Gribble v. Buckner

How later courts describe this case

• “[T]here is considerable overlap between a psychotic person’s inability to understand and his ability to control his behavior.”
• narcotics addiction, without more, raises no issue of mental disease that can be used as a defense to prosecution for narcotics offenses
• whether agency relationship exists turns on whether agent acts on behalf of and is subject to control of principal
• issue of insanity cannot go to jury where evidence is only that defendant suffers from a narcotics addiction which does not, standing alone, fall within scope of mental disease or defect
