Chronic cannabis use is increasingly associated with recurrent bouts of vomiting, officially classified as cannabinoid hyperemesis syndrome (CHS).1 The condition affects patients who have been regularly using cannabis products for months or years.1 The new ICD code helps doctors identify cases more consistently and gives researchers a clearer picture of the prevalence of the condition. Symptoms of CHS include persistent or recurrent bouts of nausea, vomiting, abdominal pain, dehydration, and food aversion.1 Patients often resist this diagnosis, and the exact causes of the condition remain unclear. Relief may come from unusual sources, such as a hot shower or capsaicin cream. Recognition of CHS is important for proper treatment and improved care of patients with this condition.
