Basically wondering does marijuana smoke affect the healing process of broken bones? Background: So I broke my right ankle at the bottom of my tibia and tore the ligaments in both. (Racing Supercross). I was in a cast on the right for 5 weeks now with more x-rays still broken but doctor gave me a walking cast (instead of regular cast) for an additional 4. I have been smoking rather often to help with pain (in beginning) and now b/c I'm so bored and have nothing else to do. But I'm beginning to think maybe it's hurting me in the long run. I did some research and found that cigarette smoking affects you greatly in the healing time of your broken bones. But what about marijuana smoke?
