I'll chime in here too - I have been legal in Washington since last fall. I was getting tired of the itchiness and constipation whilst on opiates...and in general was not happy with how I felt on them.

One day my massage therapist asked if I wanted to try some THC-infused massage oil on my nerve damaged foot - and it worked so much better than the expensive, custom-compounded cream that my Doc Rx'd me, I have been using it since. Eventually I decided to try smoking as well - and have never looked back. I use a very high CBD strain, that takes most of my nerve pain and allodynia away, yet doesn't make me high like a high THC strain would. After a week or two of regular use, my foot swelling was minimal, my pain/sensitivity was substantially lower, and I have been a MUCH happier person (not to mention I got my libido back)! Since giving it a try, I am now completely off my long-acting ER opiates, and am down to about 1/2 as much as I was on for my IR opiates...and still tapering. It doesn't work for everyone, but it has worked well for me, and worth a shot if you are not happy with your current pain management meds.
