CAn't you be honest with him?Doctor patient confidentiality?You're legal, so why worry?
i told him i smoked pot. he told me not to smoke pot with a broken leg because it will slow healing. i asked if it was the thc or the smoke that was the worry. he said the smoke, "but unless your going to put it in your butt, then don't do it". i tried to tell him you can eat it but he wouldn't listen. i told me wife i should just tell him but she says he would probably think even less of me.
