Guided psychedelic experiences are largely beneficial. Unstructured psychedelic experiences can be a bit more...variable depending on the circumstances; there's a lot more chance for shit to go south.
I don't think they should just be legal to buy at a corner store or whatever. But they should be available to people who need them.
Also psychedelics aren't physically or psychologically addictive. If anything it's the opposite. Very few people are craving another trip the day after a heavy dose. (Of course there are exceptions to everything).
