Doctors at the Behavioral Pharmacology Research Unit of Johns Hopkins University are seeking volunteers for a study assessing the therapeutic value of the psychoactive substance, psilocybin, in sacred mushrooms (aka magic mushrooms). Volunteers with a current or past diagnosis of cancer are being sought. Our source notes: "Publicizing this trial has been very challenging so we are asking for your assistance to help us get the word out." We can imagine, given that "spaced out" <http://www.treehugger.com/files/2008/06/spaced-out.php> and the "hemp effect" <http://www.treehugger.com/files/2004/09/lets_change_the.php> come immediately to mind upon suggestion of beneficial applications for psychedelic substances.

But a quick review of the facts indicates that the study is legitimate. Certainly, the reputation of Johns Hopkins Medicine <http://www.hopkinsmedicine.org/Psychiatry/bayview/addiction_BPRU.html> gives the study gravity. We have also verified that the clinical trials are registered at the National Institutes of Health Clinical Trials <http://clinicaltrials.gov/ct2/show/NCT00465595?term=NCT00465595&rank=1> Website.

The theory: if a person is able to deal with their emotional fears and their mental fears about their disease, it frees them to focus on fighting the disease. Previous magic mushroom studies

<http://www.washingtonpost.com/wp-dyn/content/article/2008/07/02/AR2008070200972.html>

have shown that a single magic mushroom treatment under controlled circumstances can have positive mental health benefits for months or years later. At a minimum, the study hopes to show an improved quality of life for cancer patients who have used the psychoactive agents as part of a treatment program.

is linked to reassure potential volunteers who have fears due to the historical perceptions of magic mushrooms. According to our source, Principal Investigator and Johns Hopkins University Professor Roland Griffiths Ph.D. has been quoted:

the primary mystical experience might fundamentally change the perception of disease and perhaps quality of life in people distressed by life-threatening diagnoses of cancer.

Seeking Volunteers with a Cancer Diagnosis

to participate in a scientific study of self-exploration
and personal meaning

In recent years, scientists at some U.S. universities have been conducting studies using entheogens, resuming research in pharmacology, psychology, creativity, and spirituality that was suspended following the drug excesses of the 1960s.

Entheogens include the peyote cactus used by the Native American Church, the psilocybin-containing mushrooms used as sacraments in Mesoamerica, and certain other plants and chemicals. Such substances have been used for thousands of years in cultures from the Amazon to ancient Greece as a means of inducing non-ordinary states of consciousness for psychological self-exploration and spiritual or religious purposes.

These states of consciousness are most widely known in connection with practices such as meditation and prolonged fasting. Context seems to play a major role in shaping entheogen experiences and their consequences. Despite the well-known problems that can arise in unstructured settings, the risks of entheogens in research and ritual contexts have proven to be very small.

Researchers at the Johns Hopkins University are seeking volunteers with a current or past diagnosis of cancer who have some anxiety or are feeling down about their cancer to participate in a scientific study of self-exploration and personal meaning brought about by the entheogen psilocybin, a psychoactive substance found in mushrooms used as a sacrament in some cultures, given in a comfortable, supportive setting. Questionnaires and interviews will be used to assess the effects of the substance on consciousness, mood, and behavior.

Volunteers enrolled in the study will receive careful preparation and 2 sessions in which they will receive psilocybin. Structured guidance will be provided during the session and afterwards to facilitate integration of the experiences. The study complies with FDA regulations.

Volunteer must be between the ages of 21 and 70, have no personal history of severe psychiatric illness, or recent history of alcoholism or drug abuse, have someone willing to pick them up and drive them home at the end of the two psilocybin sessions (around 5:00 PM).

If you would like to discuss the possibility of volunteering, please call 410–550–5990 or email cancer@bpru.org <mailto:cancer@bpru.org> and ask for Mary, the study's research coordinator. Confidentiality will be maintained for all applicants and participants.

Johns Hopkins Psilocybin Cancer Study

BACKGROUND:
Patients with cancer often develop chronic, clinically significant symptoms of depression and anxiety that have a significant negative impact on the quality of their life. At their core, these symptoms often reflect a crisis in spirituality and religious faith. Spirituality may influence psychological coping in the face of advanced illness and is associated with decreased anxiety and depression. However, research demonstrating an association between spirituality and psychological response to serious illness is largely epidemiological and correlational, and little is known about translating such an association into an effective intervention. Occasioning a primary mystical experience may represent such an intervention. Primary mystical experience, often thought of as a gift of divine grace, creates the potential to produce transformative change in patients' attitudes towards illness and death, their quality of life, and the choices they make in the time that remains.

Psilocybin, a psychoactive substance found in Psilocybe mushrooms, and related compounds have been used as sacraments for millennia within certain cultures in order to induce mystical or spiritual experience. These subjective experiences share remarkable similarities to classical mystical experiences achieved by non-pharmacological methods such as prolonged fasting, prayer, and meditation. Although there is a long anthropological history of the association of such compounds with spirituality, little is known scientifically to validate such an association. Our laboratory recently completed a rigorous double-blind prospective study demonstrating that under supportive conditions, a high dose of psilocybin can help occasion a primary mystical experiences having lasting personal meaning and spiritual significance.

THE STUDY:
Our current study is seeking volunteers with a diagnosis of cancer to participate in a scientific study of states of consciousness brought about by psilocybin, given in a comfortable, supportive setting. Volunteers enrolled in the study will receive careful preparation and 2 sessions in which they will receive psilocybin. Structured guidance will be provided during the session and afterwards to facilitate integration of the experiences. Questionnaires and interviews will be used to assess the effects of the substance on consciousness, mood, and behavior.

VOLUNTEER POPULATION:
Patients are eligible if they have a potentially life-threatening cancer diagnosis without CNS involvement and they seem to be experiencing anxiety or depressed mood as a result of their illness. Patients with and without disease progression are eligible, but patients with no disease progression are only eligible if at least 1 year has elapsed since their diagnosis; for those with disease progression, patients should be between cancer therapies for at least a 1 month period (continuing hormonal therapy is acceptable). Patients who have decided not to undergo cancer therapy are also eligible. Our physician and screening staff will determine whether volunteers meet inclusion and exclusion criteria.

For individuals who are consented and screened, we will notify the referring physician: 1) whether the individual enrolled in the study or not, and 2) if disqualified, the reason for the disqualification.

Abbreviated inclusion and exclusion criteria - these will be evaluated by the study investigators

Inclusion criteria


Volunteers must:

·           Be 21 to 70 years old

·           Have a cancer diagnosis that is potentially life-threatening. Patients with disease progression are eligible. Patients with no disease progression or no disease recurrence are eligible if at least 1 year has elapsed since their diagnosis.

·           Have an ECOG performance status of 0, 1, or 2.

·           Have anxiety or depressed mood -- Psychiatric diagnosis will be determined by BPRU staff.

·           Be between cancer therapies or have independently decided to not undergo direct cancer treatments, such as chemotherapy and radiation, for at least an approximately 1 month duration (2 weeks before the first psilocybin session through the 1 week follow-up after the second psilocybin session). Continuing hormonal therapy for breast or prostate cancer is acceptable. If he/she subsequently decides to initiate or resume treatment for cancer (such as chemotherapy and radiation, but excluding hormonal therapy for breast or prostate cancer) at any point before the second psilocybin session, then the patient will be withdrawn from formal data analysis. However follow-up data will continue to be collected for the purpose of maximizing the obtaining of pilot information. After completion of the second psilocybin session, if a patient decides to resume or initiate treatment, he/she will not be withdrawn from formal data analysis.

·            Agree that for one week preceding each psilocybin session, he/she will refrain from taking any nonprescription medication, nutritional supplement, or herbal supplement except when approved by the research team. Exceptions will be evaluated by the research team and will include acetaminophen, non-steroidal anti-inflammatory drugs, and common doses of vitamins and minerals.

Exclusion criteria

General Medical Exclusion Criteria
