A shot that robs smokers of the nicotine buzz from cigarettes showed promise in midstage testing and may someday offer a radically new way to kick a dangerous habit. In a study, more than twice as many people given five of the shots stopped smoking than those given fewer or phony shots Â about 15 percent versus 6 percent after one year.
