An experimental drug called varenicline helps smokers kick the habit better than does bupropion, the only drug currently prescribed for the task, a U.S.-Norwegian team of researchers finds.

In two studies, the researchers gave 2,045 U.S. smokers a placebo, varenicline, or bupropion—marketed as Amfebutamone, Wellbutrin, or Zyban.
