The FDA does not approve vaping as a way for people to stop smoking. Other methods, like nicotine replacement therapy, are recommended. Dr. Chiarchiaro advises talking to your doctor about other methods to quit smoking before trying e-cigarettes. You also can call the national hotline, 1-800-784-8669 (1-800-QUIT-NOW), for help. “There are some really well-tested methods to help people stop smoking,” Dr. Chiarchiaro says.
