I haven't read the paper, but the article calls out smoking specifically and it's bad effects.<p>To be fair: Inhaling "smoke", aka combustion byproducts, of literally _anything_ is _definitely_ not good for you. I'm surprised when states began to legalize they even allowed for smoking it.<p>It also somehow lumps vaping in there, but vaping definitely does not produce tar and the other bad substances that combustion does... so I do need to go read the whole thing at some point.
