Key Resources on E-Cigarettes and Vaping

What We Know

  • E-cigarettes are not safe for youth.1
  • In 2021, over 1.7 million high school students and over 300,000 middle school students nationwide reported current e-cigarette use.2
  • In the United States, youth are more likely to use e-cigarettes or vapes compared to adults.3
  • Nicotine is the primary agent in both regular cigarettes and e-cigarettes, and there's nicotine in most flavored e-cigarettes.​ 
  • Nicotine is addictive and can harm adolescent brain development, which continues into the early to mid-20s, negatively impacting memory, learning, and attention.1   
  • Young adults who use e-cigarettes are four times more likely to begin smoking regular cigarettes within 18 months compared to those who do not use e-cigarettes.​4
  • E-cigarettes produce a chemical-filled aerosol, not 'harmless' water vapor.1 
  • Chemicals in e-cigarette aerosol include nicotine, acetone, and ultrafine particles that should not be inhaled into the lungs.1
  • Chemicals are added to e-cigarettes for flavoring. Diacetyl, a chemical detected in many e-cigarettes, can cause severe lung disease when inhaled.5
  • E-cigarettes are not FDA approved as a quit smoking aid, and there is limited evidence in their effectiveness in helping people who smoke​ to quit.6​
