The hallucinogenic effects of Brugmansia were described in the journal Pathology as "terrifying rather than pleasurable".[31] The author Christina Pratt, in An Encyclopedia of Shamanism, says that "Brugmansia induces a powerful trance with violent and unpleasant effects, sickening after effects, and at times temporary insanity".[20] These hallucinations are often characterized by complete loss of awareness that one is hallucinating, disconnection from reality (psychosis), and amnesia of the episode, such as one example reported in Psychiatry and Clinical Neuroscience of a young man who amputated his own penis and tongue after drinking only 1 cup of Brugmansia tea.[32]
