Overview

CEP is a network of health economists dedicated to achieving the potential of psychedelic therapies for high-priority mental health conditions. Through the application of policy-relevant economic analyses, CEP seeks to enhance clinical outcomes, increase efficiency of service delivery, and increase access to these promising therapies for everyone who can benefit. Here is a partial list of current projects:

• In collaboration with the Psychedelic Mental Health Access Alliance (PHMAA) evaluating the economics of  care delivery models for marginalized individuals, including Medicaid-fundable models; and developing a uniform set of service delivery variables for psychedelic services providers.

• In collaboration with the Usona Institute, modeling the cost-effectiveness of psilocybin-assisted psychotherapy to treat major depressive disorders.

• In collaboration with Johns Hopkins University’s Center for Psychedelic and Consciousness Research, evaluating the cost-effectiveness of psilocybin-assisted therapy for smoking cessation.

• In collaboration with the Sheri Eckert Foundation, evaluating changes in health care use and costs in people accessing Oregon’s s state-sponsored psilocybin services.
