The Effects of Psilocybin-Facilitated Experience on the Psychology and Effectiveness of Religious Professionals

Completed · Phase 1

Conditions studied: Religious or Spiritual Problem

In brief

The current protocol is a pilot study of the effects and possible utility of psilocybin-facilitated experiences for professional religious leaders. We hypothesize that religious professionals, given their interests, training, and life experience, will be able to make nuanced discriminations of their psilocybin experiences, thus contributing to the scientific understanding of mystical-type experience. As we better characterize the phenomenology of psilocybin-induced mystical experiences, we may apply this knowledge to improve potential treatment studies in the future. A primary objective is to investigate changes in psychological functioning, spirituality, health, well-being, prosocial attitudes and behavior in professional religious leaders that may occur after receiving psilocybin under supportive conditions. A secondary objective is to determine whether participants who report having had the strongest mystical-type effects during psilocybin sessions will show the largest positive changes in the Interim Questionnaire.

Who can join

Age: 25 and older, up to 76. Sex: any. Healthy volunteers: accepted.

You may qualify if…

• Inclusion criteria for religious professionals:
• 25 to 76 years old

• Agree to consume approximately the same amount of caffeine-containing beverage (e.g., coffee, tea) that he/she consumes on a usual morning, before arriving at the research unit on the mornings of psilocybin session days. If the participant does not routinely consume caffeinated beverages, he/she must agree not to do so on session days.
• Agree to refrain from using any psychoactive drugs, including alcoholic beverages and nicotine, 24 hours before and after each drug administration. The exception is caffeine. Participants will be required to be either a non-smoker or a non-daily smoker.
• Agree not to take any PRN medications on the mornings of drug sessions
• Agree not to take sildenafil (Viagra®), tadalafil, or similar medications within 72 hours of each drug administration.
• Agree that for one week before each drug session, he/she will refrain from taking any nonprescription medication, nutritional supplement, or herbal supplement except when approved by the study investigators. Exceptions will be evaluated by the study investigators and will include acetaminophen, non-steroidal anti-inflammatory drugs, and common doses of vitamins and minerals.
• Have no or limited lifetime use of hallucinogens. Preference will be given to enrolling volunteers with no prior use. If we decide to enroll a volunteer with prior use, preference will be given for those who report the fewest exposures or the least enduring effects from such use.

You may not qualify if…

• Currently taking psychoactive prescription medication on a regular (e.g., daily) basis
• Currently taking on a regular (e.g., daily) basis any medications having a primary centrally-acting pharmacological effect on serotonin neurons or medications that are MAO inhibitors. For individuals who have intermittent or PRN use of such medications, psilocybin sessions will not be conducted until at least 5 half-lives of the agent have elapsed after the last dose.
• More than 20% outside the upper or lower range of ideal body weight according to Metropolitan Life height and weight table
• Psychiatric Exclusion Criteria for religious professionals:
