["New approaches and new methods for preventing smoking among adolescents"].

"New approaches and new methods for preventing smoking among adolescents .The design of smoking prevention programs requires a good understanding of the network of influences leading to smoking, whether they are developmental, physiological, psychological, sociological or economic in nature. Prevention programs also need to be rigorously evaluated and then scaled up to benefit as many people as possible. Choosing the most efficient programs would yield a significant return on investment for individuals and society, given the enormous cost of smoking. Regulatory preventive interventions, in schools or in healthcare, in the family environment and media campaigns have shown their interest, and sometimes have been associated with an interesting return on investment. Examples are given, in particular of programs available on French territory. The main challenge is that the overall strategy has a proportionate universalism approach, that is to say a prevention for all, but adapted to the needs and specificities of each category (level of education, gender, etc.)."
