Ok i smoke in my room too. There is hardly any smell at all if you breathe out the window. I do this like everyday and my parents are stupid parents they alawasy check on me and stuff. I have my fan running and after i smoke i spray lysol, axe cologne anything to cover up if there is a smell. Pipes and bongs arent that smelly. Joints and Blunts are super smelly so i never smoke them in my house only at parties.
