The treatment used to help smokers stop smoking is called nicotine replacement therapy. Here, products that deliver low doses of nicotine are used, but they do not contain other toxins found in a cigarette. The aim of this treatment is to cut smokers' cravings for nicotine and reduce the symptoms of nicotine withdrawal, such as sweating, tingling in hands and feet, sore throat, anxiety, irritability, headaches, etc.
