The Swiss Association for Tobacco Control is the center of competence for tobacco prevention in Switzerland. As an umbrella organization for the promotion of non-smoking, it today comprises over 50 organizational members. AT Switzerland offers its members a broad network of experts and provides expertise on tobacco control and prevention. With evidence-based offers and the networking of the central actors, it is committed to a sustainably healthy and smoke-free Switzerland and at the same time offers the population a hand in quitting smoking and nicotine withdrawal.

An important field of action is the denormalization of the consumption of tobacco and nicotine products. This is because a large part of the population still regards the consumption of lethal tobacco and nicotine products as "normal". Furthermore, the protection of young people is at the center of its work and AT Switzerland would like to encourage smokers on their way to quitting smoking. Finally, AT Switzerland is very concerned to strengthen the protection of the population from passive smoke.
