All tobacco products contain substantial amounts of nicotine, which is absorbed readily from tobacco smoke in the lungs and from smokeless tobacco in the mouth or nose. Experts in the field of substance abuse consider tobacco dependence to be as strong or stronger than dependence on such substances as heroin or cocaine. Smoking typically begins in adolescence. If a person remains smoke-free throughout adolescence, it is highly unlikely that he or she will ever begin smoking. Therefore, it is vital that intensive efforts be made to help young people stay smoke-free.
Nicotine dependence is clearly a major barrier to successful cessation.
S moking control policies should contain strategies to strengthen smokers' motivation to quit, such as health education, public information, price policies, smoke-free policies, and behavioural programmes. In addition, there is evidence to indicate that, where appropiate, the use of pharmacological treatments, particularly nicotine replacement products, can ease physical dependence-related difficulties for smokers who try to quit. Currently, only a few health professionals are trained in the treatment of tobacco dependence. Tobacco dependence is a serious public health problem which warrants serious attention if the epidemic of tobacco-related mortality and morbidity is to be reduced. There are many benefits of quitting smoking Smoking cessation has immediate and substantial health benefits, and dramatically reduces the risk of most smoking-related diseases.
