About 5 years ago my friend tried acid for the first time and enjoyed the "profound insights" a little too much. I know this isn't common but he ended up getting addicted to acid, and proceeded to go on a 10 day long acid fueled frenzy. At the peak of his trip he believed that he was Jesus and that he was here to save mankind. Being the good modern Jesus he thought was, he proceeded to spread his Gospel by trying to friend EVERY SINGLE PERSON ON FACEBOOK. He at one point even posted his credentials online so that anyone and everyone could use his account to add more friends. His behavior was absolutely insane but the acid made him feel like it was "profound".
The point I'm trying to make is that while psychedelics can make you feel extraordinary feelings, there's no evidence that the insights gained from tripping have any use in reality.
