There are many ways to stop smoking. Working with an addiction specialist can help you develop a plan that will work best for you. In this JAMA report, verenicline helps some patients, but I also have found patients who used other ways to successfully quit and who didn't like the side effects of verenicline. The important thing to know is that there are many ways to quit and the chance of success increases with each attempt. So, the motto I like the best is, "don't quit trying to quit."
