Religious or Spiritual Problem | Drug: Psilocybin | Phase 1 |
This randomized-controlled pilot study uses a wait-list control design. A wait-list design includes a control group that is assigned to a waiting list to receive an intervention after the active treatment group does. In this study, the active group will receive the psilocybin at weeks 5 and 9 and the wait-list control group will receive psilocybin at weeks 30 and 34. The wait-list control group serves the purpose of providing an untreated comparison for the active treatment group, while at the same time allowing the wait-list participants an opportunity to obtain the intervention at a later date.
This study's procedures include screening, preparatory meetings, psilocybin sessions, and follow-up assessments. A large battery of behavioral and psychological measures will be assessed throughout. The study team will consent and enroll up to 86 subjects to obtain a total of 12 completer participants as well as 2-3 family members or friends per study participant who can assess said completers on the Observer Rating Form (COM-R). This number will account for screen-failures and dropouts as well. The 12 participants will be randomly assigned to either an immediate participation group (N=6) or a 6-month delayed participation group (N=6). Although statistical power calculations show that 12 participants will be sufficient to detect the major effects anticipated in this study, the sponsor of this study (The Council on Spiritual Practices) is concurrently funding Johns Hopkins University School of Medicine to conduct a methodologically identical study with 12 additional participants (IND #59009). This will permit the two sites to collaborate post study completion and combine the data from the two studies to provide statistical power to detect even more subtle effects of the psilocybin intervention. Twelve volunteers (6 from each group) will participate at Johns Hopkins and 12 at New York University. Randomization and data analysis will be conducted at New York University.

Experimental: Immediate Participation Group
Participants will begin psilocybin intervention immediately after study enrollment.
|
Drug: Psilocybin
Participants will receive 20 mg/70 kg of psilocybin in the first session and will receive either 20 or 30 mg/70 kg in the second session. |
Active Comparator: Delayed Participation Group
Participants will begin the psilocybin intervention 6 months after study enrollment.
|
Drug: Psilocybin
Participants will receive 20 mg/70 kg of psilocybin in the first session and will receive either 20 or 30 mg/70 kg in the second session. |
- Interim Questionnaire [ Time Frame: 6-Months after enrollment ]This questionnaire asks about experiences and changes in attitudes, mood and behavior that occurred during the past 5 months. The questionnaire includes questions about salient spiritual experiences, changes in spiritual practices, changes in attitudes, moods, social interactions, and other behaviors related to participants' religious/spiritual vocation.

Ages Eligible for Study: | 25 Years to 76 Years (Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | Yes |
Inclusion Criteria:
-
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.
Exclusion Criteria:
-
General medical exclusion criteria for religious professionals:
- Women who are pregnant (as indicated by a positive urine pregnancy test assessed at intake and before each drug session) or nursing; women who are of child-bearing potential and sexually active who are not practicing an effective means of birth control.
- Cardiovascular conditions: coronary artery disease, stroke, angina, uncontrolled hypertension, a clinically significant ECG abnormality (e.g., symptomatic atrial fibrilation), or TIA in the past year
- Epilepsy with history of seizures
- Insulin-dependent diabetes; if taking oral hypoglycemic agent, then no history of hypoglycemia
- 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.
