New vapes produce formaldehyde (what they use to preserve dead bodies), acetone (nail polish remover and paint thinner), acetaldehyde (a chemical in glue), and other carcinogens in their vapor, which goes into your lungs. 1,2

Dangerous metal particles such as chromium are found in vape clouds and the toxic metal can build in your lungs over time.3,4

Newer vapes combine freebase nicotine with benzoic acid to create a stronger nicotine hit.1,5,6,7,11

Juul’s own patent states: “[N]icotine salt formulations provide satisfaction … comparable to smoking a traditional cigarette.”5

The nicotine you get in one vape pod can be as much as an entire pack of cigarettes.1,6,8,10,12

Vapes can emit as many as 31 different chemicals like formaldehyde.2

One 5% pod can have as much nicotine as an entire pack of cigarettes.1,6,8,10,12

One 3% vape pod contains 23mg of nicotine.6

One 5% vape pod contains about 40mg of nicotine.6

Heavy nicotine use can prime adolescent brains for future substance use.9

Studies have detected formaldehyde in vape aerosols operating at as low as 5W battery output.13,14

In a study using human embryonic kidney cells, researchers found that vanilla vape flavoring kicks off a process that can cause cell death and change how the cells in your body reproduce. 15

One study found that exposure to the following e-liquid flavors resulted in dramatic facial deformities in tadpoles: Strawberry, Almond, Caramel, Vanilla, Biscuit, and Vienna Cream; Cereal, Berries, Cream, and Citrus.16

Vanilla and Cinnamon flavors are a type of chemical called an aldehyde, they belong to the same chemical class as formaldehyde. 17

Diacetyl is a chemical that gives certain vape flavors their buttery flavoring, and is known to cause an irreversible, and chronic lung condition known as "popcorn lung" when inhaled at high doses.18,19

Nicotine is highly addictive, especially for adolescents, and has been found to affect adolescent brain development.20
