Schizoaffective DisorderSchizoaffective disorder is a mental condition in which the patient typically exhibits depressive and manic symptoms, along with periods marked by hallucination, delusion, and abnormal speech and behavior. Like most mental health conditions, schizoaffective disorder requires extensive treatment from a medical doctor. Patients in this condition may benefit from the use of moderate amounts of marijuana as a means to control many of the urges surrounding the condition. Of course, the use of marijuana will first have to be approved by a doctor.
