In January 2015 a report found that a third generation e-cigarette — an e-cigarette with variable power settings — set to the maximum power and long puff duration generated levels of formaldehyde that, if inhaled in this way throughout the day, would several times exceed formaldehyde levels that smokers get from cigarettes. A new study took a closer look at those findings in the context of real-world conditions. It concluded that 3rd generation e-cigarettes can indeed produce high levels of aldehydes — but only under extreme conditions which human smokers can be expected to avoid because of the immediate unpleasant sensory effects.
