E-liquid

What’s in e-liquid (e-juice)?

E-liquid, also called e-juice or vape juice, is what vaping devices use to make the vapor you breathe in. E-liquids aren’t just water. They usually contain:

• Flavoring. Each flavoring has its own set of ingredients.

• Nicotine, the addictive and harmful substance in cigarettes and other tobacco products.

• Propylene glycol and glycerin, used to create vapor.

E-liquids and flavorings sometimes have other ingredients, including:

• Chemicals that can cause cancer (carcinogens), like acetaldehyde and formaldehyde.

• Chemicals known to cause lung disease, such as acrolein, diacetyl and diethylene glycol.

• THC (tetrahydrocannabinol), the chemical in marijuana that gets you “high.”

• Vitamin E acetate, linked to lung injury caused by vaping (EVALI, see below).

• Heavy metals like nickel, tin, lead and cadmium.

• Tiny (ultrafine) particles that can get deep into your lungs.
