Contesting Cannabinoid Hyperemesis Syndrome: How Narratives of Cannabis Shape Diagnosis Contestation and Treatment...

Cannabinoid hyperemesis syndrome (CHS) is characterized by the onset of cyclic bouts of severe nausea and vomiting in chronic cannabis users. As the number of CHS diagnoses rises, it is important to understand how people experience the disease. Using a narrative framework, we explore how the symbolic meaning participants associated with cannabis shaped the way they experienced diagnosis and treatment of CHS. To do this, we relied on semi-structured interviews with 24 people who self-reported having CHS. Participants had very positive perceptions of cannabis, which contributed to them contesting the diagnosis and resisting the treatment. They initially contested the diagnosis because they believed that cannabis was beneficial and helped with nausea, that claims about the harms of cannabis were part of a larger medical conspiracy to stigmatize it, and that they had different symptoms than those with CHS. They resisted treatment recommendations of abstinence and sought to continue using cannabis by trying new routes of administration, using only certain types of cannabis, reducing the amount or frequency of use, or substituting other substances. Findings point to the importance of understanding how narratives can shape the way people respond to diagnosis and treatment.
