Start low, wait two hours
A first dose of 2.5 mg to 5 mg THC suits most new users. A 10 mg gummy is a full adult serving in states with legal limits. Cut the gummy into quarters or halves with a knife. Wait at least 120 minutes before you take more. The liver converts THC into 11-hydroxy-THC, a compound that crosses the blood-brain barrier with more force than inhaled THC. That step takes time. A second gummy at minute 45 stacks on top of the first and raises the chance of a bad reaction.
Serving limits in legal states
Colorado and Washington cap a single serving at 10 mg THC and a package at 100 mg. The package holds 10 servings. California and Nevada use the same 10 mg and 100 mg rule. Labels list milligrams per piece and milligrams per package. Read both numbers. A bag that says 500 mg holds 50 servings at 10 mg each, not one giant dose.
how to determine cannabis gummies dosage
Onset and duration
- First effects: 30 to 120 minutes
- Peak plasma levels: 2 to 4 hours
- Total duration: 4 to 8 hours
- Residual effects: up to 12 hours in some users
Food changes the timeline. A gummy eaten after a meal absorbs slower than one taken on an empty stomach. High-fat meals can raise absorption.
Dose by tolerance
- New user: 1 mg to 2.5 mg
- Occasional user: 2.5 mg to 5 mg
- Regular user: 5 mg to 10 mg
- High tolerance: 10 mg to 25 mg
These ranges are starting points, not targets. Body weight, liver enzymes, and prior cannabis use change the response. Some people feel 2 mg. Others feel nothing below 20 mg. Track your own numbers in a note on your phone.

CBD gummies
CBD gummies sold online in the US often hold no THC or trace amounts under 0.3 percent. Those products act on different receptors and do not produce a high. Doses in studies run from 25 mg to 600 mg per day. Start at 10 mg to 25 mg and adjust over a week.
Redosing rules
- Set a timer for 120 minutes after the first dose.
- If effects are absent at 120 minutes, take half the first dose.
- Do not redose a third time in one day.
- Drink water. Keep a snack nearby.
If the dose is too high
Anxiety, fast heart rate, and nausea are the common signs. No deaths from cannabis alone are on record. Find a calm room, sit down, and drink water. Black pepper and CBD may ease the edge, though evidence is thin. Call 911 if chest pain or trouble breathing appears.
Storage
Keep gummies in the original package. THC degrades with heat, light, and air. A locked drawer at room temperature works. Keep the bag away from children and pets. Child-resistant packaging is required in legal states, and pets that eat a whole package need a vet call.
