The study examined 20 brands of electronic cigarettes, and analyzed the contents of their cartridges for nicotine, propylene glycol, glycerin, polycyclic aromatic hydrocarbons, and tobacco-specific nitrosamines.
The results were reported in the study abstract as follows: "Varying nicotine amounts were found in ENDS cartridges which were labelled with the same concentration. Chemicals such as PPG and glycerol were found to be present in the nicotine-containing liquid of the cartridges. ENDS varied in their contents and packaging information. Limited information was available on the contents of nicotine and other chemicals present in a variety of ENDS sampled."
The paper concludes as follows:
"While the current attention on traditional tobacco products is important, it is also necessary to focus on novelty products like ENDS, which may encourage maintenance of tobacco usage behaviour and slow down the impact of national smoking control programmes. Tobacco control policy makers and professionals are seriously urged to find ways to address the gap in the scientific understanding and the legal framework of such products, as this gap may impede efforts at curbing tobacco use."

This is because the discussion has very little relevance to the actual findings in the paper....READ MORE >>
