Method of making a smoking composition

   
   

The present invention relates to smoking articles such as cigarettes, and in particular to catalytic systems containing metallic or carbonaceous particles that reduce the content of certain harmful or carcinogenic substances, including polyaromatic hydrocarbons, tobacco-specific nitrosamines, carbazole, phenol, and catechol, in mainstream cigarette smoke and in side stream cigarette smoke.

La présente invention concerne les articles de tabagisme tels que des cigarettes, et en particulier aux systèmes catalytiques contenant les particules métalliques ou carbonées qui réduisent la teneur de certaines substances nocives ou cancérogènes, y compris les hydrocarbures polyaromatiques, de nitrosamines tabac-spécifiques, de carbazol, de phénol, et de catéchol, dans la fumée traditionnelle de cigarette et dans la fumée latérale de cigarette de jet.
