What a cannabis disposable vape is

A cannabis disposable vape is a sealed device that holds THC oil and a battery in one unit. The user inhales. The device heats the oil. The unit does not refill. When the oil runs out or the battery dies, the unit is spent. Brands sell them in 0.5 g, 1 g, and 2 g sizes. Most run at a fixed voltage between 3.0 V and 3.7 V.

How the device works

Inside the housing sits a lithium-ion cell, a wick made of ceramic or cotton, and a coil. The battery feeds the coil. The coil turns the oil into vapor. Some devices have a button. Others are draw-activated, which means the coil fires when the user pulls air. Fixed voltage means the user cannot change temperature. Rechargeable models add a USB-C port. Models without a port stop working when the cell drains.

Sizes, potency, and puff counts

Potency depends on the oil. Distillate tests between 70% and 90% THC. Live resin and rosin test between 60% and 80% THC and hold more plant terpenes. A 1 g device holds about 1,000 mg of oil. Puff counts come from the maker, not from a standard. A 0.5 g distillate device lists 300 to 600 puffs. Battery capacity runs 280 mAh to 350 mAh.

Reading the label

State rules require lab testing for pesticides, heavy metals, residual solvents, and microbials. Ask for the certificate of analysis if the package does not list results. A COA names the lab, the test method, and a pass or fail result for each panel.

Storage and use

Store the device upright at room temperature. Heat thins the oil and can cause leaks. Cold thickens the oil and clogs the wick. Keep it away from direct sunlight. A clogged device may clear with a preheat cycle or with two short draws. Do not pull hard, because that floods the coil. A 1 g device lasts one to three weeks for a user who takes 10 to 20 puffs a day.

Cost

Prices move with state supply and brand. In 2024, a 1 g distillate disposable in California or Michigan sold for $20 to $45 before tax. Live resin versions sold for $35 to $70. State and local taxes add 15% to 35% on top of the shelf price.

Legality in the US

Cannabis is a Schedule I substance under federal law. Disposable vape sales are legal inside state-licensed programs. Outside those programs they are not. Recreational states set the purchase age at 21. Some medical states allow 18 with a patient card. Transport across state lines is illegal, and airport security follows federal rules.

Disposal

The housing contains a lithium-ion cell. Lithium batteries do not belong in household trash or curbside bins. Take spent devices to a household hazardous waste site or a battery recycler. Some states run take-back programs at dispensaries. State environmental agencies publish drop-off lists.
