Actually...weirdly enough, a majority of these cases of lung damage from vaping happened in 2019-2020. One of the most likely culprits of the outbreak is a chemical called vitamin E acetate, which was used as a thickening agent in weed vapes. I don't think we've had many cases since the major outbreak.

So it might not have been "vaping too much" so much as it was likely contaminated vapes.

I don't vape, myself. But there is always more background info to discover on these things.
