I'm not going to argue that some people are not helped and I think there is a lot of interesting research.
But there seems to be a lot of people who think there must be some deeper meaning when you use psychedelics so they sit down and try and think about negative things to work them through, get stressed out and starting to spiral in a negative thought loop that is not really based in reality (like "my friends do not really like me, I suck").
Then they have a horrible trip and really did not learn from it because, your brain is often pretty stupid on psychedelics, but frame it as a positive experience on forums. It would be like people not handling alcohol saying "Yeah, sure I really went crazy and fought my dad, destroyed my car and ended up crying in a bush, but I really learned something about myself". No, the drugs made your brain think in a shitty way.
Maybe I'm just cynical but I'd say don't try to get deep with psychedelics until you are really used to them. Have fun and do the "abusing party drugs" part or watch a funny movie instead.
