How a cannabis vape pen works

A cannabis vape pen turns THC oil into an aerosol you inhale. A battery sends current to a coil inside the cartridge. The coil heats the oil past its boiling point. The oil becomes vapor, airflow carries it through a channel to the mouthpiece, and you pull it into your lungs. Nothing burns. There is no flame, no ash, and no smoke, which is why the vapor tastes like the oil rather than like a campfire.

The parts of a vape pen

• Battery: a rechargeable lithium cell. Button models fire when you hold the button. Draw-activated models fire when you pull air.
• Cartridge or pod: the tank that holds the oil. Most hold 0.5 to 1 gram.
• Coil and wick: the heating element. Ceramic and quartz handle high heat. Cotton works on lower power.
• Mouthpiece: the tip you draw from. It also shapes airflow.
• Airflow channel: the path air takes from the intake hole, past the coil, and out the mouthpiece.

What happens on each puff

1. You press the button or pull air through the mouthpiece. The battery closes the circuit.
2. Current flows to the coil and heats it. Most coils reach working temperature in one to two seconds.
3. Heat moves into the oil through the wick or the porous ceramic core.
4. The oil vaporizes. Cannabinoids such as THC boil between roughly 315 F and 390 F.
5. Fresh air enters the intake holes and pushes the vapor up the channel.
6. The vapor cools as it travels and reaches your lungs as a fine mist.
7. THC crosses the lung lining into the blood and reaches the brain within seconds to minutes.

Voltage and heat

Most batteries run from 2.5 to 4.8 volts. Low settings near 2.8 volts protect terpenes and give a lighter hit. Mid settings near 3.4 volts balance flavor and vapor. High settings above 4 volts produce a thick cloud, but they burn terpenes and can scorch the coil. A scorched coil gives every later puff a burnt taste, so it pays to start low.

Why oils behave differently

Distillate is THC stripped of most other compounds. It is thick and runs best at medium heat. Live resin and full-spectrum oils keep terpenes and other cannabinoids, and they taste better at low heat. Terpenes thin the oil, so a runny cartridge needs less power. Cold weather makes oil thick, and a cartridge that will not pull in winter may just need a few seconds of warmth from your hand.

Before you use a pen

• Confirm the cartridge comes from a licensed dispensary and carries a batch label.
• Check the threading. A 510 cart fits most batteries. A pod fits only its own device.
• Charge the battery. Most pens use USB or a magnetic charger.
• Prime a new cartridge with two short draws while the button stays off.

Timing and dose

Inhaled THC acts fast. A single two to three second draw can show effects in under five minutes. Wait ten to fifteen minutes before you take another. Vaping delivers more THC per puff than smoking flower, so new users do best with one small draw and a long pause. Store cartridges upright, away from heat and sunlight.

Safety note

Legal, tested cartridges from licensed shops differ from unregulated ones. Vitamin E acetate, a thickening agent found in some illicit THC carts, was linked to the 2019 EVALI outbreak. If a cartridge has no label, no batch number, or no source you can verify, leave it alone.
