Bob is a paranoid schizophrenic. Bob used to be nuts but now Bob takes his medicine, Abilify, and leaves a happy, productive life at a top university in the midwest. If Bob were to use amphetamines heavily, could he get amphetamine psychosis? The only reason I ask is that amphetamine psychosis is said to have the exact same symptoms as paranoid schizophrenia so if Bob were taking medicine to keep those symptoms from happening the medicine might make it so he can't have the symptoms of amphetamine psychosis. Also, is it O.K for a doctor to prescribe amphetamines to treat add for someone who also has schizophrenia?
