Why do teenagers do so much illegal stuff?

Depends on the teen. Some rebel against their families. Some do it to fit in. Some do it to seem cool, or for a problem they don't wish to face. But not all teens do illegal things. I mean, I do and I'm not even sixteen yet lol. But I'm not addicted to drugs or alcohol. I just tried the **** for fun. But then again I am dating someone over the age of 18....
