Public health; eliminating certain preemption; authorizing adoption of certain regulations. Effective date.

SB 337 amends Oklahoma's public health law to allow cities and towns to adopt stricter smoking and vaping regulations than the state, while preventing local rules from being weaker than state standards. It expands the existing law to cover vapor products (like e-cigarettes) in public places and properties owned by local governments. The bill removes a previous state preemption that limited local authority, enabling more protective local measures without conflicting with state law. The law takes effect on November 1, 2025.
