It is possible but you need a doctors sign off on that license. When I lived In California 16 years ago medical use was just that only legal for medical. I went in and working for UPS said I had bad back problems and couldn't sleep bam no problem 150.00 and your good but the teamster union had a no random testing rule this was 10 years ago it may have changed. Unless you were in a accident then you pee on the spot now your job is in jeopardy. Those were just a money grab you renewed every year for 50.00 then it went up to 200.00 more than the original fee. In Gordon's case I am thinking by NFL rule that wouldn't fly just for the fact every player could claim that use because every player is in pain every season. It would be up to the NFL to kill that policy I would imagine.
