Known Health Effects of E-Cigarette Use (March 2019)


This issue brief, the second of a two-part series, examines the latest research concerning the health effects of e-cigarettes. It examines the chemical components, human health consequences, effects on initiation and cessation of conventional tobacco cigarette use, and harm reduction.

Key points from the brief include:

  • A 2018 report by the National Academies of Science, Engineering, and Medicine (NASEM) concluded there is substantial evidence e-cigarette use increases the risk of ever using conventional cigarettes among youth and young adults.
  • The NASEM report also found:
    • Moderate evidence that more frequent use of e-cigarettes is associated with an increased likelihood of cessation of conventional cigarettes,
    • Limited evidence that e-cigarettes may be effective aids to promote smoking cessation,
    • Conclusive evidence that e-cigarette use increases airborne concentrations of particulate matter and nicotine in indoor environments compared with background levels,
    • Conclusive evidence that most e-cigarette products, in addition to nicotine, contain and emit numerous potentially toxic substances, and
    • Evidence on short-term exposure to e-cigarettes and health effects exists, but is not conclusive.
