Can't speak for diabetic neuropathy, but since the same effects on the brain will happen wrt to "regular" neuropathy I would imagine that similar effects on certain nerve receptors will happen, plus you have the anti-inflammtory aspect, especially on blood vessels, AND the vasodilation which should also help with any associated circulatory problems.
So I would imagine that MMJ, especially CBD as that has been proven by numerous trials, COULD have a beneficial effect regarding the pain control, with potential longer term benefits due to things like the vasodilation.
Is say "COULD" because, like with any form of medication, whether it is a herb or a pharmaceutical, what works with one person may not work with another.
