i went to the LA canna cup in Feb... you really dont need a med card... they give you a clip board with a form jus write down a friends med number or make one up... think about how many fuckn stoners are gonna be there... they dont give a flying fuck... its a stoner event... u can even bring in your own meds... my friend didnt have a med card he jus wrote a fake number...he bought and smoked herb had a blast....shit even i wrote fake info.. vendors are there to make as much money they can in those two days....
