Pharmacologically speaking, classifying Adderall as a hard drug by industry terminology standards requires taking the patient into account, the dosage, and its effects on the patient. In the case I was referring to (mine) it is not a hard drug.
The chemical imbalance I refer to isn’t something that is easily and REPEATABLY tested for and prescription of the drug itself is heavily guided by the individual respondent because that is how most psychiatric diagnostics are performed. The chemical imbalance is not the exact same between patients, and ADD/ADHD could be classified as multiple physiological conditions that all overlap into a single group of symptoms. For the purposes of treating it, prescribing a medication that treats a large subset of the underlying causes with no permanent adverse side effects if you treat the “wrong one” is largely good enough for most medical systems. Follow up appointments with providers checking with patients to find the right medication for their brain is part of that process.
So yeah, you can fill out a questionnaire and get amphetamines you don’t need, or don’t treat your specific condition. That doesn’t invalidate the scientific research that has linked the symptom to the one of n chemical causes in the brain.
So in discussions of both philosophical introspection of our society as well as academic discussion of drugs, my original comment is entirely relevant to those informed on this ONE specific mental disorder, of which there are MANY more that are equally as nuanced.
