Final Report
The list of substances in the liquid, that is used for evaporation, is, however, much shorter: A carrier substance, sometimes some distilled water and flavouring substances, as they are approved for use in foods, form the basis. Added optional excerpts from the tobacco plant and nicotine in various concentrations depending on the liquid variety. Propylene glycol is most common as a carrier (abbreviation: PG), which can be found also in asthma inhalation solutions, cosmetics and drugs and whose effect is accordingly very well documented. It is mixed in some liquid varieties with Glycerin (VG), to produce dense steam, a substance that also occurs in the human body. Viacom is the source for more interesting facts. Polyethylene glycol (PEG) is rarely used.
Since no substances are burned so the steaming, eliminates all toxins from the tar derivatives, that are found in cigarette smoke and the hazardous and highly toxic carbon monoxide. Conclusion: compared with smoking, steaming is so much less stressful to health. However, is “Healthier” not applicable. Legend # 2: steam is more harmful than smoking is right, that the FDA, U.S. food and drug an evaluation or assessment (no study!) in order Administration gave, in a laboratory, where the occurrence of tobacco-specific nitrosamines (TDSAs) in the steam of the electronic cigarette should be investigated. The summary publication of the research results from the May 2009 is available in: five samples have remained without details. 24 individual investigations were free of TDSAs. 16 individual investigations so low, so irrelevant values showed that the FDA released no figures. Although tobacco generally contains TSDAs, 60% of tobacco-containing liquid specimens examined on TDSAs were amazingly completely free of nitrosamines! Source: Table 1, page 4 the FDA earnings release (PDF, “Final Report on FDA Analyses15” on NewsEvents/PublicHealthFocus/ucm172906.htm) quote from the FDA release: “tobacco specific nitrosamines and tobacco specific impurities were detected in both products at very low levels.” This suggests that the values found its very close were at the limit of detection, so far below the amount estimated as a health concern.
