No, cannabinoid hyperemesis syndrome (CHS) and cyclic vomiting syndrome (CSV) are different conditions that cause similar symptoms. CVS is a disorder that causes episodes of nausea and vomiting that are unrelated to cannabis use. CVS usually affects children and adolescents, while CHS usually affects adults who use cannabis chronically. The main difference between CHS and CVS is that stopping cannabis use only relieves CHS, while CVS may require other treatments.
