Cannabis edibles typically last 4 to 8 hours from onset to comedown, with the strongest effects at 2 to 4 hours in. Onset takes 30 to 90 minutes because THC is digested and processed by the liver. High-dose edibles can run 10 to 12 hours or more, and a sealed edible product keeps its potency for roughly 6 to 12 months when stored correctly.

How long do edibles take to kick in?
Most people feel an edible 30 to 90 minutes after eating it. A full stomach, especially one heavy in fat, can push onset toward the 2-hour mark. This delay is why the common advice is to wait at least 2 hours before taking more.

How long does an edible high last?
The active window for a standard 5 to 10 mg dose is 4 to 8 hours total. Larger doses stretch the timeline, and some users feel aftereffects into the next morning.

- 8 to 12+ hours: high-dose or low-tolerance users
Why do edibles last longer than smoking?
Inhaled THC reaches the bloodstream in seconds and clears in 1 to 3 hours. Edibles pass through the liver, where THC converts into 11-hydroxy-THC, a metabolite that crosses into the brain more readily. That conversion makes edible effects stronger and longer lasting at the same milligram dose.
What makes an edible last longer?
Several factors stretch or shorten the experience, and they stack on each other.
- Dose: 5 mg fades faster than 50 mg
- Tolerance: daily users often feel less for a shorter time
- Metabolism and body weight: faster metabolizers clear THC sooner
- Food eaten before: a fatty meal slows absorption but can boost total absorption
- Product type: baked goods and chocolate digest differently than gummies or drinks
- Sleep and hydration: both affect how groggy the comedown feels
How long do edibles stay fresh?
Most commercially packaged edibles carry a 6 to 12 month shelf life, while homemade batches are best within 1 to 3 months. Over time THC degrades into CBN, which means the edible gets weaker and may feel more sedating. Texture and taste can turn before potency drops enough to notice.
How should you store cannabis edibles?
Heat, light, and air are the main enemies of potency. An airtight container in a cool, dark, dry place keeps most edibles stable for months.
- Keep gummies and baked goods sealed and away from direct sun
- Refrigerate chocolate and anything with a dairy or cream base
- Freeze long-term stock, then thaw sealed to avoid moisture
- Store away from children and pets, ideally in a locked container
How long do edibles stay in your system?
Effects wear off long before THC leaves the body. A single edible can show up on a urine test for up to 3 days, and heavy daily users may test positive for 30 days or longer. Edibles are not detectable for a shorter time than flower, so timing a test around them is unreliable.
Frequently asked questions
How long does a 10 mg edible last?
A 10 mg edible usually runs 4 to 6 hours for a casual user, with a peak around 2 to 3 hours. People with low tolerance may feel it for 8 hours.
Can an edible last 24 hours?
It is uncommon but possible after a very high dose. Residual grogginess, heavy limbs, and slow thinking can persist into the next day even after the main high fades.
Do edibles last longer if you eat them on an empty stomach?
No. An empty stomach usually makes onset faster, not longer. Food, especially fat, delays the start and can increase how much THC is absorbed overall.
What should you do if an edible is too strong?
Stay calm, hydrate, and rest in a safe place. Effects fade with time, but severe symptoms like chest pain, vomiting, or panic warrant a call to poison control or emergency services.
