Can you vape indoors in the USA?
Short answer
It depends on the state, the city and the venue — there is no national rule. Many state clean indoor air laws have been amended to cover e-cigarettes explicitly, some have not, and hundreds of cities add their own. Federal rules ban vaping on all commercial flights, in federal buildings and in public housing.

Smoke-free air law in the United States is state and local, and coverage is genuinely uneven. Many states prohibit smoking in all enclosed workplaces including bars and restaurants; some cover fewer venue types; a few have no comprehensive statewide law and leave it to cities.
Whether e-cigarettes are included depends entirely on how that jurisdiction's law is drafted. A large number of clean indoor air acts have been amended to cover vaping explicitly. Others still refer only to lighted tobacco products, which leaves vaping to the venue's discretion. You cannot infer one from the other, and a state that bans indoor smoking may not ban indoor vaping.
Cities and counties frequently go further than their state, and hundreds have. Some states preempt local tobacco regulation, freezing coverage at the state level. Which regime applies determines whether your city could have its own rule at all.
Federal rules apply regardless of state: vaping is prohibited on all US commercial flights, in federal buildings, and in public housing operated by public housing agencies under a HUD rule covering indoor areas and immediate surroundings.
Private rules are separate from law and are usually the binding constraint in practice. Landlords may prohibit vaping in a lease. Hotels charge cleaning fees. Employers may ban it on their property. Hospitals and universities are commonly entirely smoke- and vape-free campuses. Rental car companies charge for it. None of these depend on state law.
Schools treat vaping as a tobacco offense regardless of state law, and most have specific policies with substantial consequences.
The workable default: assume you may not vape indoors unless you have been told you may. Enforcement is usually by the venue rather than by police, but the social and contractual consequences — being asked to leave, a cleaning charge, a lease breach — are the ones you will actually encounter.

The structure of US smoke-free air law, the variation in whether e-cigarettes are covered, and state preemption are tracked by Americans for Nonsmokers' Rights; federal rules come from the Federal Register sources cited. We deliberately do not list which states include vaping in their indoor smoking bans, because coverage varies by city as well as state, laws are amended frequently, and a stale list would be worse than none. Check your state health department and your own city ordinance. Private venue rules are contractual and are not affected by any of this.
