There is even more reason now to avoid secondhand smoke.

A new study shows secondhand smoke triggers cravings for nicotine and makes it harder for smokers to kick the habit.

Researchers say secondhand smoke has a direct and measurable impact on the brain similar to that of actually smoking.

The findings underscore previous research suggesting exposure to secondhand smoke increases a child's chances of becoming a smoker later in life.

The study was funded by the U.S. National Institute on Drug Abuse.
