How long does a half gram THC cart last?
Buy by dose, not puff count. A half gram cart holds about 350 to 450 mg THC at 70 to 90 percent potency, so it can last about 1 to 4 weeks for casual use and longer for microdosing. For predictable duration, choose a lab-tested cart with clear potency and batch info, then use a low-voltage battery and track your daily milligrams.
How Long Does a Cannabis Cart Last in Storage?
Label math is simple: usable THC divided by daily dose. A 0.5 g cart at 80 percent THC contains about 400 mg THC. At 5 mg per day, that is about 80 days by label math. Real use often runs shorter because draws vary, some oil is lost to heat or clogging, and tolerance can rise.
How Many Days Does a Cart Last for a Daily User?
What determines cart life
- Potency: higher THC per gram means more milligrams in the same cart, so dose changes the count.
- Your dose: a 2 to 5 mg draw pattern stretches a cart far longer than 20 to 40 mg per day.
- Device and voltage: high heat can burn oil faster and create a harsher hit.
- Draw size: long pulls use more oil than short pulls.
- Oil type: thick oils can clog and leak if stored or heated poorly.
- Sharing: a cart shared with friends lasts less than one used alone.
What to look for when buying
Look for a regulated product with total THC and batch testing on the package. Check for pesticide, heavy metal, residual solvent, and microbial tests. A batch date helps you avoid old oil. Hardware should list a voltage range, and the cart should have a mouthpiece that seals well. Clear potency lets you compare a 0.5 g cart to a 1 g cart without guessing.
For a first cart, a moderate potency product and a battery with low settings are easier to control than a high-potency cart and a fixed high-voltage pen.

Parameter bands to use
- Potency: 70 to 85 percent THC is common for distillate; live resin and rosin often sit lower. Use the label, not the strain name.
- Voltage: 2.5 to 3.0 V for flavor and small draws; 3.0 to 3.6 V for thicker oil. Above 3.8 V raises the risk of burnt oil.
- Daily dose: 2 to 5 mg for new users; 5 to 10 mg for moderate use; 10 to 25 mg for high tolerance. Start low.
- Expected life at 400 mg THC: 5 mg per day, 6 to 12 weeks; 10 mg per day, 3 to 6 weeks; 20 mg per day, 2 to 4 weeks; 40 mg per day, 1 to 2 weeks.
These bands assume the label is accurate and the device works well. Leaks, clogs, and high heat can cut the range.
Common pitfalls
- Counting puffs instead of milligrams. Puff size changes with battery, oil, and draw.
- Using the highest voltage to get a bigger cloud. It can waste oil and spoil flavor.
- Buying a cart with no batch or test info. You cannot judge dose or quality.
- Storing a cart in a hot car or on its side. Heat and position can cause leaks.
- Sharing a cart and losing track of dose. Tolerance and intake vary by person.
FAQ
How many puffs does a half gram cart give?
There is no fixed number. A 0.5 g cart may deliver dozens to well over a hundred puffs, but draw size, voltage, and oil loss change the count. Dose in milligrams is a better planning tool.
Does a higher voltage make a cart last longer?
No. Higher heat can use more oil per draw and degrade the oil. Low to medium voltage usually gives better control.
Why did my half gram cart empty fast?
Common causes are large draws, high tolerance, high voltage, sharing, leaks, and clogging. Track daily milligrams to see the real driver.
Can I make a THC cart last longer?
Use short draws at low voltage, store the cart upright, keep it away from heat, and set a daily dose. A lab-tested cart with clear potency also helps you avoid overshooting.
