Why don't people wake up?

Today in one of my psychology classes we were talking about the effects of drugs on our mental state. My professor mentioned a case with one of her best friend's sons; he died a few years back from an accidental overdose. She was quite cynical of this terminology "accidental" overdose. Do people not understand that there is the possibility of dying when doing something as stupid as drugs?

I really wish people, especially high school and college students would open their freaking eyes and realize that it COULD BE THEM! Why is that so hard to believe? Why do young adults make it so hard to believe that something really could go wrong? It would be really helpful to everyone (not just the young adult) if they would grasp the idea of life and how fragile it is. That way, we as friends and family members won't have to mourn another "accidental overdose" death. It is just too sad to see lives wasted that way.

((I don't mean to offend anyone by these statements. I just really don't want to hear about another SMU student or someone I know personally die from something that is SOO AVOIDABLE!!!!!!

Dear America,
Please wake up.
Thanks.
