There is a lot of high minded bullshit in this thread. Since we in the ski community are generally a bunch of over privileged, sheltered white kids, I suggest taking a step back and looking at the realities of addiction before being so goddamn judgmental, because your self righteous proclamations are a load of uninformed twaddle.
Most people don't just decide to try some heroine. Most people that end up on the stuff start with pills, and anyone here who has had some gnarly fall skiing and gone through subsequent surgery and rehab can understand how easy that shit is to get addicted to. Your heroes Tanner and Dumont have both had pain pill problems. Once you are hooked on the pain pills, withdrawal from a heavy addiction is worse than any of you little 15 year old preachy shits can understand. So it is pretty easy to see how, once the money runs out, people switch from the expensive pharmaceutical heroine (mainly oxy and hydrocodone) to the cheaper stuff that is more potent (heroine).
There is never a point in this scenario where kids just decide that mario kart is getting boring, so maybe they'll shoot a little bit of heroine. It is an unfortunate process in which people turn to the drugs out of intense desperation that most of you cannot understand.
Obviously some people do just try heroine, but even then these people aren't necessarily morons either. Most that try the hard drugs are aware of the risks but have major fucking problems and are looking to just get some respite from their life. The skinny white chick that attempts suicide as a cry for help does it for the same reasons as many people try drugs like heroine, but she gets all the help and support in the world while the drug users are demonized as a sub-class of humans and thrown in jail.
