I was kicked out at 16 because of my attitude, which was due to my drug/alcohol problem. It took me 11 years to get sober, but I did it - eventually
I can tell you that I never would have gotten sober under my parents roof. Even my recovering alcoholic father, I wouldve snuck booze past him. He mightve been smart enough to check shampoo/conditioner bottles, but I highly doubt it. I'd find a way, and id try anything...absinthe is the same colour as mouthwash, very strong and smells similar too....thats a great cover, id take the dog for extra walks to score and smoke weed. Wait till mum had gone to bed till I could finally smoke in my own room! Love for my parents or anyone didnt come into the equation when i was in love with a substance. I took booze/drugs into all sorts of places I wasnt supposed to, their houses were no different. Addiction is so consuming and as a result, I was extremely selfish. Noone could stop me but me.
Good Luck.
