How Long Do Cannabis Edibles Last: Gummies Edition
Discover the duration of cannabis edibles' effects with a focus on gummies.
Short answer
A standard edible dose of 5 to 10 mg THC produces effects that last 4 to 8 hours. Doses of 20 mg and above can run 12 hours or longer. Onset takes 30 to 120 minutes because THC travels through the stomach and liver before reaching the bloodstream. Unopened edibles hold potency for 6 to 12 months in cool, dark storage. Some gummies and tinctures stay stable for 24 months.

How long an edible high lasts
Edibles act slower than inhaled cannabis. The liver converts THC into 11-hydroxy-THC, a metabolite with stronger psychoactive effects. That conversion step adds time to onset and extends the total duration.
- Onset: 30 to 120 minutes. A heavy meal before dosing can push this to 2 hours.
- Peak effects: 2 to 4 hours after eating.
- Total duration at 5 to 10 mg: 4 to 8 hours.
- Total duration at 20 to 50 mg: 8 to 12 hours, sometimes longer.
New users should start at 2.5 to 5 mg. Wait 2 hours before taking a second dose.
Shelf life of edibles
THC degrades into cannabinol (CBN) over time. CBN is less psychoactive and more sedating. Potency can drop 10 to 20 percent after 12 months in warm or humid conditions.
how long do weed edibles last vs smoking
- Gummies: 12 to 24 months. Sugar and gelatin slow degradation.
- Chocolate: 6 to 12 months. Cocoa butter turns stale and blooms.
- Baked goods: 3 to 7 days at room temperature, up to 3 months frozen.
- Tinctures and oils: 12 to 24 months in amber glass.
Label dates vary by state. Colorado requires expiration dates. California prints a "best by" date. No federal standard exists for edible shelf life.
Storage rules
- Keep edibles at 65 to 75 F. Heat speeds THC breakdown.
- Block light. UV degrades cannabinoids in weeks.
- Seal in airtight containers. Air exposure oxidizes THC.
- Refrigerate chocolate and baked goods. Freeze baked goods for long storage.
- Store away from children and pets. Packaging rules in most states require child-resistant containers.
Factors that change duration
- Dose size.
- Tolerance from regular use.
- Body weight and body fat percentage.
- Liver enzyme activity, which varies by person and by genetics.
- Food in the stomach at the time of dosing.
- Other drugs or alcohol taken at the same time.
Signs an edible has gone bad
Mold on baked goods is visible. Chocolate with a white or gray film has bloomed, which is safe but stale. Gummies that harden, melt, or stick together have lost texture. A weak or absent effect points to potency loss. No home test measures THC content in food.
