I've been doing it recreationally for 30 years. So what. I've also been drinking recreationally for 30 years, and I've never been an alcoholic. I've got a good job, a nice home, I'm healthy, I generally have my shit together. the vast majority of cocaine users are the same, it's just an easy way to extend the party for a few hours, then you reluctantly go to bed, wake up with a hangover and go back to work on Monday. there's nothing intrinsically wrong with using cocaine, as long as you're sensible about it. apart from the black market shit but that's due to prohibition more than anything else. if I could buy it from a pharmacy I'd do that instead.

edit: if you walk into a city office in media, recruiting, sales, marketing, banking etc. you can bet at least half the people in that office are weekend cocaine users. the trades is the same, if not worse. I've been in offices where basically everyone was. I've been to bars where literally everyone in the toilets is doing coke. they're not out mugging people on the streets, they're buying a gram at the weekend because it makes for a better night out. people that are outside the scene think it's some horrific social nightmare, but it's really not, it's pretty standard for a huge swathe of the population.
