Whether 10 mg is a lot depends on your experience. For someone new to edibles, it’s a lot. Health Canada advises new consumers to start with 2.5 mg of THC or less. For a regular consumer, 10 mg is a common standard serving. It’s also the most THC a single package of legal edible cannabis can contain in Canada.
The timing matters as much as the dose. According to Health Canada, edibles can take 30 minutes to 2 hours to start working, up to 4 hours to reach full effect, and last up to 12 hours. Wait before taking more.
Edible doses at a glance
| THC | Who it usually suits |
|---|---|
| 2.5 mg or less | First-timers, and Health Canada’s suggested starting point |
| 5 mg | Occasional consumers |
| 10 mg | Regular consumers; a standard single serving |
| 20–50 mg | Experienced consumers with a higher tolerance |
| 100 mg | Very high tolerance only; usually meant to be divided |
Tolerance, body weight, an empty or full stomach, and the product itself all change how a dose feels. Treat the table as a starting point, not a promise.
10 mg edible vs a joint
There’s no exact match. A joint holds far more THC than 10 mg, but smoking delivers only part of it, and the effect starts and fades within a few hours.
Eating THC works differently. The liver converts some of it to a compound (11-hydroxy-THC) that many people feel more strongly. So a 10 mg edible can feel as strong as a joint or stronger, and it lasts much longer. Questions like “how many gummies equal a joint” don’t have a reliable answer for that reason.
Is 20 mg a lot?
For a beginner, yes: it’s eight times Health Canada’s suggested starting dose. Work up gradually over separate sessions rather than in one sitting.
Common questions
Is 10 mg of THC a lot for a first time?
Yes. Health Canada suggests 2.5 mg or less for a first time, then waiting to feel the full effect before having more.
How strong is a 20 mg gummy?
Strong for most people who aren’t regular consumers. It’s twice a standard 10 mg serving.
Are edibles stronger than smoking?
They often feel stronger and last much longer, even at a lower THC amount, because of how the body processes THC when it’s eaten.
What if I took too much?
Stay somewhere safe and comfortable, drink water, and wait it out; the effects pass. Don’t drive. If you’re worried, call 911 or your provincial health line.
