Metali poput nikla, hroma i olova, koji se smatraju kancerogenim, takođe su detektovani u aerosolu e-cigareta, a zabrinjava i činjenica da koncentracija nikla može biti i veća u poređenju sa duvanskim dimom” – navedeno je u tekstu Sandre Vezmar Kovačević, profesorke Farmaceutskog fakulteta u Beogradu.

Odluka dolazi usred sve većeg broja dokaza da izlaganje iz druge ruke – aerosolima e-cigareta, sa i bez nikotina, izlaže prolaznike merljivim nivoima čestica i ključnih toksičnih i zagađujućih supstanci – kaže se u nacrtu.
Kao sto je to slučaj s alkoholizmom, odnos društva i nikotinizma je toliko kompleksan da je često uzrok sukobljavanja različitih interesa.

kod IQOS-a nikotin se dobija prirodnim putem, zagrevanjem duvana, a kod e-cigareta je ekstrahovan u tečnosti i može biti dobijen i iz drugih izvora,
Basic molecular representation of cellulose acetate with one of many acetate groups over the cellulose spine proven via the purple circle Cigarette filters are made up of Countless polymer chains of cellulose acetate, which has the chemical composition proven to the proper. As soon as discarded into your natural environment, the filters produce a big squander issue.
Smoking can raise your threat for periodontal condition or ailment impacting the gums. This comes about since smoking cigarettes will cause inflammation within the teeth and increases your risk for bacterial infections.

The secondary mechanisms could be the addition of the compound into the filters that will have the capacity to take in normal light-weight and use it to begin the degradation course of action. The primary two regions of exploration are in photocatalytic oxidation[188] and photosensitized degradation.[189] Photocatalytic oxidation utilizes a species that absorbs radiation and generates hydroxyl radicals that respond Using the filters and start the breakdown. Photosensitized degradation, however, takes advantage of a species that absorbs radiation and transfers the Strength to the cellulose acetate to begin the degradation approach. Both processes use other species that absorbed mild > three hundred nm to get started on the degradation of cellulose acetate.[citation needed]
