An anti-smoking movement that started in a tiny Nova Scotia town appears to be spreading across the country.

Last month, Wolfville became the first jurisdiction to ban smoking in cars when kids are riding along.

The province then followed the town's lead. Starting next month, it will be illegal for smokers in Nova Scotia to light up in a car when anyone under 18 is on board.

Now, New Brunswick has similar plans. Michael Murphy, the province's health minister, told CTV Halifax that he's concerned that the tobacco industry is targeting kids. He also said that New Brunswick residents may want to consider the possibility of a smoking ban in cars with kids.

Studies show that the concentration of toxins in a smoke-filled car is 23 times greater than a smoky bar. Yet, one in five children are exposed to smoke in a car on a regular basis.

British Columbia and the Yukon are considering similar legislation. Ontario politicians have also started to debate vehicle smoking bans.
