Abstract
Three cases of psychosis following the ingestion of morning glory seeds have been presented in this paper. The similarity of these reactions to those following the ingestion of lysergic acid diethylamide (LSD-25) has been noted and related to the fact that morning glory seeds contain chemically related substances.
We have reviewed our findings in relation to the structural theory, indicating changes seen in id, ego, and superego functioning. Our findings indicate that these drugs have their most marked action upon the synthetic function of the ego and that the long lasting effects appear due to disturbances in this group of ego functions rather than organic changes.
