Bans Don't Help Smokers Kick The Butt: Study

"People might be sensitive to the issues, but there was a lack of information about how the effects of second-hand smoke are transmitted," said Kairouz.

Greater inspiration to kick the habit likely comes from having friends or family who set an example by giving up cigarettes themselves, researchers said.

But trends over the past decade suggest a much broader range of factors have reduced the number of nicotine addicts beyond simply forcing smokers to huddle outdoors more often.

"There needs to be an integrated approach of ecological measures along with taxation, prevention and information," Kairouz said.

"But one of the most important components is to have public health services available for people who are trying to quit," Kairouz added.

The research was published in the journal Nicotine and Tobacco Research.
