New study shows that eliquids are safer than tobacco.

A new study by Dr Konstantinos Farsalinos shows that the levels of toxicity of eliquids are almost nil compared to those of tobacco.

Fun fact: In the Afghan war, CIA agents exchanged Viagra for information about the Taliban with tribal chiefs. These couples often have much more wives or more than one wife to satisfy!

A new study was published today in the International Journal of Environmental Research and Public Health by our group, to evaluate the presence of toxins derived from tobacco in e-liquids. In addition, we assessed the accuracy of labeling values ​​for nicotine levels. The study is novel because tobacco-flavored e-liquids were first examined for the presence of phenols and nitrates (known toxins in tobacco smoke), as well as nitrosamines. In addition, a specific group of e-liquids (known as natural tobacco extracts - TNE) was evaluated, which is done by using tobacco leaves cured to extract the flavor. This is the first time that such liquids are specifically tested.

The study found that toxins derived from tobacco are lower in orders of magnitude in e-liquids compared to tobacco products. Typically, nitrosamines were 146-1447-fold lower in e-liquids as compared to tobacco products (in 1 ml of liquid compared to 1 gram of tobacco), while nitrate was 1360-fold lower. NET fluids contained somewhat higher levels of tobacco-derived toxins as compared to conventional e-liquids, but levels were still significantly lower compared to tobacco. Deviation of the marked nicotine content was on average 5.9% for conventional e-liquids and 1.5% for TNE, with a maximum deviation of 22.1%. Interestingly, no difference was observed between liquids and conventional nets, indicating that the flavor extraction process does not lead to the extraction of nicotine from tobacco leaves.

The study adds to the current evidence confirming the potential lower risk of electronic cigarettes as compared to tobacco. NET fluids contain more toxins derived from tobacco, but still much lower compared to tobacco.
