Short answer
A cannabis disposable vape delivers about 100 to 300 hits per gram of oil. Most 0.5 g devices land near 100 to 150 hits. Most 1 g devices land near 200 to 300 hits. No printed puff count is exact, because each user pulls a different volume of oil per draw.

Puff counts by fill size
- 0.3 g: about 60 to 90 hits
- 0.5 g: about 100 to 150 hits
- 1 g: about 200 to 300 hits
- 2 g: about 400 to 600 hits
These ranges assume a 2 to 3 second draw. A 5 second draw moves close to twice the oil of a 2 second draw, so the count drops.

What changes the number
- Draw length. A longer pull moves more oil to the coil.
- Device wattage. Higher heat vaporizes more oil each second.
- Oil viscosity. Thin oil with high terpene content flows faster.
- Clogs and leaks. Oil lost in a clog never reaches the user.
- Coil design and airflow size.
Milligrams of THC per hit
A 1 g cartridge at 85% THC holds about 850 mg of THC. Spread over 250 hits, that works out to about 3.4 mg per hit. By arithmetic, a 10 mg edible serving equals about three hits of that device. That comparison is arithmetic alone. Inhaled THC reaches the bloodstream in minutes. An edible takes 30 to 120 minutes to peak. New users should take one short draw and wait 10 to 15 minutes before a second.
Why labels skip puff counts
State regulators require net weight and tested THC potency on the package. Puff count is not a regulated figure because it depends on user behavior. A package that claims 300 puffs is a marketing estimate, not a measurement.

How to track what is left
Most disposables have a viewing window. Oil level is a better gauge than a mental puff count. Devices often taste burnt near the last 5% to 10% of the fill. Stop at that point. The CDC tied vitamin E acetate to the 2019 EVALI lung injuries, so buy from licensed shops with test labels.
