Testing by an independent laboratory found that the amount of fumes inhaled from the Lotus Vaporizer at vaporizing temperature is the same as that inhaled from ambient air at the high end of normal air quality (1 microgram per day). i.e. No fumes are added.
According to the US Government Center for Disease Control (CDC) (section 1.3 paragraph 6), we breathe in between 0.1 and 1 microgram of nickel per day.
