Modifies provisions relating to tobacco product regulations

SB 1064 prevents Missouri cities and counties from creating stricter regulations than the state for tobacco, nicotine, and vaping products. It blocks local bans on products, ingredient rules, or sales licensing but allows existing local age-21 sales laws to remain in effect. Local governments can maintain current rules until January 1, 2026, but any new regulations after that date must follow state law. This directly affects how local jurisdictions can regulate the sale of these products.
