I am not betting my farm on it.
Walgreens have announced they intend to sell Weed as an alternative drug, and if that occurs, all these Mom and Pop stores, with the small farms producing for them will be lost. Walgreens is not going to depend on thousands upon thousands of family farmers to supply for them, that will go to big agriculture for a dependable supply, and lower cost, and soon it will just be a crop, like any other crop.
The demand right now is too high (pun intended) and the money to be made on it is too big. This is just like organic farming. It used to be family farms, then they created a certification process, and now organic is big agriculture too. This is going in the same direction.
