It used to be the policy of prisons and larger county jails in Illinois, for the institution to have their own doctor, who would refuse mentally ill people many kinds of psychological medications and make substitutions. This resulted in nearly everything being substituted with Trazadone at the time (they may have switched to substituting to Seriquill now). This included taking inmates off of MAOI inhibitors, cold-turkey, something that is damaging to your brain.
