Kada se upali cigareta, duvan sagoreva (gori) i proizvodi dim, koji sadrži na hiljade hemikalija. Kada jednom započne, sagorevanje je samoodrživ proces koji se nastavlja sve dok na raspolaganju ima dovoljno duvana (goriva) i kiseonika.
Tokom sagorevanja, temperatura na vrhu cigarete može da premaši 800 °C.
Visoka temperatura dovodi do stvaranja više od 6000 različitih hemikalija1,2, od kojih su mnoge štetne ili potencijalno štetne.
Eksperti za javno zdravlje su klasifikovali nekoliko sastojaka dima kao verovatne uzročnike oboljenja povezanih sa pušenjem, kao što su karcinom pluća, srčano oboljenje i emfizem.
Mnogi zdravstveni autoriteti, kao što su američka FDA, Ministarstvo zdravlja Kanade i SZO, razvile su liste prioriteta u kojima su navedene hemikalije koje se smatraju štetnim i potencijalno štetnim sastojcima (HPHC) 3,4.

About Harmful and Potentially Harmful Constituents (HPHCs)
HPHCs are chemicals or chemical compounds in tobacco products or tobacco smoke that cause or could cause harm to smokers or nonsmokers. The Food, Drug and Cosmetic Act (FD&C Act) requires tobacco manufacturers and importers to report the levels of harmful and potentially harmful constituents (HPHCs) found in their tobacco products and tobacco smoke.

U našim bezdimnim proizvodima koji sadrže duvan možemo precizno da kontrolišemo temperaturu. Time obezbeđujemo da duvan ne dostigne temperaturu koja je neophodna za sagorevanje. Izbegavanjem sagorevanja, smanjujemo ili eliminišemo stvaranje HPHC sastojaka. Ipak je neophodno zagrejati duvan da bi se iz njega oslobodili nikotin i arome.
