[Beauty and smoking: the utilization of public health programs in the prevention of tobacco use disorders].

Research in tobacco prevention is increasingly showing that anti-smoking campaigns aimed at youth work. However, not all interventions are effective, and some have had unintended harmful effects, even to the point of increasing tobacco use by youth. In this commentary, we discuss potentials risks associated with interventions poorly supported by the evidence, using the example of tobacco prevention campaigns that focus on the effects of smoking on beauty. We conclude with two points: 1) the importance of using strategies based on evidence, and 2) the importance of rigorous evaluation of innovative strategies.
