Ok so I am 23 and live in Washington state I have a prosthetic leg and because of that I have constant back pain and I don't want to take prescription pills because I can not function on them at work! I am considering getting my card. I have a doctors appt on Monday and am wodering how I would go about bringing it up should I get a perscription for pills and then go to cbr and get switches to mmj? Any help would be greatly appreciated thanks
