As the world waits for more scientific information about the long-term effects of electronic cigarettes, new findings show that vapers should be cautious about the voltage of their devices as they vape. This is because a group of researchers discovered that vaping at high voltages resulted in the production of formaldehyde due to the heating of the PG in the e-juice. Users should therefore be cautious about ramping up the voltage to the limits of their devices. The research has attracted debate regarding the practicality of vaping at the voltage levels used in the study since such high levels can make vaping unpleasant. Don’t wait for the scientific community to reach a consensus on the matter. After all, there is agreement that vaping isn’t entirely risk-free, so keep your voltage as low as possible in order to reduce that potential risk to a lower degree.
