WASHINGTON (AP) - A single pill appears to hold promise in curbing the urges to both smoke and drink, according to researchers trying to help people overcome addiction by targeting a pleasure center in the brain.
The drug, called varenicline, already is sold to help smokers kick the habit. New but preliminary research suggests it could gain a second use in helping heavy drinkers quit, too.
Much further down the line, the tablets might be considered as a treatment for addictions to everything from gambling to painkillers, researchers said.
