Mississippi Smoke-Free Air Act of 2026; create.

HB 253, the Mississippi Smoke-Free Air Act of 2026, bans smoking in enclosed public places (like restaurants and bars), workplaces, private clubs, residential facilities, and certain outdoor areas (such as outdoor dining). It requires businesses to post "no smoking" signs at entrances and allows voluntary smoke-free designations. The law repeals Mississippi’s previous Clean Indoor Air Act and directs the State Department of Health to educate the public and businesses on compliance. It directly affects owners, operators, and employees of venues covered by the ban, aiming to eliminate secondhand smoke exposure in these settings.
