I think many pro-psychedelic and pro-drug people in general underestimate how much these drugs vary with people. I have a friend who will make a gram of weed into cannabutter and eat the whole thing in 1 sitting, getting about 200mg of THC at once, and not have any major problems. He was a big proponent of "there's no such thing as too much" until he saw another friend of ours have an incredibly intense panic attack on 10mg of THC. My wife has intense anxiety on as little as 2.5mg of THC, regardless of CBD and CBG levels (whether via gummies or straight plant matter); no dose can be thereputic for her.
Based on the number of people I know who have experimented with these drugs, I think there's a smokescreen effect where people who have bad experiences don't talk about it nearly as much as people who have good experiences, so it seems significantly less risky than it is. Of the 10 or so people I know personally who had a psychedelic experience, about a third of them have had bad ones. They just don't really talk about it and never want to try it again. I wouldn't say that most people should try psychedelics at least once unless I knew what the actual numbers were, otherwise I'm pushing many people into having a horrible nightmare for hours on end.
Maybe I'll go back to normal eventually, or maybe I had a latent anxiety disorder that was triggered by the mushrooms and I'll just never be able to enjoy weed again. I don't know. My friends didn't have experiences as bad as mine, but they did have a bad time. Most of my friends love psychadelics, and I'd never take them away from them, but before we all tried them, they were talking the same way, and it's what made me excited to try them. I wasn't expecting it to do to me what it did.
