Cannabinoid hyperemesis syndrome (CHS) is a condition that sometimes develops due to the use of marijuana. The syndrome causes repeated and severe vomiting and nausea.
It is important for people with CHS to stop using marijuana because this will resolve their nausea and vomiting. Preventing dehydration and stopping nausea and vomiting are the treatment goals during the hyperemesis stage of the condition.
When people with CHS stop using marijuana, their symptoms of nausea and vomiting usually disappear. Nausea and vomiting tend to return if they start using marijuana again.
