A cannabis concentrate dosage chart maps THC milligrams to tolerance level. Concentrates test at 60% to 90% THC by weight. One gram of 80% THC wax holds 800 mg of THC. No standard serving size exists for dabs or vape oil. A new user should start at 1 to 2.5 mg of THC and wait 15 minutes before adding more.
Concentrate potency versus flower
Dried flower tests at 15% to 25% THC in most state-licensed markets. Concentrates strip plant material and raise potency. One gram of 80% concentrate equals about 8 half-gram joints of 20% flower. That math matters when a label lists grams instead of milligrams.
Concentrate dosage chart by tolerance
The ranges below come from harm reduction guidance and state health material. They are estimates, not clinical standards. Response varies with body weight, method of use, and prior use. Research on concentrate dosing in humans is limited.
Cannabis Concentrate Dosing Guide: How Much THC to Take
- No prior THC use: 1 to 2.5 mg
- Use a few times a year: 2.5 to 5 mg
- Monthly use: 5 to 10 mg
- Weekly use: 10 to 25 mg
- Daily use: 25 to 50 mg
- Long-term high tolerance: 50 to 100 mg
How much THC sits in one dab
A dab the size of a grain of rice weighs about 25 mg. At 80% THC that dab carries 20 mg of THC. A pea-size dab weighs 50 to 100 mg and carries 40 to 80 mg of THC. A user with low tolerance can reach impairment from less than a rice-grain dab.

Onset and duration by method
- Inhaled (dab, vape pen): onset 30 seconds to 5 minutes. Peak at 15 to 30 minutes. Effects fade in 1 to 3 hours.
- Oral (tincture, capsule, edible): onset 30 to 90 minutes. Peak at 2 to 4 hours. Effects fade in 4 to 8 hours.
Reading a concentrate label
Look for total THC, THC per serving, THC per package, and CBD content. Some states cap a single serving at 10 mg THC for infused products. Concentrate jars sold by the gram may carry no serving markings. Divide total THC by the number of doses you plan to take. Ask for the certificate of analysis if potency numbers are missing.
Purchase limits in two states
- Colorado: 8 grams of concentrate per retail transaction.
- Washington: 7 grams of concentrate per retail transaction.
Risk notes
- High-THC products can trigger anxiety, fast heart rate, and paranoia.
- Daily use of high-potency concentrate is linked to cannabis use disorder and, in a small number of users, psychosis.
- Do not drive after use.
- Store concentrate in a locked container away from children and pets.
- Health agencies advise against cannabis use during pregnancy and breastfeeding.
