Interventions

Smoking reduction intervention BEHAVIORAL

Smokers was informed that many harmful effects were proved to be related with smoking, such as cancer, coronary heart disease, respiratory disease and many other health problems, and one out of two smokers will be killed by smoking. Smokers will be advised to reduce smoking consumption for at least half of their total consumption in the next month. Finally, all smokers were warned to keep in mind that the current attempt to reduce smoking is an intermediate step before the complete cessation.
