Receptor Profiles of Lysergamides related to LSD
Investigator: David E. Nichols
, PhD / Purdue University - West Lafayette, IN / Contact: David E. Nichols PhD / Sponsor: Heffter, Promind / Laboratory research, no human or animal subjects. It is well known that the nature of the amide function of lysergamides is critical to conferring activity and high potency onto these molecules. The N,N-diethylamide (LSD) is unique among all the known amides, both for the qualitative aspects of its effects and for its extremely high potency. This project is evaluating a series of lysergamides of varying amide structure using radioligand competition studies at cloned human brain neurotransmitter
receptors expressed in cell lines. The project seeks to identify in these data the possible reasons for the high degree of variability in activity of the various amides. That is, is there a specific subset of receptors to which LSD binds that less potent lysergamides do not? In addition, intracellular signaling pathways are being examined to determine whether all lysergamides activate the same intracellular biochemical events.

Guided, Structured, Group Use of Entheogenic Substances in Western Culture
(Doctoral dissertation) / Investigator: Roger Marsden / California Institute of Integral Studies, Clinical Psychology / Contact: Roger Marsden / Sponsors: 1998 Kranzke Scholarship; MAPS / What are the different frameworks being employed by entheogenic guides? How are these frameworks different from those used in the research of the 1960s? How do the variations in present day frameworks appear to affect the outcome? Regardless of one's individual assumption of the value of psychedelic work, it is happening in a variety of contexts across the planet. The investigator has completed all interviews in 3 guided, structured entheogen/psychedelic groups. Data analysis is complete (10 central themes extracted for the basis of discussion, i.e., preparation, integration, relationship of participants to guide, role of relationship of participants to each other, description of the actual sessions, relationship of the work to drug abuse issues, etc.)

Study Protocol (Amendment 1, Version 1: March 26, 2013)
MDMA-Assisted Therapy for the Treatment of Social Anxiety in Autistic Adults
There are currently no FDA-approved pharmacological treatments for autistic adults with social anxiety, and conventional anti-anxiety medications lack clinical effectiveness in this population. Based on anecdotal reports, MDMA-assisted therapy may be a suitable intervention for the treatment of social anxiety in autistic adults and warrants further investigation in a randomized controlled clinical trial.
Charles Grob, M.D., and Alicia Danforth, Ph.D.(c), will be co-investigators for this study.

Using BOLD fMRI to measure the effects of psilocin on brain activity and connectivity
Investigators: Robin Carhart-Harris PhD, Richard Wise, Amanda Feilding
, David Nutt
PhD. / Sponsor: Beckley Foundation / Supporting sponsor: MAPS and Heffter Research Institute / Contact: Robin Carhart Harris / This study is part of the Beckley Foundation/Imperial College Psychedelic Research Programme. It aims to discover how psilocin works in the brain by measuring increases and decreases in activity in different regions of the brain induced by the drug. Using analyses of functional and effective connectivity it will reveal network relationships between different regions of the brain and will show whether activity in certain brain regions is exerting a causal or driving influence over activity in other brain regions. These analyses may be very important for understanding the mechanism of action of psilocin. Based on the rationale of psychotherapeutic work with LSD and psilocybin/psilocin in the 1950s and 60s we will also address the hypothesis that psilocin lowers repression and facilitates autobiographical recollection. If this hypothesis is supported it will: 1) indicate that psilocin can facilitate the recollection of autobiographical memories 2) offer a biological explanation for how this occurs and 3) indicate how psilocin might be useful as an adjunct to dynamic psychotherapy.
A Pilot Study of Psilocybin-Facilitated Addiction Treatment
Investigators. Roland Griffiths PhD, Matt Johnson PhD, / Sponsor: Beckley Foundation / Contact: Roland Griffiths, PhD / This study focuses on overcoming nicotine
addiction in cigarette smokers. Psilocybin will be administered under highly supportive conditions to individuals who suffer drug dependence that has been resistant to treatment by conventional means. Participants will undergo several preparation meetings with session guides before two, day-long psilocybin sessions with a week's gap between them. Participants will meet with session guides the day after each session and weekly for 3 weeks after the last psilocybin session. To maximize the benefits of this research, we will also be looking to test the proposal that hallucinogen-induced mystical experiences may boost the immune system and thereby have important implications for health and well-being, by measuring cytokine markers of immune function before the first and after the last psilocybin session.
Effects of Psilocybin on Healthy Volunteers
Investigators: Roland Griffiths PhD, William Richards PhD, Una McCann MD, Robert Jesse / Sponsor: NIDA, Council for Spiritual Practices, Heffter Research Institute / Contact: Roland Griffiths, PhD / A series of studies is planned to investigate the effects of psilocybin in healthy volunteers. The first was a double-blind study evaluating the psychological effects of psilocybin relative to methylphenidate administered under comfortable, supportive conditions. After psilocybin, 61% of subjects met pre-established criteria, for a full mystical experience, and 31% reported significant fears during their psilocybin session. Two months after sessions, 71% of subjects rated their psilocybin experience as among the five most "spiritually significant" experiences of their lifetimes. 79% rated that it had increased their current sense of personal wellbeing or life satisfaction. Fourteen month follow-up data is being analyzed.
Continuing support for this research program is uncertain and the investigators are attempting to network with individuals or foundations that could help provide support.
