How much THC should a first-time edible user take?
Start at 2.5 mg to 5 mg THC. Colorado sets one edible serving at 10 mg THC. A first session below that serving limit leaves room for error. Do not redose for at least two hours.
Onset and peak timing
Edible THC passes through the liver before it reaches blood. Onset runs 30 minutes to 2 hours. Peak blood levels land near 2 to 4 hours. Effects can last 4 to 8 hours. A single dose can stay active longer in some people. Set a timer. Do not judge the dose at 45 minutes.

What changes the dose
- Body weight and body fat. THC stores in fat tissue.
- Tolerance. Daily users need more THC than new users.
- Food in the stomach. A heavy meal can delay onset.
- Product type. Drinks act faster than gummies in some reports. Hard data is thin.
- Liver enzymes and genetics. Some people convert THC to 11-hydroxy-THC at higher rates.
Steps for a first session
- Read the label. Find mg THC per piece, not per package. A 100 mg package with 10 pieces holds 10 mg per piece.
- Cut the piece. A 10 mg gummy cut in four gives 2.5 mg.
- Eat a light snack. Note the time.
- Wait 2 hours before a second dose.
- Take the second dose at half the first dose, not double.
- Keep water nearby. Do not drive.
Signs of too much THC
Common signs: dry mouth, fast heart rate, anxiety, nausea, and a sense of time slowing. Severe signs: vomiting, chest pain, panic, and confusion. These effects do not cause death from THC alone, but they can cause falls, panic, and ER visits. Lie down. Drink water. Call 911 for chest pain, fainting, or trouble breathing. Call Poison Control for dosing questions.
Storage and packaging
Keep edibles in the original child-resistant package. Store away from food. Children and pets eat edibles by accident. Label the container with the date and mg per piece. Keep a written log of time and dose for the first three sessions.

Why convenience formats matter
Gummies, mints, drinks, and pre-dosed squares remove preparation steps. That convenience raises one risk: repeat dosing. A mint at 5 mg looks like a breath mint. The package label is the control. Check mg per unit each time. A 10 mg serving is a limit, not a target for a new user.
