My grandparents and my uncle smoke marijuana for medicinal reasons.
I picked up a container that had been left on the couch and my hand became incredibly itchy and had hives that didn't go down for a couple days.
ever since I've avoided it.
I've also always found the smell unpleasant so that experience really didn't help anything.
Not something I've ever taken myself. Partly because it's not legal here yet - but even if it was, I don't think I would. It's simply never appealed to me.
