<unk>  <unk>  is recurrent nausea, vomiting, and cramping abdominal pain that sometimes occurs due to prolonged, high-dose cannabis use. These symptoms may be relieved temporarily by taking a hot shower or bath. Complications may include kidney failure and electrolyte problems, and the condition can be fatal if not properly managed. Weekly cannabis use is generally required for the syndrome to occur; synthetic<unk> s can also cause<unk> . The underlying mechanism is unclear, with several possibilities proposed. Diagnosis is based on the symptoms, as well as the history of cannabis use (including a urine screen test if necessary). The condition is typically present for some time before the diagnosis is made. Another condition that presents similarly is cyclic vomiting syndrome (CVS). The only known effective treatment for<unk>  is to stop using cannabis. Two weeks (or possibly more) may be required to see a benefit. The primary differentiation between<unk>  and CVS is that cessation of cannabis use only relieves<unk> . Treatments during an episode of vomiting are generally supportive in nature (e.g., hydration). There is tentative evidence for the use of capsaicin cream on the abdomen during an acute episode. The syndrome was first described in 2004, and simplified diagnostic criteria were published in 2009.
