Coke's reputation is WAY worse than what it deserves.

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.
