I was diagnosed with degenerative disc disease and arthritis in my upper back and neck, and I'd like to try mmj to see if it will work better than the drugs my doctor prescribed. I've made an appointment with a Medicann clinic. They say that I need to either bring some sort of document from my doctor that says what condition I'm being treated for, or bring my prescriptions. My current prescriptions are Ultra* and Skela*in. Will it be enough to bring those to the clinic, or do I need to contact my doctor? I'm not sure that my doctor would approve of mmj.
