Nicotine replacement therapy (NRT) works by substituting the source of nicotine to “replace” the nicotine you inhale when you smoke. For people who are quitting smoking, NRTs can help by delivering a safer alternative source of nicotine than cigarettes. They also can reduce or eliminate the symptoms of withdrawal, making it easier for some people to quit. NRTs have been extensively tested and used by millions of people. They are considered safe and effective ways of quitting smoking.
