Why do people do drugs?!?

I get soooo POed at these idiots who do drugs. It's pointless, and it ruins your life. I really wanna know why these hobos do drugs! Yeah, it gets you high, or gives you a buzz, or wutever! Than they say it's becuz of someone else making them do it. If they had something called... hmm... WILL POWER, than maybe they wouldn't be stealing money from other people, and ruining their entire life! I hate it! WHY DO THESE PEOPLE DO THIS! WHAT GOES THROUGH THIER MIND!?
