Researchers and a vaping advocacy group had mixed opinions on the study. The American Vaping Association and e-cigarette advocate researcher Dr. Michael Siegel of Boston University criticized it by email for using unrealistic conditions and overestimating potential harm.
In particular, they said battery voltages were tested up to a level that would have produced an unpleasant taste called “dry puff” that vapers avoid.
“This is a faulty study performed by researchers with limited to no understanding of how vapor products actually work,” said Gregory Conley, president of the American Vaping Association. “The conclusions of respected organizations like the Royal College of Physicians and Public Health England — that vaping is at least 95 percent less hazardous than smoking — remain in force.”
