It's because the "Medical" side of the market doesn't actually exist. Want CBD heavy bud? Nope, not, "enough demand". Just higher and higher concentration of THC for the medical patients.
It's fake as hell. Not every medical patient has the same needs, so why the hell is it all the same weed?
Nowadays the hemp/CBD flower shops are more "medical" than any of the "medical" shops.
For here in Tucson, I recommend Healthful Flowers over on Speedway and Craycroft. The only legit "medically valuable" hemp/cannabis dispensary in town.
So yeah, to the "medical" dispensaries out there, it's adapt or die, and most are choosing to just make "medical cannabis" into "discount recreation cannabis" and wondering why their medical patients stop showing up.
