The Short Answer: Start Low, Go Slow
For your first edible, take 1 to 2.5 mg of THC. Wait at least 2 hours before deciding whether to take more. In many cases, you should not take more that day. This is the core of edible dosing for beginners.

Why Edible Dosing Is Different
When you eat cannabis, your liver converts THC into 11-hydroxy-THC. This metabolite can cross the blood-brain barrier and produce stronger effects than inhaled THC. Onset takes 30 to 90 minutes, peak effects hit at 2 to 4 hours, and the total experience can last 4 to 8 hours. Because of this delay, it is easy to take too much before you feel anything.
How to Read Edible Labels at the Store
Look for three numbers on the package:
- Serving size: the amount of THC in one piece or one labeled dose.
- Total THC per package: the full amount in the container.
- Milligrams (mg) per serving: the key number for dosing.
In US states with legal retail cannabis, a standard serving is often 10 mg THC. For beginners, that is too high. Choose products that are scored or molded so you can break them into 1 mg or 2.5 mg pieces.

A Step-by-Step First-Time Dosing Plan
- Choose an edible with 2.5 mg THC or less per serving.
- Buy a package that you can divide into single servings.
- Set aside at least 4 hours with no driving or obligations.
- Eat a light snack before you take the edible.
- Take one serving (1 to 2.5 mg THC).
- Wait 2 full hours. Do not take more during this time.
- Note how you feel. If you feel nothing after 2 hours, you may take another 1 to 2.5 mg. If you feel any effects, stop for the day.
- Plan to stay home until the effects end.
What to Do If You Take Too Much
Overconsumption can cause anxiety, paranoia, nausea, and a rapid heart rate. These effects are unpleasant but seldom dangerous. Stay calm. Drink water. Rest in a quiet place. Do not drive. If you have severe chest pain, trouble breathing, or you feel like you might hurt yourself, seek medical help.
Store Rules and Budtender Tips
When you visit a cannabis store, bring your ID. You must be 21 or older in most US states. You cannot consume cannabis inside the store or in public. Ask the budtender for low-dose edibles and a dosing chart. Many stores keep a binder or printed guide for beginners. If the budtender pushes a 10 mg or 100 mg product for your first time, ask for something smaller.
Safety Reminders
- Do not mix edibles with alcohol.
- Keep edibles locked away from children and pets.
- Do not drive or operate machinery after eating an edible.
- Start with a lower dose than you think you need.
