This is an excellent study that determined the prevalence of cannabinoid hyperemesis syndrome among patients in an emergency department of a public hospital to be 32.9% at a 95% level of confidence. I found it interesting the condition was most common in patients who were between the ages of 18-29. I learned of CHS through this study and remembered a forum thread where someone asked why they were experiencing stomach problems and pain when smoking cannabis. The symptoms were said to be relieved with hot showers and cessation of smoking.
