You have to also understand this is the internet, people aren't going to always react to something as they would if it was directly related to them, or if you actually were to tell that person what you were saying in person.
So many people have the "haha, sux2bhim" approach just because it has nothing to do with them, but if you were to talk to that person in person their reaction would probably be a lot more humane.
As far as doing drugs is concerned I always do mine with this in mind. "Proceed at your own risk".
