The medical consequences of tobacco use-including second-hand exposure-make tobacco control and smoking prevention crucial parts of any public health strategy. Since the first Surgeon General’s Report on Smoking and Health in 1964, states and communities have made efforts to reduce the initiation of smoking, decrease exposure to smoke, and increase cessation. Researchers estimate that these tobacco control efforts are associated with averting an estimated 8 million premature deaths and extending the average life expectancy of men by 2.3 years and of women by 1.6 years. But there is a long way yet to go: Roughly 5.6 million adolescents under age 18 are expected to die prematurely as a result of an illness related to smoking.

Prevention

Prevention can take the form of policy-level measures, such as increased taxation of tobacco products; stricter laws (and enforcement of laws) regulating who can purchase tobacco products; how and where they can be purchased; where and when they can be used (i.e., smoke-free policies in restaurants, bars, and other public places); and restrictions on advertising and mandatory health warnings on packages. Over 100 studies have shown that higher taxes on cigarettes, for example, produce significant reductions in smoking, especially among youth and lower-income individuals. Smoke-free workplace laws and restrictions on advertising have also shown benefits.

Prevention can also take place at the school or community level. Merely educating potential smokers about the health risks has not proven effective. Successful evidence-based interventions aim to reduce or delay initiation of smoking, alcohol use, and illicit drug use, and otherwise improve outcomes for children and teens by reducing or mitigating modifiable risk factors and bolstering protective factors. Risk factors for smoking include having family members or peers who smoke, being in a lower socioeconomic status, living in a neighbourhood with high density of tobacco outlets, not participating in team sports, being exposed to smoking in movies, and being sensation-seeking. Although older teens are more likely to smoke than younger teens, the earlier a person starts smoking or using any addictive substance, the more likely they are to develop an addiction. Males are also more likely to take up smoking in adolescence than females.
