I am suspicious that smoking pot is just as bad for your lungs as smoking tobacco and we simply don't have decades of evidence yet. It stands to reason that inhaling burnt organics is going to have many of the same effects regardless of which plant is involved.
That's likely true, although with legalization has come the popularity of - and even preference to - vape pens and edibles, which weren't as accessible.
make it classy (esp stuff like vape pens
I don't know. It feels like vape pens is one of the least classy things going on at the moment. I think the only thing that can make "weed" acceptable and "classy" is some variation on fancy edibles (or perhaps drinkables to bring the discussion full circle)
Coming soon to a state near you.
