E-cigarettes aren’t harmless. Though marketed as safer alternatives to smoking, they release toxic chemicals that can damage the lungs and heart.
What the Science Says
A 2018 report from the National Academies reviewed 800+ studies and confirmed:
E-cigarettes pose real health risks.
They emit harmful substances and are linked to cough, wheezing, and asthma flare-ups, especially in youth.
What’s in the Vapor?
E-cigarettes produce:
- Diacetyl – linked to serious lung disease
- Acrolein – causes lung injury, COPD, and possibly cancer
- Formaldehyde – a known carcinogen
- Heavy metals – nickel, lead, tin
Even the basic ingredients (propylene glycol and vegetable glycerin) are toxic to lung cells, especially when combined with flavorings.
Secondhand Vape = Secondhand Harm
Secondhand vapor contains:
- Nicotine
- Ultrafine particles
- Toxic chemicals like benzene, diacetyl, and metals
Bottom line:
E-cigarettes are not safe. They harm lungs, worsen asthma, and expose even non-users to dangerous chemicals. Don’t be misled by the vapor—the risks are real.
