A study commissioned by the Japanese Health Ministry claims that e-cig liquid, which is vaporized and inhaled, contains as much as 10 times the amount of cancer-causing substances.
The study claims to have found chemicals like formaldehyde and acetaldehyde in various forms of e-liquid.
Although this study doesn’t bode well for the alternative smoking devices, other studies have shown positive effects, which goes to prove the point that more study is needed.
Thomas J. Glynn of the American Cancer Society discusses this recent study, and the ongoing debate over e-cigs, in this interview with WBUR in Boston.
