The concept of 'safe cigarette'

Abstract

In the production of the so−called "safe cigarette", attention has been focused so far on the particle phase of tobacco smoke and possibilities of reducing its harmful components (tar, nicotine and PAHs). CO, an element of the gas phase of tobacco smoke, is still considered a minor by−product. The exploited technical and technological solutions concentrate on nonselective removal of the particle phase (filtration and perforations of cigarette paper). However, these solutions face numerous technological limitations such as suction resistance in the case of filtration and tearing resistance in the case of paper perforations. Methods based on tobacco smoke modification by selective removal of undesirable components are still in pilot phase. Such methods, aimed at reduced generation of harmful components, involve changes in combustion conditions and temperature achieved by adding specially synthesized catalysts into the tobacco blend. The active surfaces of these catalysts adsorb the already formed undesirable components of tobacco smoke.

Prema najnovijim podacima više od 1 svetske populacije konzumira cigarete (oko 1,7 milijardi ljudi). Dnevna potrošnja cigareta u svetu je oko 16,5 milijardi komada. Obzirom da konzumiranje cigareta raste iz godine u godinu novi zakonski propisi u proizvodnji cigareta nameću sve rigoroznije zahteve u pogledu materija štetnih po zdravlje u duvanskom dimu. Ovaj rad ima za cilj da se našoj naučnoj i stručnoj javnosti prezentiraju rezultati, koji se kod nas i u svetu postižu u cilju smanjenja štetnih efekata duvanskog dima cigarete. Rad se bazira na literaturi koja se bavi elementima štetnosti duvanskog dima po zdravlje aktivnih i pasivnih pušača, kao mogućnošću smanjenja štetnih elemenata duvanskog dima cigareta.
