Treating and Preventing Cannabinoid Hyperemesis Syndrome (CHS)
Cannabis is now legal in Canada and can cause serious side effects in some people. Individuals who have cannabinoid hyperemesis syndrome (CHS) experience ongoing nausea and stomach pain that may result in frequent vomiting and weight loss. Using cannabis at least once a week for more than a year is known to increase the risk of CHS.
