the evening, with nothing you need to do for the next six hours. Have someone with you if you can, or at least someone who knows. Eat something first. Have water nearby.
Buy from a licensed dispensary so the milligram figure on the label is accurate — that is the whole basis of careful dosing, and it is the one thing an unlicensed product cannot give you. See finding a licensed dispensary.

Storing Edibles So the Dose Stays Accurate
A melted and re-set gummy no longer has THC evenly distributed, so you cannot trust the per-piece figure any more. Heat is therefore a dosing problem as well as a quality one.
Keep edibles sealed, cool and dark, in original packaging with the label attached. Details in how to store cannabis gummies and edibles and shelf life in do edibles expire.
Frequently Asked Questions
How many mg of edibles should a beginner take?
2.5 mg, which is half a standard 5 mg gummy. Wait two full hours before considering more.
Is 10mg a lot for an edible?
For a beginner, yes — clearly impairing. For a regular consumer it is a moderate dose.
How long do edibles take to kick in?
Usually 45 to 90 minutes, longer after a large meal. Nano-emulsified products can be faster.
How long do edible effects last?
Four to eight hours for most doses, peaking at two to four, with residual effects sometimes lasting twelve.
Can you build tolerance to edibles?
Yes, and fairly quickly with regular use. A tolerance break restores sensitivity.
