Study: Vapes leach toxic metals

The vape crisis of 2019 likely resulted from vitamin e acetate added to unlicensed cannabis oil. Now a new study found vape users are inhaling toxic substances that derive from their vape hardware.

• Chris Roberts reports in Forbes: “Studies of e-cigarettes and nicotine-vaporizing devices have turned up higher levels of heavy metals in users’ blood than cigarette smokers, but [until now], little research has been conducted to see if the same holds true for cannabis vaporizers.
• The research, expected to be published in the peer-reviewed journal Chemical Research in Toxicology, found “[a]t the high voltage and temperature settings of standard [vaporizer] devices, dissolved metals or even fine metallic particles from the heating coil or the liquid could have the potential to be inhaled into the consumer’s lungs,”
• It continues, “Results indicate that chromium, copper, nickel, as well as smaller amounts of lead, manganese, and tin migrate into the cannabis oil and inhaled vapor phase, resulting in a possible acute intake of an amount of inhaled metals above the regulatory standard of multiple governmental bodies.”

Another study, conducted by a physician and fellow at the libertarian Cato Institute, found REC access to be associated with a 6.29% reduction in suicide rates among men in their 40s, but did not affect other mental health outcomes.
