How much marijuana can you buy from an AZ dispensary?

Arizona limits it to 2.5 ounces of marijuana per 2 weeks, or 14 days, that you can buy from dispensaries. They track it when you use your marijuana card, and that's how they regulate how much you can buy and use each month, which is capped at 5 ounces of medical marijuana. (I found this information at: cannabisdoctorsnetwork.com).
