Health Information

E-cigarettes have not been fully studied, so consumers currently don’t know:

the potential risks of e-cigarettes when used as intended,
how much nicotine or other potentially harmful chemicals are being inhaled during use, or
whether there are any benefits associated with using these products.

Additionally, it is not known whether e-cigarettes may lead young people to try other tobacco products, including conventional cigarettes, which are known to cause disease and lead to premature death.

eCigarettes and Adverse Events

What is an Adverse Event?
An adverse event is an undesirable side effect or unexpected health or product quality problem that an individual believes was caused by the use of a tobacco product.

The FDA has received reports of adverse events involving e-cigarettes from consumers, health professionals and concerned members of the public. The adverse events described in these reports have included hospitalization for illnesses such as

pneumonia,
congestive heart failure,
disorientation,
seizure,
hypotension, and
other health problems.

Whether e-cigarettes caused these reported adverse events is unknown. Some of the adverse events could be related to a pre-existing medical condition or to other causes that were not reported to FDA.
