In a discussion about this on the radio (for what it’s worth) a caller from Wisconsin claimed that almost all of the lung problem cases there have been caused by vaping illegal THC cartridges. The THC and vitamin E are interacting somehow to cause the problem. And just this morning I heard on the news that a big THC operation was busted in Wisconsin. They were making 5000 cartridges per day. Maybe something to keep in mind.
Vaping for me is neither here nor there. I understand it has been useful to help people quit smoking. Having said that, I don’t understand why non-smokers would take it up. For kids, I guess there’s something cool about it, just as with cigarettes.
Vitamin E is an oil, directly inhaling vaporized oil does damage to your lungs.
