Carbonyl Compounds Generated from Electronic Cigarettes

This Japanese study triggered titles such as « e-cigarettes up to ten times more carcinogens than conventional tobacco cigarette ».

Of course, the study does NOT say this at all. This is FUD at its extreme limits.  Here is the study, with the article published by Dr Farsalinos about it, and an article from Slate France denouncing the scaremongering.

Cette étude japonaise a déclenché un barrage de gros titres dans la presse, comme « la cigarette électronique dix fois plus dangereuse que le tabac ».

Il n’en est bien entendu rien. Le Dr Farsalinos, la FIVAPE ont répondu, et Slate France a même publié un article dénonçant le mensonge commis par l’AFP.

Summary

Electronic cigarettes (e-cigarettes) are advertised as being safer than tobacco cigarettes products as the chemical compounds inhaled from e-cigarettes are believed to be fewer and less toxic than those from tobacco cigarettes. Therefore, continuous careful monitoring and risk management of e-cigarettes should be implemented, with the aim of protecting and promoting public health worldwide. Moreover, basic scientific data are required for the regulation of e-cigarette. To date, there have been reports of many hazardous chemical compounds generated from e-cigarettes, particularly carbonyl compounds such as formaldehyde, acetaldehyde, acrolein, and glyoxal, which are often found in e-cigarette aerosols. These carbonyl compounds are incidentally generated by the oxidation of e-liquid (liquid in e-cigarette; glycerol and glycols) when the liquid comes in contact with the heated nichrome wire. The compositions and concentrations of these compounds vary depending on the type of e-liquid and the battery voltage. In some cases, extremely high concentrations of these carbonyl compounds are generated, and may contribute to various health effects. Suppliers, risk management organizations, and users of e-cigarettes should be aware of this phenomenon.

 


Conclusion

Studies have shown that e-cigarettes emit toxic carbonyl compounds, generated from thermal decomposition. These substances can have adverse health effects; however, in most cases, the levels are lower than those in tobacco cigarette smoke. It is important to expand the research in this field, to better understand the source of carbonyls emitted from e-cigarettes and find ways to reduce them.
