Half-Gram Cannabis Cart: How Long It Lasts | Pop's Cannabis

Short answer

A half-gram cannabis cart holds 500 mg of oil. That is the fill weight, not THC weight. A cart at 80% THC holds about 400 mg THC. Common estimates range from 60 to 150 draws for a half-gram cart. There is no standard puff test. A light user who takes 5 draws a day gets 12 to 30 days. A daily user who takes 20 draws a day gets 3 to 7 days. Heavy draws and high heat cut the count.

What changes draw count

• Draw length: a 2 second draw uses less oil than a 5 second draw.
• Device power: higher voltage and wattage vaporize more oil per draw.
• Oil viscosity and fill: thin oil flows faster; thick oil can clog.
• Cart hardware: coil size, airflow, and mouthpiece change output.
• Use pattern: short sessions use less than long sessions.
• Leaks and clogs: oil lost to leaks does not produce vapor.

Draw estimate by use level

• 5 draws per day: 12 to 30 days at 60 to 150 total draws.
• 10 draws per day: 6 to 15 days.
• 20 draws per day: 3 to 7 days.
• 40 draws per day: 1 to 4 days.

How to make a cart last

1. Use low voltage. Start at the lowest setting that gives vapor.
2. Take draws of 2 to 3 seconds. Wait between draws.
3. Store upright at room temperature. Keep away from heat and sunlight.
4. Cap the mouthpiece when not in use.
5. Do not pull hard on a clogged cart. Warm it in your hand or use a preheat function.

When a cart is empty

Vapor drops, taste changes, and oil no longer covers the intake holes. A cart can look empty and still hold oil near the coil. Stop when vapor turns harsh or the cart tastes burnt. A burnt coil can add bad taste to later draws.

Dose and safety

Cart labels list THC and CBD content. A 500 mg cart with 80% THC holds about 400 mg THC total. A single draw may deliver 1 to 5 mg THC, based on device and oil. New users should start with one short draw and wait 15 minutes. Cannabis can impair coordination and driving. Do not drive after use. CDC reports that THC-containing vaping products from informal sources have been linked to lung injury. Buy from licensed stores and check labels.
