At least one of his friends peddled hard drugs, but I don't know where the drugs came from. And it seemed to be more than mere curiosity. I could sense their desire for that lifestyle, and they were clearly getting social cues from those videos. The way they used words, they way they dressed, etc.
To my knowledge, it was fortunately "just a phase" and they're now more or less normal, functioning suburbanites with mediocre desk jobs.
