Some more info..
A cartridge or tank contains a liquid of propylene glycol, glycerol, or both, as well as nicotine and flavoring. These chemicals are heated to the boiling point with a battery-operated atomizer, creating a smokeless vapor that is inhaled.
But formaldehyde-containing chemical compounds can be released during the "vaping" process as the liquid is heated. Pankow said some e-cigarettes can burn hotter than 1,000 degrees fahrenheit.
"The difference in e-cigarettes is the material that is heated and turns into hot gas as it cools is not tobacco, but two main chemicals," he said. "When it gets really hot, unwanted reactions occur."
Pankow said the same risks likely do not occur when vaping dry marijuana or hash oil, which typically does not use those chemicals. "But it's totally likely that some people dilute hash oil with propylene glycol and glycerol, which we know can form formaldehyde," he said.
I don't vape anything in my e-cig but 100% PG, there is no Glycerol mixture here.. So if its the mixing of the 2 then BURNING and not VAPORIZING then yes i can see an issue..
This study is fucking flawed to shit and back.
See at the very end they state its 2 chemcials causing a reaction.. Not 1 ... PG and VG are the 2 commons found in e-cigs.. I don't know where the fuck they got Glycerol from but prolly ordered some china made shit juice..
Know your suppliers know your juice's demand COA's and analytical testing reports on a regular basis on any juices you buy!
Or just make your own buy straight up PG and mix your own flavorings. ( there just esters and alcohols )
