A 0.5-gram cart usually gives you somewhere around 80 to 160 puffs at a normal three-second draw, and a 1-gram cart roughly 150 to 300 puffs at standard draw length and voltage. In real-world days, that means a 1g cart often lasts two to three weeks for a moderate daily user, around five to twelve days for a heavy user, and over a month for an occasional one.
So the honest answer is: it depends on you. The number printed on the box is the amount of oil, not a promise of how many hits you'll get. Two people can buy the identical 1g cart and one finishes it in five days while the other is still going three weeks later. The good news is that almost every variable is in your control. Here's how the math actually works and how to get more out of every cart.
How many puffs are really in a cart?
The simplest way to think about it: a cart holds a set amount of oil, and every puff uses a small slice of it. At a standard draw, each hit consumes roughly 3 to 5 milligrams of oil. A 0.5g cart holds 500mg, and a 1g cart holds 1,000mg — so you can do the rough division yourself.
At about 4mg a puff, 500mg works out to around 125 hits, and 1,000mg to around 250. That's why you'll often see "200 to 300 puffs" quoted for a 1g cart. It's a reasonable starting point — not a guarantee. Where you actually land depends on the two things below.
Why your own vaping style changes the number
This is the biggest variable, and it's entirely yours to set. John C, one of our budtenders, puts it simply: how long your cart lasts comes down mostly to how you vape and what oil you're using.
"How you vape" really means two habits. The first is draw length. A long, slow pull moves more oil through the coil than a quick one, so longer drags burn through a cart faster. The second is temperature, which on most pens means your battery's voltage or heat setting. Higher heat vaporizes more oil per hit — bigger clouds, but a shorter-lived cart.
The effect is bigger than people expect. Running a battery at a high voltage instead of a low one can cut your total puff count by 30 to 50 percent. Same oil, same cart — you're just using it up faster. If you're trying to make a cart last, a lower setting and shorter pulls are the two easiest levers to pull.

Why the type of oil matters
The second factor is what's actually inside the cart. Oils aren't all the same thickness, and that changes how fast they're used up.
As John C explains it, thinner oils like distillate tend to vaporize faster than thicker, more full-flavored oils like live resin or rosin. The heavier, more viscous concentrates usually need a lower heat to vaporize properly, which is part of why they can stretch a little further per cart when you dial your battery in correctly. One reason live resin carts often last longer in practice is that they're thicker and run best at lower voltage, which slows oil use.

How to make your cart last longer
If you want more days out of every cart, a few small habits add up:
- Take shorter draws. A two- to three-second pull delivers plenty and uses less oil than a long rip.
- Lower your voltage. If your battery has settings, start low. You'll get smoother, more flavorful vapor and noticeably more puffs.
- Match the setting to the oil. Thicker live resin and rosin want lower heat; thin distillate works fine on a low-to-medium setting too. When in doubt, start low and step up.
- Store it cool and upright. Heat thins oil and can cause leaking or clogging. A cool, dark spot keeps the oil where it belongs.
- Don't over-prime. Constant preheating burns oil even when you're not really hitting it.
How do you know when a cart is running low?
A few easy signs tell you you're near the end:
- The oil window looks empty. If your cart has a clear window, a visual check is the fastest tell.
- The taste turns harsh. As the oil drops, the wick dries out and you start tasting a burnt note instead of clean vapor.
- The vapor gets weak. Thin, wispy hits — even at your normal setting — usually mean there's not much left to vaporize.
When you hit that point, dropping to a lower voltage and taking gentle draws helps you finish what's left without the harsh, dry pulls.
FAQ
How long should a 1g cart last if I vape every day? For a moderate daily user taking about 5 to 10 puffs a day, a 1g cart usually lasts one to two weeks. Heavy users can go through one in under a week, while occasional users may stretch it past a month.
Does a cart that stops working mean it's empty? Not always. A little oil can cling to the sides or the wick after the cart stops vaporizing well. A weak draw, a burnt taste, or an empty-looking window usually means it's genuinely done.
Do vape carts expire? Cannabis oil doesn't spoil like food, but it does degrade over time. Stored cool and upright, an unopened cart can keep for a year or more, while an opened one is best enjoyed within several months for the cleanest flavor.
Why does my cart taste burnt near the end? As the oil runs low, the wick can't stay fully saturated, so you taste dry wick instead of vapor. Lowering your voltage and taking shorter draws near the end helps you finish it cleanly.
In states where cannabis is legal, a licensed dispensary budtender can point you toward a cart size and oil type that fit how often you actually vape — which is the real key to how long it'll last.
