It looks like Canadians are on the bandwagon with several states in the U.S. in the war against smoking. Authorities in Ontario are moving to ban smoking in cars when children are present.

Offenders will be fined $247 if caught in the act of smoking with a child present in the car, even if the windows are rolled down. The law was presented Wednesday and is under consideration.

According to California's Air Resources Board, second-hand smoke can be as many as 27 times more concentrated than in the home. Arkansas, California, Louisiana, Maine and Puerto Rico, among others, already have similar bans in place.
