How Long Does a Cannabis Cart Last? Puff Counts, Days, and What Changes Them
A 1 gram cannabis cart lasts 7 to 14 days for a moderate daily user and 3 to 6 days for a heavy one. Puff counts, voltage, and storage tips.
How many hits are in a full gram cart?
A full gram cart holds 1,000 mg of cannabis oil and gives most users about 200 to 400 hits. Short 2-second puffs push that number toward 400, while long 5-second pulls drop it closer to 150. The average user lands near 300 hits per gram.
That range is an estimate, not a spec printed on the package. Draw size, battery voltage, oil thickness, and cartridge hardware all shift the number. Two people can drain identical carts at different speeds.

What counts as one hit?
One hit equals one draw from the mouthpiece, from the moment you press the button or start the auto-draw until you stop. A 3-second pull and a 6-second pull both count as one hit in casual talk, but they move very different amounts of oil. That gap is the main reason hit counts vary so much between users.

What decides the hit count?
Four factors move the count more than anything else.
- Draw length. A 2-second pull moves about 3 mg of oil. A 5-second pull moves 8 mg or more.
- Voltage. Low settings (2.4V to 2.8V) vaporize less oil per puff. High settings (3.8V to 4.2V) burn through a gram in a hurry.
- Oil viscosity. Thick live resin flows at a slower rate and stretches further than thin distillate.
- Hardware. Clogged or leaking carts waste oil you paid for and never inhaled.
Hits per cart size
Cart size scales the count in a straight line, with some caveats for the big ones.
- 0.5 gram cart: about 100 to 200 hits.
- 1 gram cart: about 200 to 400 hits.
- 2 gram cart: about 400 to 800 hits on paper, though clogs and heat waste cut into that.
Does the type of oil change the count?
Oil type affects flow, and flow affects how much oil leaves the cart per puff.
- Distillate: thin and runny, so each pull moves more oil. Expect the low end of the range.
- Live resin: thicker with more plant compounds, so draws move less oil. Expect more hits per gram.
- Rosin and full-spectrum oils: thickness varies by producer, so the count lands somewhere between the two.
How long does a full gram cart last?
A 1 gram cart at 300 hits lasts about 60 days for someone who takes 5 puffs a day. Ten puffs a day cuts that to about 30 days. A heavy user at 50 puffs a day finishes the cart in under a week.
Daily habits matter more than the label. A cart stored upright and vaped at low voltage tends to outlast the same cart kept in a hot car.
How much THC is in each hit?
A 1 gram cart labeled at 80% THC holds about 800 mg of THC. Spread across 300 hits, that works out to about 2.5 mg per hit. Long pulls at high voltage push single hits past 5 mg.
The per-hit dose matters for tolerance and for anyone new to vapes. Public health guidance groups 2.5 mg with a low dose and flags 5 mg as a level that can feel intense for a first-timer.
Why two people get different numbers from the same cart
Vaping style is personal, and hardware adds noise.
- One person pulls for 2 seconds, another for 6.
- Preheat modes and auto-draw batteries change output.
- Cold weather thickens oil and slows the flow.
- A partial clog forces a longer pull that dumps extra oil.
How to get more hits from one gram
- Lower the voltage. Start at 2.4V to 2.8V for distillate and 2.8V to 3.2V for live resin.
- Take shorter pulls. Two or three seconds moves enough oil to feel the effect.
- Wait between puffs. Effects show up in a minute or two, so pause before adding another hit.
- Store the cart upright in a cool spot. Heat and sideways storage push oil into the airway.
- Clear small clogs with a short dry pull or a toothpick, then resume.
How do you know a cart is almost empty?
- Flavor turns flat or bitter.
- Vapor gets thin and the hit feels weak.
- Oil sits below the intake holes.
- A dry, burnt taste means the wick is running dry. Stop there.
Frequently asked questions
How many hits are in a 0.5 gram cart?
About 100 to 200 hits. A 0.5 gram cart with long, high-voltage pulls can land near 100.
Do 2 gram carts give double the hits?
On paper, yes. In practice, larger carts tend to run at higher voltage and clog more, so the real gain is smaller than double.
Does voltage change the count that much?
Yes. Dropping from 4.0V to 2.8V can add 50 to 100 hits to a gram cart. Lower heat also preserves flavor.
Is there an exact number of hits per gram?
No. Hit count depends on draw size, and no package prints a figure. Treat 200 to 400 hits as a planning range for a full gram cart.
Can a cart burn oil without producing a hit?
Yes. Leaks, clogs, and high heat waste oil. That oil leaves the cart without giving you vapor, which lowers your real hit count.
