Interesting article in East Bay Express: Scientists Criticize UC Berkeley's Ban on E-Cigs
"E-cigarettes also contain tiny amounts of formaldehyde — which the US Environmental Protection Agency considers to be a "probable human carcinogen" because frequent and intense exposure to formaldehyde has been linked to certain cancers."
Where does the formaldehyde come in? The flavorings? The silica wick?
It seems most of the studies are testing the cigalikes that have pre-filled cartomizers. I think the polyfill-like materials used as wicking may contribute to the formaldehyde. But who knows

Makes sanse, but I've never heard about it before either.

If I remember correctly, those studies were debunked for:"E-cigarettes also contain tiny amounts of formaldehyde — which the US Environmental Protection Agency considers to be a "probable human carcinogen" because frequent and intense exposure to formaldehyde has been linked to certain cancers."

What many people may not know is that our own bodies produce and use formaldehyde as a part of our normal metabolism (Final Report on Carcinogens Background Document for Formaldehyde [PDF], 2010). When we are exposed to methanol (e.g., via inhalation or ingestion of foods like citric fruits and juices, vegetables or fermented beverages), our bodies break it down into formaldehyde and other byproducts. Our bodies produce formaldehyde as a result of DNA demethylation (an important process for controlling gene expression, e.g., in developing embryos) and other biological processes. It is such a regular part of human metabolism, that our normal, naturally produced blood concentrations are generally about 2-3μg of formaldehyde per gram of blood (or about 2.12-3.18μg/mL)*. And it is actually a pretty important chemical; our bodies use formaldehyde to form DNA and amino acids (Toxicological Profile for Formaldehyde [PDF], ATSDR, 1999).
