Some individuals carry a gene variant that may help protect them from becoming addicted to nicotine, according to a new study funded in part by the National Institute on Drug Abuse, National Institutes of Health, and published in the June 25 issue of Nature. The study found that individuals with a genetic variant in a particular enzyme break nicotine more slowly than those who do not. They have greater resistance to nicotine addiction and, if they do smoke, they smoke fewer cigarettes than individuals without the impairment.
