This framing is terribly paternalistic. If a person is taking a drug, they themselves are who is possessing and using it. They aren't some mere passive subject for doctors to be acting on. Furthermore, they shouldn't be forced to convince some doctor-bureaucrat they have some specific medical condition, or even a "medical condition" at all, to be allowed the treatment they'd like to try.
