It could, but I've had at least 50-60 trips in the last 20 yrs & I'm stable as a rock. Actually, I think it can help people if you are serious about it & don't just do it at or parties or carelessly like a fool. Most people underestimate the importance of ambient setting when doing psychedelics. If you approach it with GREAT respect it can be a shortcut to achieve bliss & enlightenment. Just keep it to once or twice a year. Also, KNOWING exactly what & how much you are doing is equally important. I'll only do 100% pure, or quality mushrooms. Stay away from DMT unless you are ready to meet god. When was high school though? And how many micrograms was the dosage?
Also, if you do it & you don't like it, STOP DOING IT!! Given the nature of the drug, you can't fight it too much or else you are scarred.
