The problem with requiring a prescription is too many people can't afford to see a doctor, due to the high cost of insurance.
And those with Medicaid / Medicare are often stuck with using clinics with no doctors.
I have a couple friends with drastic medical problems, who are stuck in that situation ... so can't get "medical" marijuana.
But they can get "recreational" marijuana to relieve pain, stress, and lessen anxiety attacks.
btw - California is making "recreational" use legal.
I hear some of the "wine tours" will be adding marijuana to the tour. Some are figuring out what wine goes with what marijuana product. LOL
