United States Court of Appeals for the Fifth Circuit
739 F.2d 994 (1984)
Robert Lyons (defendant) was federally indicted on 12 counts of knowingly and intentionally securing controlled narcotics. Lyons proffered evidence that he became addicted to pain-killing narcotics prescribed to him in order to treat medical conditions. Lyons further offered to present expert witness testimony that his addiction affected his brain physiologically and psychologically to the point that Lyons lacked substantial capacity to conform his conduct to the requirements of the law—thus raising an insanity defense. The trial court excluded the proffered evidence and Lyons was convicted and he appealed.
