I don't live in California, but AFAIK prescriptions aren't per order. You get a medical card via a doctor's recommendation, and then present that card to become a member of a medicinal "club" (which probably requires validation with the state that you are properly licensed). If I understand correctly, Meadow then interfaces with these clubs to provide expedited delivery to their members. Essentially, the hard verification work has already been done since only members (with medical cards) can order from the clubs Meadow delivers for.
