Welcome Robert deuce
being sick usually helps...and its not really a card but rather an exemption from prosecution (section 56)....well at least until the gov gets off its collective ass and legalizes it...which should in reality not take very long at all....but being the job makers the government are,,,,is taking forever of course....
personally I would wait and just fly under the radar if you can....it wont matter much soon..
if you can't ...then you need to see your doctor ...and do some reading on here...
