Mississippi

Mississippi is one of only three states nationwide without any restrictions on smoking at child-care facilities. While the state has banned smoking in government buildings and on college campuses, a recent proposal for a broader ruling didn't meet with much approval.

Supporters were looking to ban smoking in restaurants and nongovernment buildings, but the proposal fell apart in March. Opponents argued that the government shouldn't tell private businesses how to operate. But it may be even more simple: Some residents told local newscasters they wouldn't want to stop lighting up when they're out and about.
