I Have Degenerative Disc Disease Which Causes Me A Great

I have degenerative disc disease which causes me a great deal of pain even after 3 back surgeries. I am currently taking 10mg of methadone HCL at bedtime for the pain. I also am dealing with depression, anxiety and panic attacks and have been prescribed 60 mg of Cymbalta once a day, 1 mg of Clonazepam twice a day and 25 mg of Atarax twice a day. I have also had open heart surgery for mitro valve with regurgitation. The valve was repaired with no leakage. I still have a irregular heart beat. In your professional opinion would marijuana be a good option for me to take instead of all these medications. I don't want to smoke the marijuana, but would be willing to try it in pill form if I would receive more benefits from it than what I am currently taking. Thank you.
