Load of fucking biggots on here today. So the kid was influenced to cry crack once by some other idiot and now he is a druggy? BTW, you freebase crack, you can't smoke it.
Far as I can see he was lucky. Almost 2 decades ago I had a run in with the crack deamon after someone I trusted convinced me its not so bad. Spent half my salary that night... and it was hell for the next few months until I went cold turkey to this day. Asshole who got me into it, lost his wife, job, new house and two kids....
So, the kid made a mistake, be glad he came out ok, and rather than push him out (probably back to the asshole who gave him crack), try and pull him in, show him what's what in a subtle way that is more lifechangeing than bitching someone over small shit.
