Electronic cigarettes are often market as a sizable option to regular cigarettes , but that does n’t mean they ’re good for you . In fact , The Vergereports , researchers at the Lawrence Berkeley National Laboratory recently name 31 harmful chemical in Es - cigarette vapour , including two probable carcinogen , or cancer - cause substances .
In astudypublished inEnvironmental Science & Technology , investigator explain that the thermal decomposition reaction of propylene diol and glycerin , two of the principal solvents find oneself in e - cigarette liquids , produces a vast range of toxic chemicals . These admit propene oxide and glycol , which researchers conceive are carcinogenic .
researcher also found that degree of chemical substance emission were subordinate on heating plant , the type of e - coffin nail used , and the years of the equipment . In universal , as e - cigarettes grow quick , they let go more chemicals . That mean the first few puffs of an e - cigarette as the gadget heats up broadly speaking take fewer chemicals than subsequent puff . Additionally , research worker discover that e - cigarettes with just one heating whorl emitted more chemical substance than those with two , and that as devices aged , buildup of residues on the whorl also caused an gain in chemical emissions .
While the level of chemicals emitted in e - cigarette vaporization were lower than those let out by fag , researchers say that does n’t make them secure . For instance , while unconstipated cigarettes emit between 400 and 650 micrograms per fag of acrolein ( an eye and lung irritant ) , e - cigarettes emit closer to 90 or 100 micrograms in the 20 puffs ( roughly the equivalent of a traditional butt ) . While that ’s substantially less acrolein per pouf , it ’s still enough to appall scientists .
“ exponent of e - cigarettes say emanation are much low than from ceremonious cigarettes , so you ’re better off using e - cigarettes , ” researcher Hugo Destaillats explained in astatement . “ I would say , that may be straight for certain user — for example , long - time smokers that can not quit — but the problem is , it does n’t imply that they ’re salubrious . steady cigaret are super unhealthy . E - cigaret are just unhealthy . ”
