Non-industrialized nations also will be hit hard by the epidemic. WHO organized a smoking cessation campaign in 1996 which registered 70,000 smokers from 24 countries and directed a conference on alcohol dependence with participants from 46 countries. The group is promoting a global campaign to encourage healthy lifestyles, with an emphasis on the healthy development of children and adolescents in relation to risk factors such as diet, exercise, and smoking.
