From my personal experience I can tell you that it seems to give me some relief. I am on oral Ketamine for my RSD pain but I do still have some break thru pain mainly in the evening. This is when I will use the weed. I have morphine to help with this pain but have found it to do little good for me. I do find that the weed really relaxes me....to the point of making me sleep. Needless to say, it must help my pain if it helps me to sleep. On a negative note, here in VA we are not a State/Commonwealth that has a legal medical marijuana law on the books so I am unable to do this legally.
