I think they might test negative but then you know not to waste your time messing with the meds and try something else instead. I mean for sz if you don't have a dopamine imbalance of some sort why use a dopamine blocker....I mean yeah it will sedate/restrain people it if you're not treating an underlying condition then that brute force sedation becomes a lot harder to justify. Right now it's closer to society having a mute button for people they don't want to deal with than any sort of science based medicine.
