You're assuming that the supply will be reduced. I don't believe that to be true. Hell, there are still underground growers supplying dispensaries now! More people getting their licenses means more people growing and more supply!! You're assuming that they will regulate who can grow, but its in the amendment that patients can grow 6 plants, so I don't think that's going to be changing soon. The supply will be there it just may be coming from a different place.
