Marijuana

I have a question for those that have done tons is research here, and there's lots of you. I am a disabled veteran (no PTSD), but I take seven medications and get injections regularly for injuries sustained in my years of service, not to mention the therapy. I saw that governor Edwards signed a bill to allow the VA to prescribe marijuana to veterans and there is also the Veteran's Equal access act, but when I mentioned marijuana in lieu of the seven medications, I was immediately shut down by the VA doc because she said its a federal matter. Any suggestions of how to move forward?
