Get ready for a tons of dirt cheap pot then. This is a product that can be grown by the acre and sold by the gram. The previously existing price structure was driven by the risks taken by the producer because of the product's illegality. With the legal impediments removed expect everybody and his dog to pile on the supply side, driving the grey-market price down to not much above production costs, which are minimal. And no, "regulation" isn't going to change that - the previously existing prohibition couldn't be enforced, so there is no reason to think "regulation" can be.  Smoke 'em if you got 'em, friends.
