Main difference between Manic-Depressive Illness (Bi-Piloar) and Schizophrenia
The predominant clinical symptoms involving disorders of mood rather than disorders of thought
Why is it so common to see schizophrenia begin after a person has used mind altering drugs?
- Both drug abuse and the onset of schizophrenia occur in the same age range of the late teens and early 20s. The percentage of people in this age range who have at least smoked a few joints is very high.
- Second, and more important, is the common sequence of people developing the early symptoms of schizophrenia and then turning to mind altering drugs to provide a rationalization for what they are experiencing.
Hendricks Decision

Law upheld by US Supreme Court in 1997
