Cannabis is the most widely used illicit drug in the world. In France, cannabis use has been increasing among youth since 2011, in both experimental use and regular consumption. A distinct syndrome, characterized by recurrent vomiting associated with abdominal pain and compulsive bathing, has been increasingly recognized in adult chronic users. ⋯ To date, the specific etiology of CHS is unknown as is the pathophysiology of improvement with hot baths. All youth presenting with cyclic vomiting should be questioned about cannabis use and compulsive hot bathing. The early recognition of this syndrome will save unnecessary and invasive investigations.
