As i said to someone else, you should'nt be smoking under someone else's house without they're knolegde. They're the one's who get in the shit for it, and its just not right, after this person has given you a roof to live under, and raised you. You could at least pay them back by NOT puting them at risk of going to jail without them even knowig. Who do you love more, weed or your parents? (thats if it is your parents your living with)

But if you want to toke i suggest not doing it in someone else's house without their knoledge, or have weed in they're house without they're knoledge. Mybe keep your stash somewhere else and don't toke in their house, that would be the sensible thing to do. But you will be caught, everyone get's caught eventully.
