Components found in cannabis vaporizer hardware appear in the aerosols that users end up breathing, a new study found.
But the oil isn’t what end users are consuming—they breathe in a mixture of aerosols that can include elements of the vaporizer device itself, which can include of heavy metals including chromium and nickel.higher levels of heavy metals in users’ blood than cigarette smokers, but so far, little research has been conducted to see if the same holds true for cannabis vaporizers.
Researchers plugged the pens into a power source connected to a wall socket and used a “smoking machine” to mimic a human’s breathing action and draw out the resulting aerosols. A total of “50 puffs” worth of aerosol were drawn from each cartridge, and the aerosols were then analyzed using a plasma mass spectrometer.
That means that the still potentially harmful aerosol would pass all legal cannabis states’ testing regulations—which in turn means that states’ safety standards need to be re-assessed, the authors concluded.
