Adsorbent and absorbent microgranulated composition for extinguishing cigarettes, of the type having a microgranulated silica-based constituent and an additional constituent containing at least one substance effective in retaining the molecules of tobacco odours. The composition of the invention is characterized in that it consists of a mixture of said microgranule-based constituent selected for its properties of retention, through gas adsorption, of the molecules of tobacco odours on the cavity walls of said microporous-based constituent. The additional constituent which is also microgranulated, is selected for its properties of retention, through gas absorption by molecular inclusion, of tobacco odours in the cavities of the molecules of said additional constituent.
