Many smokers find it difficult to quit. People commonly quit smoking and then find themselves smoking again, especially in the first few weeks or months after quitting.
People who smoke after quitting should try again to quit.
Most people find that they need to persist in their attempts to quit smoking before they quit for good. It may take four or more attempts before smokers are able to quit for good.
People who stop smoking for 3 months or longer have an excellent chance of remaining cigarette free for the rest of their lives.
