Missouri’s approach to regulating vaping products, including e-cigarettes, vape pens, and e-liquids, presents a unique and complex legal landscape. Compared to many other states, Missouri maintains a relatively permissive framework at the state level, characterized by a lack of specific excise taxes on vapes and no comprehensive statewide ban on vaping in public indoor spaces. However, this state-level leniency is contrasted by strict federal age requirements, a patchwork of robust local ordinances, and significant pending legislation that could dramatically reshape the market.
