All the dispensaries I've been to have you sign a paper listing them as a care giver. If your in Cali. and have a rec your good to go. The only reason you need a written one is it's easier to get into a club. A verbal is supposed to be just as good. (haven't tried it out on any cops yet though). If your growing just stay with in your counties possession limits and you should be good to go. I don't like the idea of signing up with the government, If something goes wrong (wrong people get elected) I don't want to be on the list of easy busts....
