Just found aluminium foil pieces, a lollipop, a card, and an empty water bottle with a hole in it in my nephew's carWe also found liquor in the trunk, just to give you an idea of his interestsAre those three items a sign of him doing weed? We do not smell anything in the car, but his behavior lately and the fact that he has a new group of friends is making us wonderLet me know, thanks.
