The bottom line

  • No tobacco products, including e-cigarettes, are safe.
  • E-cigarettes should not be used by youth, young adults, or people who are pregnant.
  • Adults who have never smoked or used other tobacco products, including e-cigarettes, should not start.
  • E-cigarettes may have the potential to benefit adults who smoke and are not pregnant if they are used as a complete substitute for smoked tobacco products. However, no e-cigarette has been approved by the FDA as a smoking cessation aid.
  • More research is needed to better understand the short- and long-term health effects of using e-cigarettes as well as whether e-cigarettes can be effective at helping adults quit smoking.
