On this episode of the Bioactive Podcast, Dr. Riley Kirk is joined by Dr. Codi Peterson and Megan Mbengue to discuss their newly published paper on Cannabinoid Hyperemesis Syndrome (CHS). Drawing from their recently published research and clinical experience, they explore what CHS is, how it presents, and why it is often misunderstood or misdiagnosed. The conversation covers early warning signs, the prodromal phase, and the severe symptoms patients experience, including the challenges faced in emergency care settings. They also address common misconceptions around cannabis use patterns, frequency, and the role of THC in the development of CHS.

They discuss key factors influencing CHS, including consumption methods such as vaping versus flower, rapid THC absorption, tolerance, and the impact of high-potency products. The discussion explores myths around pesticides, synthetic cannabinoids, and the importance of distinguishing correlation from causation in cannabis-related health outcomes. Additionally, they examine strategies for reducing risk, including tolerance breaks, balanced use, and patient education without stigma. The dialogue further highlights the importance of compassionate care, proper diagnosis, and the role of healthcare professionals in bridging the gap between cannabis use and medical understanding. Finally, they touch on future research directions, the importance of data collection, and how education can shape safer, more informed cannabis use.

This is a conversation for anyone using cannabis regularly, healthcare professionals seeking to better understand CHS, or patients navigating unexplained symptoms. Whether you're exploring cannabis for wellness or working in clinical settings, this episode provides critical insight into responsible use, early warning signs, and the evolving science behind cannabis-related health outcomes.
