January 23, 2015 Pam. Medscape news:
Researchers have found excessive levels of formaldehyde, an established carcinogen, in the vapor produced by e-cigarettes when the devices are used at high voltage. The cancer risk from this unexpected finding is much greater than from conventional cigarettes.
This finding was reported in a research letter published onlineJanuary 22 in the New England Journal of Medicine.
But detractors — and there are a number — are calling the study “irresponsible” because the conditions under which these researchers analyzed e-cigarette aerosol in no way resemble the way the so-called “vapers” actually use e-cigarettes.
