Whats is vapes?

"Vapes" (also called e-cigarettes, vape pens, pods, or mods) are battery-powered devices that heat a liquid or concentrate until it turns into an aerosol that you inhale. That aerosol is often called "vapor," but it is not just water vapor-it contains fine particles, flavor chemicals, nicotine or THC/CBD, and sometimes metals or other contaminants.

How a vape works

Most vapes have:

A battery

A heating coil/atomizer

A cartridge, pod, or tank that holds the liquid or oil

A mouthpiece

When you puff or press the button, the coil heats the liquid, and you inhale the aerosol.

What vapes can contain

Nicotine – in freebase or salt form; highly addictive

THC/CBD – in cannabis oil carts or disposable cannabis vapes

PG/VG – propylene glycol and vegetable glycerin, the main base liquids

Flavorings and coolants – often food-safe but not approved for inhalation

Other additives – including terpenes, acids, or, in illicit carts, dangerous substances like vitamin E acetate

Common types

Disposables – pre-filled, throw away when empty

Pod systems – small, use replaceable or refillable pods

Vape pens – slim devices, often used for cannabis oil

Mods – larger, customizable, produce bigger clouds

Cart vapes – a battery plus a pre-filled cannabis or nicotine cartridge

What vaping does

If it has nicotine: head rush, dizziness, increased heart rate, and rapid addiction.

If it has THC: a cannabis high, plus possible anxiety, paranoia, or impaired coordination.

It can cause coughing, throat irritation, chest tightness, and lung inflammation.

It is linked to higher risks of asthma, COPD, and likely lung cancer, and illicit THC carts have caused EVALI, a severe and sometimes fatal lung injury.

Long-term effects are still being studied, but vaping is not harmless.

Bottom line

A vape is an electronic device that heats a liquid or oil into an aerosol you inhale. It may be nicotine, cannabis, or just flavoring-but it still exposes your lungs to chemicals and fine particles. If you don't already vape or smoke, the safest choice is not to start.
