Oh yea- if you're experimenting, sure. A couple of acid/shrooms trips in high school or college generally won't have lasting ramifications. However, your point about "doing too much too young" is accurate.
I had a neighbor in my mid-twenties who did too many shrooms too often from a young age, and at 23 years old he believed that his half-Cherokee grandfather had been a werewolf who didn't die, he just didn't transform back into human form, and that his whole family line possessed the "wolf spirit." You used to see him light a fire in the backyard in the middle of the night (in the city of Atlanta, btw) and literally howl at the moon- his roommate ended up having to kick him out, lmao.
Keep in mind, he was a white kid who did have Native American ancestry up the line, but he was raised in the fucking suburbs and just happened to get caught up with delinquents/ started using shrooms regularly in high school. Eighty percent of the time he'd seem totally normal, act normal, and then something would trigger that pathway in his brain, and he'd start going on about transforming into a wolf and "family secrets" and then walk off down the street barefoot- total delusion right under the surface.
I'm not well versed in how often Styx used acid/shrooms or how early, but it could definitely exacerbate any high-functioning meltdown/ obsessions to the point where it becomes full on delusion.
