These are really the worst things that can happen to kids. Think about yourself and your friends. You care about each other. You are there for each other. You are all trying to break through the barriers that say you are a kid and not old enough to know anything or be able to do something.
Drugs are never a solution.
They only add to the confusion. Maybe you feel or suspect your friend is using crack. There are signs you can look for. It's hard to tell your parents about a drug problem or for one kid to tell about another kid's drug problem. Stealing cannot be reversed.
