title: Prolonged depersonalization after marijuana use.
abstract: The author describes four cases of prolonged depersonalization that occurred months after marijuana use. Each occurred in the setting of a stressful life event. Depersonalization is a common experience during acute intoxication with marijuana, and these cases suggest that after the patients had experienced depersonalization, external stressors and intrapsychic factors may have contributed to its continued use as a defense mechanism.
