Can You Vape in Missouri? 2026 Laws, No Vape Tax & Local Bans

Missouri has no statewide indoor vaping ban, no flavor ban, and no excise tax on vapor products. It's one of the most permissive states for vapers. But 19+ municipalities including St. Louis and Kansas City ban indoor vaping locally, and federal T21 law means you still need to be 21+ to buy.
