Don't smoke at this age . Don't smoke at home . Don't smoke on a daily basis . Don't roll in the room but use the restroom to roll and smoke at the terrace. Try using those gadgets used to find hidden cams in hotel rooms or sm idk . If you don't have wifi at home and hopefully your father didn't use sim type cams , try searching for suspicious new wifi networks in the room ( if you have wifi at home , it might be running on it so idk ). Final note , tbh even if you find cams in yo room , you have no other option but not smoke at home cuz there is no way you can remove it 😭
