How Many mg of THC Should a Beginner Eat? Starter Doses

How many mg of THC should a beginner eat?

Start with 1 mg to 2.5 mg of THC. Wait at least 2 hours before eating more. Do not start at 10 mg. In states with legal retail sales, 10 mg is one serving for an adult with tolerance, and a package holds up to 10 servings. A beginner eats one tenth of a standard serving, not one serving.

Why the first dose is small

Edibles go through the digestive system. The liver converts THC to 11-hydroxy-THC, a metabolite with stronger effects than inhaled THC. Onset takes 30 minutes to 2 hours. Peak blood levels arrive at 2 to 4 hours. Effects last 4 to 8 hours, and 12 hours or more after a large dose. That delay causes the most common error: eating a second dose before the first one takes effect.

Dose ranges

• 1 mg to 2.5 mg: first-time users, no tolerance.
• 2.5 mg to 5 mg: light tolerance or prior cannabis use.
• 5 mg to 10 mg: routine users.
• 10 mg: one standard serving in most US states with retail sales. Not a beginner dose.

These are ranges, not medical advice. Body weight, liver function, other drugs, and food in the stomach change the response. Federal research on edible dosing is limited. No federal agency sets a dose for adult recreational use.

How to Calculate THC per Serving in Homemade Edibles

Timeline after eating

• 0 to 30 minutes: no effect.
• 30 minutes to 2 hours: onset.
• 2 to 4 hours: peak.
• 4 to 8 hours: decline. Large doses run 12 hours or longer.

How to measure a dose

Labels list total THC per package and THC per serving. Divide the total. A 100 mg chocolate bar cut into 20 pieces gives 5 mg per piece. A 10 mg gummy cut in half gives 5 mg. A quarter gives 2.5 mg. Use a sharp knife. Beverages and liquids are harder to split; measure them in a marked container.

Mistakes that lead to a bad first experience

1. Redosing at 30 or 45 minutes.
2. Eating a full 10 mg serving as a first dose.
3. Mixing edibles with alcohol.
4. Driving after eating THC.
5. Treating mg of CBD and mg of THC as the same thing. The two act in different ways.

If you eat too much

Signs of a large dose: fast heart rate, nausea, anxiety, confusion, and a sense of losing control. These effects pass. Sit or lie down, drink water, and have someone stay with you. Do not drive. Call Poison Control at 1-800-222-1222 for chest pain, repeated vomiting, or trouble breathing.
