That isn't what was killing people. There was the vitamin E issue that caused some lung irritation in some people. The synthetic marijuana is what was killing people. Bad stuff.
I had some lung issues at the time, had a sample taken from my lungs after it cleared up. Reported the Dr. for insurance fraud as he skipped an xray when he found out I was well. Did much research and am convinced the whole thing was vitamin e. The group making them got busted. That not to say the fake shite is healthy just the alarm was caused by vitamin e.
I'm glad because legal status allows me to grow both tomatoes and marijuana at home garden which is neat. The positive side here is that I'm getting skilled at growing plants (I mean indoor tent growing similar to this). I doubt that it would allow me to become self-sustainable farmer but still that's useful especially during quarantine.
