Hi All, I think that my roommate is addicted to pain killers. He was prescribed them after an injury last year but continues to take them. I know his prescription has run out but I still see him with them regularly-- what is the best way to approach him about this? We've lived together for over 4 years so we are pretty close but I don't want to offend him. I'm worried about his health and just want to make sure he is safe.
