Clusterbusters

Clusterbusters is a long-running U.S. disease-community organization for people living with cluster headache and their families. It combines patient support, treatment education, research support, and advocacy around access to effective therapies, including psychedelic options such as psilocybin and LSD.

For Blossom, Clusterbusters fills an important gap because it is one of the clearest headache-focused patient stakeholders with explicit psychedelic relevance. Its public work links patient registry infrastructure, annual conferences, and advocacy around both conventional access issues like oxygen and psychedelic research and treatment pathways.
