In 2002, Clusterbusters was formed to take a pro-active role in researching for a cure for cluster headaches and find new and improved treatments.

Shortly thereafter, 6 advocates traveled to Boston and met with the administration of Harvard Medical School and convinced them of the importance of this research and they agreed to undertake the first psychedelic research project at their institution in 40 years.

Following extensive work building an incredible team, designing the scientific study protocol, collaborating on the research and submissions on the safety of the study, fundraising and navigating through the regulatory and legislative process, we embarked upon a journey of discovery.

On Feb 9th, 2004, and agreement was signed to begin research at Harvard University, the clinical study of  psilocybin as a viable treatment option providing, replicating results in a lab that had shown efficacious  results far better than anything currently available.

The first published results from this groundbreaking clinical study of this treatment appeared in the prestigious medical journal Neurology in June of 2006.

This has been an incredibly long and often frustrating process that included the discovery of BOL-148, starts and stops of every fashion, thousands of people finding relief with various new options and an unending determination to push forward past every obstacle. The growth of Clusterbusters into an active and successful advocacy group for the entire community, built with contributions from hundreds of people over the years that refused to let the words “can’t”, or “no” stop them from helping others.

Along the way we have added some incredibly dedicated advocates, we have lost one of our original research team members, Dr. Andrew Sewell, added extraordinary researchers and headache specialists to our team, overcome those that have tried to stop us and will continue to push forward.

Yes, it has taken 14 years but I am both proud and pleased to announce the following:


Adults with chronic cluster headache or episodic cluster headache (cycles at least 6 weeks long), age 21 – 65, needed for a research study investigating Psilocybin in the treatment of cluster headache.

ClusterBusters, a non-profit advocacy and education group, is participating in the recruitment of subjects for a pilot study investigating the safety and efficacy of psilocybin in cluster headache. This study is taking place at the Veterans Affairs Hospital in West Haven, Connecticut, an affiliate of Yale University School of Medicine.
