The Division of Behavioral Health and Recovery at the Health Care Authority has a scientific advisory group, the Prevention Research Sub Committee (PRSC). The PRSC is co-chaired by Northwest PTTC Directors Dr. Brittany Cooper and Dr. Kevin Haggerty. In March 2020, the subcommittee invited a workgroup of researchers to better understand the scientific evidence of the health and behavioral risks of high potency cannabis use. The intent of the workgroup was to help inform policy and practice with the best science available. The workgroup was organized and chaired by Dr. Bia Carlini at the UW Alcohol and Drug Abuse Institute. Dr. Carlini invited scientists in the field to present the evidence to each other in order to come to a consensus statement. Researchers including Washington State University and the University of Washington as well as others, worked together to address this important question. The charge of the workgroup was to provide policymakers with a summary of evidence on risk to health and behavior related to high potency cannabis. The report provides a consensus statement related to the health and behavior risk of high potency cannabis and offers a summary of research evidence supporting the consensus statement.  Download the Cannabis Concentration and Health Risks: A report for the Washington State Prevention Research Subcommittee (PRSC)
