How do nicotine patches help in smoking cessation?
Nicotine patches, as well as nicotine-containing gums and other types of smoking-replacement therapies, are used to ensure a constant supply of reduced doses of nicotine into the system of an ex-smoker, in order to help him cope with acute and highly unpleasant symptoms of tobacco withdrawal. Nicotine patches work as a medication that contains small doses of nicotine but free from other harmful chemicals found in tobacco smoke. Tobacco-replacement therapies help people overcome physiological dependency on tobacco, but they do not address psychological addiction to smoking.
