Drug could help women quit smoking

Researchers at the University of Chicago are studying whether an anti-addiction drug will help women stop smoking.

The drug is called naltrexone by manufacturer Alkermes. Naltrexone has already been approved to treat alcoholism and heroin addiction.

Monday's Sun-Times reports that U of C researchers theorize it may also help women smokers. They often have trouble quitting because they fear gaining weight, and because they are more prone to depression than men.
