FDA has not approved e-cigarettes as smoking aids. However, a recent CDC study found that many adults are using e-cigarettes to quit smoking.

In the United States, the youth are more likely than adults to use e-cigarettes. Among current adult e-cigarette users, the percentage who have never smoked cigarettes is highest among those aged 18–24 years (56.0%) and is lower in older age groups.
