Most people should start with 1 to 2.5 mg of THC, wait a full two hours, and only then decide whether to take more. Five milligrams is the standard single serving in legal US markets, and 10 mg is the legal per-serving cap in states like Colorado and Washington. Anything past 10 mg is for people who already know exactly how edibles treat them.
Why edibles hit harder than a vape or a joint
Inhaled THC goes to your lungs, into your blood, and up to your brain in minutes. Eaten THC takes a detour through your liver, which converts it into 11-hydroxy-THC. That metabolite crosses the blood-brain barrier more readily and sticks around longer, so the same milligram count feels stronger and lasts longer when you eat it.
how long do cannabis edibles take to kick in
The timeline matters as much as the number:

- Onset: 30 minutes to 2 hours, sometimes longer on a full stomach.
- Peak: roughly 2 to 4 hours after you eat it.
- Duration: 4 to 8 hours, with a foggy tail that can run longer.
That delay is why people get into trouble. They feel nothing at 45 minutes, eat another piece, and then both doses land at once.
THC edibles dosage chart
These ranges assume a standard product with THC as the main active cannabinoid. Treat them as starting points, not prescriptions.
- 1 to 2.5 mg: First-timers, anyone who reacts strongly to small amounts, and older adults on multiple medications.
- 2.5 to 5 mg: Low tolerance or occasional users. 5 mg is the classic single serving and a good ceiling for a first real experience.
- 5 to 10 mg: Regular users with some edible history. This is where most experienced casual consumers land.
- 10 to 25 mg: Daily consumers or people using cannabis for symptom relief. Expect meaningful impairment.
- 25 to 50 mg and up: High-tolerance medical patients and heavy daily users only. Not a recreational starting point, ever.
CBD edibles follow a different scale
CBD does not intoxicate, so the milligram numbers run much higher. A lot of people find 10 to 25 mg useful for general calm, 25 to 50 mg for sleep or anxiety before bed, and clinical research often uses 100 mg or more per day for specific conditions. CBD can also nudge how your liver breaks down THC, so a balanced 1:1 product is not the same as a pure THC gummy with the same total milligrams.
What moves your number up or down
- Tolerance. The single biggest factor. Daily use blunts the response.
- Body composition. THC is fat-soluble and stores in fat tissue, which can stretch out the effects.
- Liver enzymes. Genetics and medications change how fast you convert THC. Some people are slow metabolizers and get wrecked by 2.5 mg.
- Food. A fatty meal before dosing can increase absorption and delay the peak.
- Alcohol and sedatives. Bad combination. It amplifies impairment and increases the odds of a rough night.
- Labeling. Check milligrams per piece, not per package. A 100 mg chocolate bar cut into ten squares is a 10 mg dose per square.
Rules I would follow every time
- Read the label and calculate the dose yourself instead of trusting the packaging graphic.
- Start at 1 to 2.5 mg if you have never eaten cannabis.
- Set a timer and wait two hours before taking more. No exceptions.
- Skip the drinks, or keep it to one and expect a stronger ride.
- Keep a high-CBD product around. It will not cancel a THC high, but many people find it takes the edge off.
- Do not drive. Edibles impair reaction time for hours after the buzz fades.
- Store everything in a locked container, away from kids and pets.
If you take too much
It happens, and it is rarely dangerous in a physical sense. Expect a racing heart, nausea, anxiety, and possibly paranoia for a few hours. Drink water, lie down somewhere calm, put on something low-key, and remind yourself the peak passes. Do not take more THC to "fix" it, and do not add alcohol. If chest pain, severe vomiting, or confusion shows up, get medical help and tell them what you took and how much.
