Attention deficit is a conduct disorder, which means that its diagnosis relies entirely on assessment of patient's behavioural patterns. Since it's next to impossible to keep a patient under 24/7 observation, secondary sources have to be used. In most cases, the diagnostic process reduces to an "intake session" interview with a patient and a few multiple-choice diagnostic questionnaires.

So an AD* diagnosis is trivial to hack. Moreover, it's impossible to design a diagnostic process that's not easily hackable because, ultimately, everything will boil down to a subjective assessment of patient's behaviour, i.e. a "doctor's call". Furthermore, the more you restrict prescriptions and tighten the diagnostic criteria, the more you increase the risk of denying medication to "legitimate" sufferers. Since the guiding philosophy of the medical community prioritizes "helping people" over "prescription security", the problem of how to keep people from getting "illegitimate" prescriptions is ultimately intractable.
