A standard edible dose in the United States is 10 milligrams of THC. That is the single-serving size written into law in Colorado, California, Washington, and most other legal states, and it is the number a label lists as one serving. It is also not a beginner dose. If you have never taken an edible, the working advice from regulators and clinicians is to start at 2.5 to 5 mg, then wait at least two hours before deciding whether to add anything.
what is a standard edible dose
Where the 10 mg number comes from
The 10 mg serving did not come out of pharmacology labs. It came out of state rulemaking. Colorado's regulators settled on 10 mg per serving and 100 mg per package when recreational sales launched, and other states copied the framework because it was already on packaging templates, testing software, and retail systems. California now enforces the same 10 mg serving and 100 mg package cap. Canada landed on 10 mg per package, which tells you the number is a policy choice more than a biological constant.
Can You Overdose on Edibles? Effects, Risks, and What to Do
That matters when you shop. A 10 mg serving is a legal standard, not a promise that 10 mg will feel the same for you as it does for your neighbor.
Why a starter dose sits below the standard
Edibles are not smoked flower with a different delivery method. When you swallow THC, it passes through your liver and converts into 11-hydroxy-THC, a metabolite that crosses into the brain more readily and hangs around longer. The result is a slower, heavier, longer ride. A hit off a vape peaks in minutes. A 10 mg gummy can take 90 minutes to show up and then keep building for another hour after that.
That delay is where most bad edible stories come from. Someone eats 10 mg, feels nothing at 45 minutes, eats another 10 mg, and then both servings land at once. Two hours is the minimum wait. Three is safer if you ate a big meal first.
How long an edible takes to hit and how long it lasts
- Onset: 30 minutes to 2 hours for standard baked goods and gummies
- Peak: roughly 2 to 4 hours after swallowing
- Total duration: 4 to 8 hours, with a foggy tail that can run longer
- Fast-onset formats: nano-emulsified drinks and some sublingual strips can start in 15 to 30 minutes and clear faster
What actually changes how a dose hits you
- Tolerance. Daily users can need 25 to 50 mg for effects a new user gets from 5 mg.
- Liver enzymes. CYP2C9 and CYP3A4 activity varies a lot between people, so metabolism matters more than body weight.
- Food. A fatty meal before an edible tends to slow absorption and stretch the whole experience.
- Product form. Beverages and nano-emulsions behave differently from a brownie or a chocolate bar.
- CBD ratio. High-CBD products often feel less sharp at the same THC number.
- Alcohol and sedatives. Both amplify the impairment and the disorientation. Skip them.
Reading a label without getting fooled
Check the total THC in the whole package, not just per piece. Then check how many pieces the package claims to contain. A bag marked 100 mg with 10 gummies is 10 mg each if you trust the manufacturer. State testing has tightened label accuracy since the early years, but a piece that is cut unevenly or a drink that separates can still deliver more in one sip than another. Shake beverages. Cut gummies along the scored line if there is one.
Quick reference numbers
- 2.5 mg: cautious first dose for a new user
- 5 mg: light, common starting point for occasional users
- 10 mg: standard single serving in most legal states
- 25 to 50 mg: heavy or medical range, typically with built tolerance
- 100 mg: the legal per-package ceiling for retail edibles in most states
Where convenience fits in
The reason 10 mg became the default is partly that it is easy to sell. One gummy, one drink, one dose, no measuring. Convenience has quietly shaped the whole category: single-serve packaging, pre-scored squares, fast-onset nano formats, and low-dose seltzers that let someone have a 2.5 mg option without doing math. That is genuinely useful for dosing discipline. It also makes it easy to treat an edible like a second beer, which is exactly how people overshoot. The number on the package is a reference point. Your own two-hour wait is the better guide.
