Hi there ~
I understand your concerns. I believe that you should stop the marijuana use since you are having a problem with dependence on the substance. I also believe that you might be able to experience less pain and undergo pre-op and post-op recovery better if you are able to consult a doctor who can treat your drug dependence
problems. I believe that you need to consult a medical doctor
as soon as possible to get answers to your questions.
I hope this helps. Take care and have a lovely day!
