List of vaping bans in the United States
Laws regulating the use of electronic cigarettes, also known as "vaping", vary across the United States. Some states and municipalities prohibit vaping in every location where smoking is prohibited, while others contain more permissive laws or no laws at all regarding vaping.

Indoor bans

In August 2016, a World Health Organization (WHO) report recommended that e-cigarettes be banned in indoor areas or where smoking is prohibited. This is because of their potential for non-users to be exposed to chemicals and e-cigarette aerosol in indoor areas. Many local and state jurisdictions have recently begun enacting laws that prohibit e-cigarette usage everywhere that smoking is banned, although some state laws with comprehensive smoke-free laws will still allow for vaping to be permitted in bars and restaurants while prohibiting e-cigarettes in other indoor places. The only states that do not regulate indoor vaping at all, be it by state territory or on a local level, are in the states of Nebraska, Nevada, and Tennessee.
