Washington, Oct 2 : A new study has uncovered the mechanism behind smokers’ persistent dependency on nicotine.

Researchers at the Scripps Research Koob lab found that, in rats, chronic nicotine use recruits the extrahypothalamic corticotropin releasing factor (CRF) system, a major brain stress system, which contributes to continued tobacco use by intensifying anxiety and craving upon withdrawal.

The researchers pointed out that their findings might help explain why many cigarette smokers relapse even after a long abstinence from smoking.
