I found pot in my parents room?

First off, I wouldn't call the cops. Think about this for a minute or two. If you were to call the cops, they would be arrested and the you would be put into a foster home and probably become a sociopath in the future. Just sit down with them and talk about it. Better yet, research about it online. The pros over weigh the cons big time. If you are open to learning, you will walk away from this experience laughing. It's not that big of a deal, it's as if they had a cigarette or a shot of vodka sitting in their cabinet. I hope that this helps and please don't do anything drastic.
