I have a friend in AZ. He was telling me you can only grow if there's no dispensary near you or something?

Here in CA they are trying to close all dispensaries supposedly. Our law gives us the right to grow but never said anyone could open a brick and mortar store to dispense it. At least that's what I get out of the hub bub.
Hopefully I'll be self sufficient by the time they close them, if they do.
