Is vaping without nicotine bad for you?
That sounds concerning. What are formaldehyde and acrolein, and why are they harmful?
Formaldehyde is a colorless gas that is used in many industrial applications and is known to cause cancer in humans. Acrolein is a toxic, irritant gas that is used in the production of plastics and can cause respiratory damage. Both formaldehyde and acrolein can be formed when e-liquids are heated, which is why some experts are concerned about the potential health effects of vaping.
