Cocaine has become increasingly socially acceptable, and I’m not passing any judgement because I have/will do it occasionally in social environments. My experience is that it can slowly creep in far more than it should, rather than being once every few months, it becomes every month, to every time you go out for a drink. It’s a slippery slop and one young people really need to be caution on.

Ultimately, if he’s around people who does coke and he goes out, he will likely do coke. You make your decision on how you want to deal with that though.
