The Missouri House of Representatives has approved a bill that would prevent local governments from enforcing tobacco and nicotine sales rules stricter than those set by the state.

The legislation, sponsored by Rep. Ben Keathley, aims to standardize nicotine regulations statewide. It would block municipalities from enacting measures such as bans on flavored tobacco and vaping products—rules often criticized by some lawmakers as overly restrictive.

The proposal also includes a provision to raise Missouri’s legal nicotine product purchasing age to 21, aligning state law with existing federal standards.

Supporters argue the bill ensures consistency for retailers across the state, while critics warn it could strip cities of the ability to address public health concerns in their own communities.

The measure now moves to the Missouri Senate for consideration.
