"Women have historically not responded as well as men to smoking-cessation treatment, so treatment strategies that show promise with helping them are very interesting," said study author Andrea King, an associate professor of psychiatry at the University of Chicago.
The study authors noted that naltrexone is thought to reduce cigarette and alcohol craving by blocking drug-induced brain signals that convey pleasure.
King and her colleagues studied the potential benefits of the drug among 110 men and women who smoked between 15 and 40 cigarettes a day for an average of 25 years.

"This is a treatment option that needs more study, but I am optimistic," said King."And, in the end, it may be that this kind of aggressive treatment somehow addresses both psychological and biological issues that are at play which could account for the complexities of smoking as they specifically relate to women."
King said she's now conducting a study that's three times larger than the first one.She hopes it will help unravel the mechanisms that underlie the drug's affect.
