On the 18th of April I have broken my right collar bone and I have got until mid July to wait for it to completely heal. I am wearing a sling and it doesn't really hurt that much anymore at all. Last time I have seen my doctor a few days ago he told me to quit smoking marijuana for it does not help for my bone to heal. I am a musician and I want to make a professional career out of it I play different instruments so I need my arms badly on the other hand I don't want to quit so is it true that the active ingredient, THC in weed affects not just your brain but also your bones growth? Thanks :)
