A DNA test could spot which smokers have an addictive gene and how best to help them, say scientists.

WASHINGTON - California researchers fiddled with a single gene to create mice hypersensitive to nicotine, pointing to a single molecule partly to blame for nicotineâs addictive allure.

The finding was made by breeding mice that lacked specific receptor subunits and testing their response to nicotine. Mice lacking the subunit designated beta2 had reduced sensitivity to nicotine

Gene variants that lead to  decreased amounts of an enzyme known as GSTM1 may raise the  risk of lung cancer related to radon exposure, new research  suggests. The gene variants also seem to increase the  cancer-causing effect of secondhand smoke.

Kicking the tobacco habit, even young, does not always reset harmful cancer-related genes that have been switched on or off by smoking in the first place, according to a study to be published Thursday.
