Mental health issues are a leading cause of disability, and they remain inadequately treated worldwide.

The modest effectiveness of existing treatments such as antidepressants and traditional psychotherapy approaches show us that there is an urgent need for more effective treatments for conditions such as depression, alcoholism, smoking cessation, and end of life suffering.

Early studies of psychedelic-assisted therapies for these conditions have demonstrated much larger and durable effects compared to existing therapies suggesting that there is great potential for psychedelic-assisted treatments to revolutionize the treatment of mental health and behavioral disorders.

Vision & Mission

VISION: Pacific Treatment & Research In Psychedelics (TRIP) is dedicated to the development of psychedelic-assisted therapies and the scientific exploration of how psychedelic medicines and expanded states of consciousness can be harnessed to change behavior, improve brain health and optimize quality of life.


  • Develop safe and effective psychedelic-assisted therapies for behavioral health conditions including anxiety, depression, addiction, PTSD, grief and related disorders.
  • Advance psychedelic science and our understanding of the neuroplastogenic potential of psychedelic medicines for treating mental health disorders, brain injury, neurodegenerative conditions and pain syndromes.
  • Help expand access to those in need of psychedelic-assisted therapies including underserved and under-represented communities.
