I suspect it’s what he’s vaping that is the problem.
When I was vaping an herb to help me get to sleep I would take one single 3 or 4 second draw. That’s it. Hard for me to believe that serious health consequences would come out of that.
That’s my thought. It’s not so much that he was inhaling gas - it’s what we do - but WHAT he inhaled.
When it was still “Corona,” it was noted that propylene glycol prevents viruses from entering through the lungs and is what’s used in fog machines and vapes. There were jokes about buying enough fog machines. Then they discovered nicotine combats Covid. The third ingredient is glycerin. I started vaping immediately because I already knew nicotine was good for stabilizing neurons and helped when I was a teen/ young adult. I haven’t gotten Covid, as far as I know, and it’s helped with the stress of this mess. I also bought Ivermectin around the same time. I thank God I worked in a research hospital years ago and was already anti-vax then.
