I caught my 12 year old son smoking?

I was driving my son to see some friends. Now he's usually a good boy. I mean, he's done bad stuff in the past but still. When I dropped him of I hugged hi goodbye and let him go catch up with his friends. My son was 12 years old, and he resembles his me mostly. I smiled at this. Later that day the sky grew dark with ominous rain clouds. It was storm weather, and my son had no way to get home so I went to pick him up. When I got there what I saw terrified me. He was smoking, A joint. He just stared at me when I caught him. We drove home in silence with nothing but the roaring wind and pitter-pat of raindrops. When we got in the house I exploded. "What happened to you?" I asked. My son broke down. "I'm sorry daddy" He sobbed. I knew what I had to do. So I leaned close and whispered in his ear, "You're moving with your auntie and uncle in bel air."
