[Old and new tobacco products].

Tobacco use is not just about manufactured cigarettes. Rolling tobacco, highly prized in the wake of price increases, is estimated to carry more toxic agents than its counterpart. This study shows that the use of cigar, pipe, cigarillos and narghile also leads to a cohort of pathologies similar to or more than what is known for smoking single cigarettes. Exotic, liquid or heated forms do just as much. The non-smoked tobacco, often fallen into disuse in France is very used in the United States and especially in Scandinavia. Denuded of inhaled products, it is often pointed as a form of reduction of smoking risks. Its use by athletes in all countries as a doping attitude, especially in ski disciplines, required a campaign of prevention within the federations concerned.
