That's one reason I never tried to grow when living with parents. I grew up in a foster family, and man, they were strict. I came home on leave from the Army, and one of my foster brothers was growing pot in his room (which was my old room). I couldn't believe it. Well, his plants weren't nearly done, and he asked me for a little, so I gave him a quarter ounce. He got caught with it, and promptly told my foster parents that I gave it to him, which was totally unnecessary. They made me move out for the rest of my time on leave, so I stayed at a hotel (which wasn't bad, actually, although it was an expense I hadn't anticipated). But I was really pissed that he ratted me out, so I told my foster mother about his little grow. What goes around comes around.

Hope you don't get in too much trouble. Compared to having a kid with a drinking problem, I think a little pot is pretty benign, but they may not feel the same. ;(
