There are no restrictions for caregivers as of yet. There are restrictions for dispensary agents they may not have a felony drug conviction. Dispensaries it seems will be allowed to grow at their dispensing location and one off site facility.
One thing for sure is it is a good thing no matter what the initial problems may seem to be. When things play out they don't go as planned especially in these states who legalize medical marijuana. People will figure out how to get the hardship vouchers and people will start growing when the law goes intoeffect. As the law stands all patients will be allowed to grow their own 60 day supply for the few months it takes to figure out the laws, then it will take even longer to figure out how to operate dispensaries, then you will have a whole big struggle about which towns want them and which don't also who gets to open and who doesn't. There will be winners and losers chosen and the losers will slow things down in court.
Also when it comes to conditions, there is an ambiguous ending saying anything which the physician sees fit. So while the diagnosed chronic illnesses are listed other co editions may qualify but not be listed. If I lived there I would get the ball rolling asap in January and find your doctor and get a rec and get registered with the state, then apply for a hardship voucher before dispensaries have a chance to open, this should at least buy you sometime to get in a few grows before dispensaries come and out you out of business. That is if dispensaries open at all, we are still waiting here in AZ and patients have been growing for the two years in the meantime.
