Statewide Ban on Smoking in Cars with Kids? 

A pair of identical bills that would ban smoking in cars when children are present goes before the Maine Legislature on Tuesday.
The measure, which is aimed at protecting kids from secondhand
smoke, is modeled after a year-old ordinance in Bangor. Three other
states have similar bans.
The proposal has the backing of the American Lung Association of
Maine, and Gov. John Baldacci has signaled that he’s likely to
support it.
For their part, tobacco companies say they’re not planning to
fight the measure. Instead, opposition could come from civil
libertarians, who’ve expressed concerns about what some regard as
excessive government intrusion in people’s lives.
