Nicotine Patches and Gum Found Ineffective Over the Long Term
A study in the journal Tobacco Control casting doubt on the effectiveness of nicotine replacement therapy has garnered widespread media attention.
Over several years, researchers followed some 800 smokers after they quit. By 2 years, relapse rates were the same among people who had and had not used nicotine replacement (with or without counseling), according to news reports. At 4 years, two thirds of participants were smoking again.
The therapies were the centerpiece of a state-sponsored program to encourage quitting in Massachusetts, but, according to a study coauthor quoted in the Boston Globe, "what we found is that they have absolutely no effect." The New York Times quotes another of the study's authors as observing that "what happens in the real world is very different" from what happens in clinical trials.
