The experts in the camps say strong willpower is not enough for quitters.

Professor Lin Jiangtao, Respiratory Medicine Dept. of China-Japan Friendship Hospital, said, "Smokers with severe dependence should apply comprehensive habit-breaking methods. Besides behavior and psychological therapies, sometimes medical treatment is necessary. The medicine can relieve the symptoms while trying to break their habit, and increase the chance of success."

The experts also say tobacco addiction is not only a bad habit, but a serious chronic disease. Only 3 percent of people who quit smoking can stop for a year and not smoke again without medicine. They suggest that people wishing to quit should go to hospitals for professional instruction and treatment.
