Short answer
Cannabis baked goods take 30 to 120 minutes to produce noticeable effects. Most people feel the first shift between 45 and 90 minutes after eating. Peak effects arrive 2 to 4 hours after the dose, and the full effect can last 4 to 12 hours.

That timeline runs slower and longer than smoking or vaping, where effects start in minutes and fade within 1 to 3 hours.
Why baked goods work slower
Inhaled THC moves from the lungs into the bloodstream and reaches the brain within seconds. A cookie or brownie sends THC through the stomach and liver first. The liver converts THC into 11-hydroxy-THC, a metabolite that crosses into the brain and produces a stronger, longer high. That extra step is the reason edibles hit later and land harder.
What changes your timeline
- Dose. A 5 mg serving may register as light body relaxation at 60 minutes. A 50 mg serving hits the same person with more intensity, and the stronger effect can feel like it started sooner.
- Food in the stomach. A full meal slows stomach emptying and can push onset past 2 hours. An empty stomach moves the dose along faster.
- Type of baked good. A dense fudge brownie digests slower than a light sugar cookie. Fat content matters, since THC binds to fat.
- Body weight, liver enzymes, and tolerance. These factors shift onset by 30 minutes or more between two people eating the same product.
- Product accuracy. Homemade butter and oil carry uneven THC. Labeled dispensary products are dosed closer to spec.
Timeline at a glance
- 10 to 30 minutes: little or nothing. Do not take more.
- 30 to 120 minutes: first effects, often warmth, relaxation, or a shift in mood.
- 2 to 4 hours: peak effect.
- 4 to 12 hours: comedown, with residual effects.
What to do while you wait
- Note the time you ate the dose.
- Wait at least 2 hours before taking any more.
- Drink water and eat a light snack if your stomach feels empty.
- Stay in a comfortable setting with people you trust.
- Skip alcohol and other depressants, which stack with THC.
- Set a reminder for the 4 hour mark to check how you feel.
Signs you took too much
Dry mouth, fast heartbeat, nausea, dizziness, and anxiety are common with a high dose. These effects pass, but they can feel intense. Sit down, breathe, and sip water. Seek medical help if you have chest pain, trouble breathing, or severe vomiting.

Buying baked goods at a dispensary
Read the label for total THC per package and THC per serving. A package that lists 100 mg total with 10 servings holds 10 mg per piece. Cut the piece in half if you want 5 mg. Store baked goods away from children and pets, since the delayed onset means a child can eat more before anyone notices.
