• Cannabinoid Hyperemesis Syndrome (CHS) is a condition that can happen in some people who use cannabis over time.
• It causes repeated episodes of severe nausea, vomiting, and stomach pain.
• Many people don’t realize what it is at first and are often misdiagnosed.

Common Symptoms

• Severe nausea and vomiting
• Stomach pain or cramping
• Relief from hot showers or baths (very common sign)
• Loss of appetite
• Dehydration from repeated vomiting
• Cycles (symptoms come and go)

The Pattern of CHS

• Early stage: mild nausea, occasional discomfort
• Active stage: frequent vomiting episodes, ER visits often
• Recovery stage: symptoms improve after stopping cannabis use

Why CHS is often misunderstood? 

• It is still widely unknown in the medical community and public
• Many people are diagnosed with food poisoning, stomach viruses, or anxiety first
• This delay can make symptoms worse over time

What Helps?

• The only known way to stop CHS symptoms is to stop cannabis use
• During episodes, people often need medical care for dehydration
• Hot showers may temporarily relieve symptoms, but do not fix the condition. 

Why awareness matters? 

• Earlier recognition can reduce suffering and ER visits
• Education helps prevent misdiagnosis
• No one should go through it alone or uninformed

Emotional impact 

• CHS can feel isolating and overwhelming
• Many people feel dismissed or not believed
• Families are often confused and scared watching it happen

You Are Not Alone
