crack cocaine

I saw my seven year old cousin trying to put a needle to his arm, what the world is coming to? I am sure he didnt see me doing that so i asked him what is he doing. He says he saw a man on tv doing it and he would try it. I have to thoroughly explain to my cousin all about crack cocaine or rocks if you call it. That goes to show you crack cocaine is used worldwide and it is more famous than cartoons. I still dont know the reason for people consuming this substance but i dont want to find out. Crack cocaine is very very dangerous....
