How Many mg of Cannabis Gummies Should I Take?

The short answer

Take 2.5 mg of THC or less for a first dose. Take 5 mg if you have used cannabis before and had no bad reaction. Take 10 mg if you use THC several times a week. One dose means one gummy or one piece of a gummy, not the whole bag. Wait 2 hours before you decide the dose did nothing. Edibles peak later than smoked cannabis, and a mild 30-minute feeling can turn heavy at hour three.

Why the starting number is low

Swallowed THC goes through the liver. The liver converts delta-9 THC into 11-hydroxy-THC. That metabolite reaches the brain in higher concentration than inhaled THC. NIDA reports that edible effects are delayed, stronger, and longer lasting than inhaled effects. That is the reason a 5 mg gummy can hit harder than two puffs of a joint.

Serving limits by market

• Colorado: 10 mg THC per serving, 100 mg THC per package for recreational edibles.
• Canada: 10 mg THC per package for legal edible cannabis.
• United States: no federal serving standard. State rules differ. Hemp-derived gummies sold under the 2018 Farm Bill may carry 10 mg or more per piece with no state cap.

Dose ladder

1. 1 to 2.5 mg: first-timers, adults over 60, people on prescription drugs.
2. 5 mg: adults with prior cannabis experience.
3. 10 mg: regular users with tolerance.
4. 20 mg and up: heavy-tolerance users. Risk of nausea, racing heart, panic, and short-term memory problems climbs at this level.

Timeline after swallowing

• 30 to 120 minutes: onset. An empty stomach sits near 30 minutes. A full meal sits near 120.
• 2 to 4 hours: peak blood levels.
• 4 to 12 hours: effects taper. Some users feel residue into the next morning.

What changes your number

• Body weight. A 120 lb person needs less than a 220 lb person. The gap is smaller than most people think.
• Liver enzymes. CYP2C9 and CYP3A4 activity varies by person. Slow metabolizers get more effect from the same gummy.
• Food. Fat in a meal raises THC absorption.
• CBD. A 1:1 THC to CBD gummy feels softer than THC alone.
• Tolerance. Daily users need more. Weekly users need less.
• Medications. Some antifungals and seizure drugs slow liver clearance of THC.

Practical rules

• Buy from a licensed shop with a lab-tested label. Unregulated gummies can test 3 to 10 times the stated dose.
• Cut the gummy. A 10 mg square halves to 5 mg and quarters to 2.5 mg.
• Note the time you ate it. Check the clock before a second piece.
• Keep a sober person nearby for a first dose.

What is unknown

No US federal agency publishes a standard edible dose. The 2.5 mg and 5 mg figures come from state regulators and clinician guidance, not from controlled trials on first-time users. Individual response varies. Track your own numbers and use them instead of a generic chart.
