Edible Dosing Chart for Beginners: How Much THC to Start With

Beginner Edible Dosing: Start With 2.5 mg THC

For most beginners, the starting dose is 2.5 mg of THC. Wait at least 2 hours before taking more. If you feel nothing after 2 hours, add 2.5 mg. Do not double the dose. This 'start low, go slow' rule is the standard in states with legal cannabis, including Colorado.

Medical Risks of Eating Cannabis Edibles

Why Edible THC Feels Stronger

When you smoke or vape, THC reaches your brain in minutes. When you eat an edible, THC passes through your liver and converts to 11-hydroxy-THC, a compound with stronger effects. The result: a slower onset, a higher peak, and a longer duration. A dose that feels mild at 30 minutes can feel intense at 2 hours. This delay is the main reason beginners take too much.

Beginner Edible Dosing Chart

Use this chart as a reference. Doses are in milligrams (mg) of THC.

First time (2.5 mg): Mild relaxation, slight body change. Best for testing tolerance.
Low dose (2.5 to 5 mg): Light euphoria, calm mood. Common for daytime or social use.
Moderate dose (5 to 10 mg): Clear high, stronger body effects. Standard single serving in many states.
High dose (10 to 20 mg): Intense effects. Not for beginners.
Very high dose (20 mg and up): Heavy impairment. Risk of anxiety and nausea for new users.

How to Measure a Dose

Read the package label. Find total THC and servings per package.
Divide total THC by the number of servings. That number is the dose per serving.
If the edible is scored, cut it along the line to make equal pieces.
If it is not scored, use a sharp knife and a scale for gummies or chocolate. Cut into the smallest practical piece.
Eat only one piece. Put the rest away.
Set a timer for 2 hours. Do not eat more during that window.

Timing Rules That Prevent a Bad Experience

Onset: 30 minutes to 2 hours.
Peak: 2 to 4 hours after eating.
Duration: 4 to 8 hours, sometimes longer.
Wait 2 hours before any additional dose.
Drink water. Eat food if your stomach is empty. A full stomach can slow onset.

Common Beginner Mistakes

Taking a second dose after 30 minutes because 'nothing happened.'
Assuming a 10 mg edible is the same as one hit of a vape. It is not.
Mixing edibles with alcohol or other drugs.
Using a homemade edible with unknown THC content.
Ignoring label math. A package with 100 mg THC and 10 pieces holds 10 mg per piece, not 100 mg.
