For me, it was a chance for me to ask a bunch of questions of people about things I was curious about but were probably none of my business or impolite to talk about, so I suspect to some degree I was guilty of the latter one.
I will say that it was incredibly enjoyable when I took it with the people I was with, which were in mostly safe and contained environments. If the draw to both immediately do more and to seek it out weeks and months later to repeat the experience wasn't so strong, I would recommend it to everyone to try at least once. As it is, I would be cautious if trying for the first time and space out usage if you tend to overindulge and/or aren't one to naturally self-regulate.
Sounds like you were just associating with pricks and those pricks happened to use a popular drug.
They all make the same speech but Somehow they never seem to know about it when 7 people in the class got a copy of test in advance and prepared answers. For every student who's bad a cheating and got caught, there is >15 that the teacher never knew about.
That said, I did coke once(well, twice, but I'm pretty sure the second time was foot powder). It was absolutely serene. I felt crystal clear, dialed in, and perfectly zen. I didn't have a desire to talk, but to just observe. I felt like I had the hearing of a cat. Then again, I probably have unmedicated ADHD. No commercial stimulants have ever made me feel like that though.
I guarantee you these "I tried it a few times and can't stop thinking about it" stories are complete BS.
The effects are very short lived and the more you take the more edgy, nervous and wired you get. It becomes really hard to enjoy.
I guesstimate that 80% of all coke is consumed by completely "normal" people after a few drinks in a bar on the weekends, and that's that. No craving, character changes and all that stuff.
For weeks after, she would crave and daydream about cocaine. The fact that, despite being able to quit, she missed it that much made me decide to never ever try it. I know people get addicted to games or gambling or whatever else, but it seemed pretty bad.
