Wow, you sound like a older version of me. And my parents have caught me before but its never been because it was obvious I was stoned. it's because they search my room and go behind my back on a regular basis. Even when I took a long hiatus from drugs, they still found some reason to suspect that I was using them and I would constantly find evidence of them going through my stuff. That is what is not right. They are just as guitly for violating my privacy as I am for violating their rule.
