That said, despite my fondness for these experiences, I do personally know 2 people who experienced prolonged (1-2 weeks) psychotic episodes after taking LSD. So there is more risk associated than many believe or want to accept. I haven't heard of this happening with mushrooms.
That said, don't accept third hand reports of psychedelic experiences. If you want to read first hand accounts, I recommend browsing the trip reports at https://www.erowid.org/.
Or better yet, just give it a try and see for yourself. :)
I guess I stated it in the way I did because, most enthusiasts start thinking that LSD is "the answer" or "the cure" etc etc.. and get super 'bout it and consequently tend to reject the idea of any real negative consequences, because the experience really is truly amazing and even the day after can be even more amazing, in stark contrast of the 'hangover'.
So I just wanted to mention in spite of this, weird things do happen in very rare cases, and this could even be due to the fact that it's illegal and thus not manufactured with consistent/optimum purity.
Both of my friends were quite experienced with dozens of enjoyable trips under their belt.
Appeals to reason don't force us to bow to economic imperatives. Wanting to preserve nature for the joy it brings us is perfectly rational and reasonable.
