Clinical Resources for Cannabis Health Adverse Outcomes: Enhancing Health Care Providers’ Ability to Intervene on Cannabis Hyperemesis Syndrome and Cannabis Induced Psychosis

Patients presenting with cannabis-related adverse events (AEs) and other problems are growing more prevalent in health care settings across the U.S. and Canada, increasing the burden on providers and health systems. In a recent survey conducted among health care providers in Washington State, thirty-five percent of respondents reported seeing cannabis AEs and use-related problems frequently (at least 2-3 times a month). Severe cyclic vomiting was most common (70% reported it ever occurred) and was second to psychosis as “most serious” (33% and 34%). According to study participants, expanding access to clinical guidelines, validated tools, referral pathways, and specialized training could enhance their willingness and capacity to screen and intervene effectively on such AEs.  

In partnership with community-based organizations, clinicians, and experts, this project aims to develop, test, implement, and disseminate resources for health care providers and patients about cannabis hyperemesis syndrome (CHS) and cannabis-induced psychosis. Resources will include a set of evidence-based clinical pathways, educational materials for professionals on how to communicate with patients, and discharge and referral protocols. Resources will be developed, tested, and disseminated.
