As I tried cocaine only once or twice (I hated the fast heart beat as a side effect), I can more talk about what I felt and try to project on a long horizon: I felt like I know a lot of things, the solutions to all the hardest problems in my life.

I wrote it down, and next day when it wore off, I saw how stupid I was, but I see this effect in my ex friend. He used his social skills to get money from everybody and didn't care about lying to everybody. He got super confident in everything even if his shy antisocial friends knew much more about those topics.]

He was quite damaging to a lot of people who trusted him from before when he wasn't an asshole, and he's still in the process of finding new victims as he went into huge debt and played away all the money his mother gathered through hard work all her life. He is her only child, and his dad died in a car accident when he was in his teens.
