What potency and dose should you expect?
In many US states with legal cannabis sales, one marijuana gummy serving holds 5 mg or 10 mg THC. A package holds 100 mg THC in 10 servings in many states. California sets 10 mg THC per serving and 100 mg THC per package for adult-use edibles. Several states set the same limits. Medical products can hold more. Read the label for THC per serving and THC per package. Start with 2.5 mg to 5 mg THC if you have no tolerance.
Standard serving sizes
- 5 mg THC: common serving in several states.
- 10 mg THC: maximum adult-use serving in California and Colorado.
- 100 mg THC: maximum adult-use package in California and Colorado.
- 2.5 mg THC: common starting dose for a new user.
Labels list total THC, THC per serving, and number of servings. A gummy can hold more than one serving. Check the package math before you eat a whole piece.
Onset and duration
Edibles pass through the liver. The liver converts THC to 11-hydroxy-THC. Effects start 30 to 90 minutes after ingestion. Peak effects arrive at 2 to 4 hours. Effects last 4 to 8 hours. Food and metabolism change the timeline. Do not take a second dose before 2 hours pass.
