Quitting smoking is a difficult and long process, although only one cigarette is smoked on the way to quit smoking, but it is also considered a relapse, it is recommended that when you want to smoke, you can find something else to do, so that the desire to smoke is reduced, such as chatting, reading books, taking a walk and so on. Long-term smokers tend to become addicted to tobacco, and this addiction lies in the addiction to nicotine. Successful quitters can overcome the symptoms caused by nicotine addiction relatively smoothly. In the process of quitting smoking, if occasionally because of an opportunity to go back to smoking, it is easy to cause the failure of quitting smoking. This is because getting nicotine again may cause the addiction to intensify, making the quit a failure. It is advisable to seek professional help at a smoking cessation clinic when relapse occurs.
