I still don't think the state should tell YOU where to get the meds. By being allowed to buy from ANYONE, as you can in most other businesses. YOU would have greater variety.
Just as an FYI, most consumable products (alcohol, medicine, food, for example) actually travel through very strictly-regulated supply chains. It's true that most other businesses can purchase stock from anywhere, but most other businesses similar to dispensaries can only purchase from a small group of licensed vendors. In the case of beer and alcohol, only from a distributor, which number about two dozen in this state. If I was making beer in my basement, I couldn't put it in a backpack and sell it to the local liquor store; those days are long gone.... and that option is about to be closed to commercial growers as well.
