The Portland State study fits right into this dynamic. It is, on the one hand, factually true that vaping at an extremely high voltage will cause formaldehyde-releasing agents to develop.
But this conclusion is highly misleading. People dont vape at a high voltage because it causes a horrible taste a burning taste that occurs from overheating the liquid, wrote Konstantinos Farsalinos, a Greek scientist and vaping expert, in an email to me. Farsalinos has done human studies of vaping and discovered that above a certain voltage lower than the high voltage test on the Portland State study people simply couldnt inhale; the taste was unbearable.
