For those who says haldol should be banned...
When a schizophrenic/psychotic person experiences psychosis or oneiroid, with everything that is left from who they used to be, they pray for it to end. Yes, haldol causes depressive symptoms, but I bet it feels so sweet when oneiroid, e.g. the single most painful sensation one can experience, fades away. Depression is MUCH preferrable to psychosis.
