Researchers warned that the level of chemicals used for flavored e-cigarettes could have been harmful and lead to respiratory problems.
The chemicals used to add an array of tastes to e-cigarettes – ranging from coffee to bubble gum – are often the same as those used in food and confectionery, and are therefore marketed as safe by manufacturers.
Oregon researchers at Portland State University, claimed, that this safety corresponds to eating, nevertheless not inhalation.
The team is examining 30 different products and set out to determine the type and level of chemicals used in both disposable and refill bottles.
Aldehydes are recognized to be primary respiratory irritants and there were six out of 24 compounds identified.
Vapors are exposed as twice as the recommended limit of Benz aldehyde and vanillin, if consumed at a rate of about 5ml per day, a usually used volume.
Added by the researchers, “toxic abjection products may be produced by the reaction of the flavor chemicals at the high temperatures present during vaping.
Speaking in the journal Tobacco Control, which promulgated the report, researchers admitted their sample “plays a fraction of the e-cigarette products on the market”, but added: “The results obtained are likely to be the same to what a broad survey would have exposed, and in any instance, propose that very high levels of some flavor chemicals are undoubtedly present in a great number of the thousands of products currently available.”
Although is known little the possible long-term health consequences of vaping, however e-cigarette market is rapidly expanding , both in the UK and the US.
“Regulations are needed,” researchers added. “These should include a compulsory element listing, limiting the levels of sure flavorings, and limiting total permissible levels of flavorings, particularly as there is some pertain that flavored products might make e-cigarettes more attractive to young people.”
