### What is Cannabinoid Hyperemesis Syndrome (CHS)? Cannabinoid hyperemesis syndrome (CHS) is a condition that can occur in people who use marijuana regularly over a long period. It causes repeated episodes of severe nausea, vomiting, and stomach pain. ### Symptoms of CHS 1. **Nausea and Vomiting**: Persistent and severe nausea and vomiting are the most common symptoms. 2. **Stomach Pain**: Many people experience intense stomach pain. 3. **Dehydration**: Due to excessive vomiting, dehydration can occur, leading to dizziness, confusion, and a rapid heartbeat. 4. **Hot Showers**: People with CHS often take very hot showers or baths to relieve symptoms. 5. **Scromiting**: A combination of screaming and vomiting due to intense pain. ### Phases of CHS CHS symptoms usually occur in three phases: 1. **Prodromal Phase**: Characterized by nausea and abdominal discomfort without vomiting. 2. **Hyperemetic Phase**: Intense and frequent vomiting, lasting 24-48 hours. 3. **Recovery Phase**: Symptoms improve after stopping marijuana use. ### Treatment The only effective treatment for CHS is to stop using marijuana. Over-the-counter medications and hot showers can help manage symptoms during the recovery phase. If symptoms are severe, hospitalization may be necessary for treatments like IV fluids and anti-nausea medications. ### Prevention and Recovery The best way to prevent CHS is to avoid or quit marijuana use. If you need help quitting, consult your doctor or contact the Substance Abuse and Mental Health Services Administration (SAMHSA) National Helpline at 800-662-HELP (4357).
