Reference

The consumption of tobacco remains the main cause of cancer of the mouth but it a type of consumption that evolves rapidly due to the increasing use of new products and the combination of these with traditional products: cigarettes cigars and pipe tobacco, among others. [19659019] study presenting at the General Session of the International Association of Dental Research, a team of experts led by Benjamin Chaffee and Neal Benowitz, of the University of California, San Francisco, evaluates the exposure to carcinogens ] according to the use of different types of products related to tobacco .

Volunteers provided urine samples for the badysis of tobacco-specific nitrosamines (TSNA) c in the form of nitrosonornicotine (NNN, a known oral and esophageal carcinogen), pyridyl-1-butanone (NNAL), a metabolite lung cancer and also the total equivalents of nicotine .

Participants were categorized by the type of product they consumed. One category included cigarettes, cigars, water pipes, pipes, cigars. The latter were smoke-free: powdered tobacco, chewing tobacco and electronic cigarettes and products of replacement of nicotine .

All categories were found to be high concentrations of nicotine and TSNA compared to non-users. Exposures to TSNA were highest among smokeless tobacco users, whether used alone or in combination with other types of products. Exclusive users of electronic cigarettes were exposed to lower levels of NNN and NNAL than users of other products, despite exposure comparable to that of nicotine . However, most users of electronic cigarettes used normal tobacco at the same time, which caused exposure to TSNA similar to smokers of ] cigarettes exclusive.

The badysis shows that the vast majority of tobacco smokeless products who do not use cigarettes are exposed at comparable levels of carcinogens or higher than those who smoke only tobacco, levels which, according to the authors, put them at considerable risk .
