Why do people get addicted to drugs?

Why do people get addicted to drugs? Because it's around them, they associate themselves around people that are bad influence on them, and peer pressure. You can't control anyone and their lives. It's their choice to do the drugs and use it. Basically, I think it is peer pressure that is how I got starting using drugs. Then I quit because I wanted to live longer and saw that they weren't worth doing nothing. It slows down your life and it waists your time.
