Tomorrow Will Be Smoke-Free (DNF) is an association recognized as serving the public interest, founded in 1973, committed to protecting against tobacco use. Our work operates at the intersection of public health, social issues, and the environmental impacts of tobacco. We pursue this through advocacy, awareness-raising, and support for public policy, drawing on expertise in health, social affairs, and the environment. For over fifty years, DNF has contributed to several major advances in France's fight against tobacco, including the Évin Law, plain packaging, and strengthened taxation of tobacco products. We are currently leading the research program "My Terrace Smoke-Free" (2026–2027), supported by the Fund for Combating Addictions. It evaluates the social, environmental, and economic impacts of implementing smoke-free terraces in the HoReCa sector (hotels, restaurants, cafés), through three complementary study components.
