A study conducted by Italian researchers and published on Elsevier, compared the chemicals passed into the human body via e-cigarettes and regular cigarettes, by testing participants’ urine samples.
The study titled, “Urinary biomonitoring of subjects with different smoking habits. Part I: Profiling mercapturic acids.”, analysed urine samples of sixty-seven healthy adults with different “smoking” behaviours: 38 were non-smokers (NS), 7 were vapers and 22 smoked traditional cigarettes.
While it is common knowledge that regular cigarettes contain thousands of chemicals, many of which are carcinogenic to humans, it is widely believed that the content of vape products is less known. To this effect, the researchers aimed to determine and compare the exposure associated with the different products, by profiling urinary mercapturic acids as biomarkers of toxic compounds.
In line with countless previous studies, the compiled data confirmed that regular cigarettes are a major source of carcinogenic chemicals such as benzene and 1,3-butadiene. In comparison, e-cigarettes are a minor source and mostly associated with exposure to chemicals with less carcinogenic potential, such as acrylonitrile and acrolein.
Vapers are inhaling less carcinogens than smokers
A similar 2018 study also based on urine samples, had indicated that vapers are inhaling more heavy metals and carcinogens than non-vapers, but less than smokers.
The study titled Comparison of Nicotine and Toxicant Exposure in Users of Electronic Cigarettes and Combustible Cigarettes, was published in the journal JAMA Network Open. The researchers had analyzed urine samples of 5105 participants, and compared samples of smokers, vapers, dual users and non-users.
Naturally, the participants who neither smoked nor vaped showed the lowest levels of toxic chemicals in their pee, “Compared with exclusive e-cigarette users, never users had 19% to 81% significantly lower concentrations of biomarkers of exposure to nicotine, TSNAs, some metals (eg, cadmium and lead), and some VOCs (including acrylonitrile).”
Exclusive vapers showed lower levels than smokers. “Exclusive e-cigarette users showed 10% to 98% significantly lower concentrations of biomarkers of exposure, including TSNAs, PAHs, most VOCs, and nicotine, compared with exclusive cigarette smokers; concentrations were comparable for metals and 3 VOCs.”
Vapesourcing Opinion:
Vapers are inhaling less carcinogens than smokers,which has been repeatedly proven. We must believe in scientific research and don’t listen to misleading statements that have no experimental basis.
