How much THC should
you actually take?
Every “I took too much” story starts the same way: someone redosed before the first one kicked in. The free Edibles Dosing Calculator gives you mg ranges by tolerance, onset windows by product, and the four-step walk-back if you ever stack one too high.
The mg chart
Find the row that matches you. Start one row lower.
Tolerance fades fast. A 25-mg-a-night veteran who took two weeks off is functionally a 2.5 mg first-timer again.
| Dose | For whom | What it feels like | Watch out |
|---|---|---|---|
| 1 – 2.5 mg | Microdose / first-timer | Mild mood lift, light body relaxation, fully functional. Most adults feel almost nothing the first time at 2.5 mg. | Start here every single time, even if you used to be a regular. Tolerance resets in ~10 days. |
| 2.5 – 5 mg | Standard recreational | Clear euphoria, mild perceptual shift, social. Recreational state legal-market 'serving' is typically 5 mg. | Wait 90 minutes before deciding it's not working. Most over-doses happen in this window. |
| 5 – 10 mg | Experienced consumer | Strong euphoria, body heaviness, time dilation. Couch-leaning territory for many. | Don't drive. Don't make calendar commitments for the next 6 hours. |
| 10 – 20 mg | High-tolerance daily user | Pronounced sedation, deep body high, altered perception. Pleasant for veterans; overwhelming for everyone else. | Not a starting dose. Not a date-night dose. Not a social-dinner dose. |
| 20 – 50 mg+ | Medical / chronic use | Therapeutic territory for pain, chemo nausea, severe insomnia — under guidance. | Almost always paired with a tolerance regimen and a clinician. |

Onset, peak, duration
Different products. Wildly different timelines.
The single biggest predictor of a bad experience is not the dose — it’s the redose. These windows tell you when to wait, and when you’re actually safe to consider more.
Gummies, chocolates, baked goods
- Onset
- 45 – 120 min
- Peak
- 2 – 3 hr
- Duration
- 4 – 8 hr
Liver metabolizes Δ9-THC into 11-hydroxy-THC. Stronger and longer than smoked.
THC beverages, fast-acting nano gummies
- Onset
- 10 – 30 min
- Peak
- 60 – 90 min
- Duration
- 2 – 4 hr
Closer to smoking onset. Easier to titrate but easier to over-stack too.
Tinctures (sublingual, held under tongue)
- Onset
- 15 – 45 min
- Peak
- 60 – 90 min
- Duration
- 3 – 5 hr
If swallowed, behaves like an edible. Hold for 60 seconds for sublingual onset.
Capsules / softgels
- Onset
- 60 – 120 min
- Peak
- 2 – 4 hr
- Duration
- 6 – 10 hr
Longest duration of any form. Common for sleep dosing.
Four mistakes behind almost every “I took too much”
The patterns that turn 5 mg into 25 mg.
Mistake
Redosing inside the onset window
What actually happens
If nothing happens at 45 min, wait. If nothing happens at 90 min, wait. The second dose hits when the first one finally lands — and now you've doubled it.
Mistake
Treating 10 mg as 'one serving'
What actually happens
5 mg is the legal-market serving in most recreational states for a reason. 10 mg is two servings — and a real experience for anyone under daily tolerance.
Mistake
Eating on an empty stomach 'to feel it faster'
What actually happens
Empty stomach speeds onset but also amplifies peak and the comedown crash. A small fatty snack 30 min before evens the curve.
Mistake
Mixing edibles with alcohol
What actually happens
Alcohol slows THC metabolism and amplifies dizziness. The 'spinning room + green-out' combo almost always involves a drink.

If you’re already too high
The five-step walk-back.
Save it before you need it. Send it to a friend who’s going to need it.
- 1
Hydrate — water, not caffeine. Caffeine spikes the racing heart.
- 2
Chew black peppercorns or sniff fresh ground pepper. β-caryophyllene blunts the high (real, ER-doctor-approved trick).
- 3
CBD oil (10 – 20 mg) if you have it. Partially counters THC.
- 4
Lie down in a dim, familiar room. Put on something boring you already know.
- 5
Remind yourself: nobody has ever died from a THC overdose. You will sleep it off in 4 – 8 hours.
Why this matters
Edibles are the fastest-growing category — and the most-mis-dosed.
Body weight barely matters
Unlike alcohol, edible response is driven mostly by tolerance, liver enzyme profile (CYP3A4), and whether you ate. A 200-lb beginner can be wrecked by 5 mg.
Tolerance comes back fast
~10 days off restores ~80% of receptor sensitivity. The break is the cheapest upgrade you can give your weekend.
Lab numbers vary ±20%
Two gummies labeled 10 mg can deliver anywhere from 7 to 13 mg. The chart works because it’s ranges — not exact mg.
