Cannabis gummies dosage: standard serving
In states with legal adult-use cannabis, a standard serving is 10 mg THC. Colorado, Washington, and California cap each serving at 10 mg. Most packages hold 100 mg THC total. That equals 10 gummies at 10 mg each, or 20 gummies at 5 mg each.
Medical markets sell higher doses. A single piece can contain 50 mg or 100 mg THC. Check the label for two numbers: mg per piece and mg per package.
Start low
A first dose is 2.5 mg THC. Some people start at 1 mg. Wait 2 hours before taking more. Do not redose after 30 minutes. The effect is not visible yet at that point.
Onset, peak, and duration
Gummies pass through the stomach and liver. Onset is 30 to 120 minutes. Peak effects arrive at 2 to 4 hours. Effects last 4 to 8 hours. Some users report 12 hours. Inhaled cannabis acts in 5 to 10 minutes.

THC is metabolized by liver enzymes, including CYP2C9 and CYP3A4. The liver converts THC into 11-hydroxy-THC. This metabolite is more potent than THC and crosses the blood-brain barrier.
What changes your dose
- Body weight and body fat.
- Tolerance. Daily users need more THC for the same effect.
- Food. A fatty meal can raise absorption.
- Alcohol and other drugs. Alcohol raises blood THC levels.
- CBD. CBD can slow THC metabolism by blocking CYP enzymes.
- Liver function and genetics.
Steps for a first dose
- Read the package label. Find mg THC per gummy.
- Cut the gummy into quarters if it is 10 mg.
- Take 2.5 mg. Note the time.
- Wait 2 hours. Do not take more during this window.
- Record effects at 2, 4, and 6 hours.
- Next session, add 2.5 mg if the first dose did nothing.
- Do not mix with alcohol on a first dose.
Signs of too much THC
Overtaking a gummy causes anxiety, paranoia, a fast heart rate, nausea, vomiting, and unsteady walking. These effects peak at 2 to 4 hours. No fatal overdose from cannabis alone has been reported. A high dose can cause a panic attack that feels like a heart attack. Call Poison Control at 1-800-222-1222 for advice.
Tolerance and breaks
Daily use builds tolerance in 1 to 2 weeks. A break of 2 to 4 weeks lowers tolerance. During a break, sleep and mood can change for 3 to 7 days.
Storage
Keep gummies in the child-resistant package. Store them locked away from children and pets. Children who eat THC gummies face a higher risk of hospital visits. Edible packages look like candy.
