Note that the black vape on the right in the photo is very much unlike the other two.

It’s a dry herb cannabis vaporizer —- oddly, one of the very few that’s a certified medical device. (it’s a storz and bickel crafty)

There’s a vast difference between concentrate/ejuice/distillate vapes and something like a crafty.

It would be nice if the two categories of vapes could be separated more cleanly when discussing health effects because it would separate a lot of the variables.
