With psychedelics the risk profile is very different. Firstly, people can do harmful things during the trip. Second, a more vague, difficult to measure and predict concern around long term psychological effects to some people.
Right, my pronoun is dangling here. "It" was meant to refer to the status quo of making them inaccessible without a lot of difficulty and breaking the law.
I haven't personally seen it either, though sounds like I'm less experienced than you.
I've heard of a few though. In 2019 a bay area software engineer who by all accounts was a good guy, maybe somebody here knows him, attacked some people on a trip. He also stole some vehicles, drove over some people, and was shot by law enforcement trying to stop him. He was paralyzed.
That's an extreme oddball case or freak accident.
I think one needs to take in such a story and not sensationalize it or overstate danger, or get yourself scared, but also, you do need to know that things can go out of control for some people.
