E-cigarette warning refuted
Glycol in e-cigarettes turns to formaldehyde – but only at very high temperatures.
A new study, published in the New England Medical Journal, aimed to show that formaldehyde formed by vaporised glycol could turn e-cigarettes into cancer-causing objects.
But the study was refuted by Professor Michael Siegal of the Boston University School of Public Health.
Siegal found that the temperatures at which glycol was tested when it disintegrated into formaldehyde were much higher than could be reached by e-cigarettes.
