A British study conducted in real conditions over the long term has just proven that saboteurs are less exposed to harmful substances than smokers.
This is the first comparative study of the long-term effects on the body of normal cigarettes and electronic cigarettes. Researchers from the Department of Epidemiology and Public Health at University College London have just published their findings in the journal Annals of Internal Medicine.
Scientists conducted research on 181 people in 5 groups: conventional cigarette smokers, former smokers who became vapotors, former smokers using nicotine substitutes, smokers who also use electronic cigarettes, smokers who also use substitutes Nicotinic acids. They then performed urine and saliva samples to assay several biomarkers: nicotine, tobacco-specific nitrosamines, and volatile organic compounds.
Their first conclusion is that the level of nicotine varies little among participants, irrespective of the method of delivery. On the other hand, a major difference was observed in the levels of nitrosamines specific to tobacco, which are carcinogenic compounds involved in the occurrence of lung cancers. People who smoke only electronic cigarettes or use only nicotine substitutes have much lower rates than the conventional cigarette smokers or users of both types of cigarettes.
These findings provide an additional argument for those who argue that e-cigarette use is important in smoking cessation. It remains to be pointed out, however, the safest means of avoiding exposure to carcinogenic compounds remains the absence of consumption, both of conventional cigarettes and of electronic cigarettes.
