The ClearCHS Foundation is a free, independent educational resource dedicated to cannabinoid-hyperemesis-syndrome (CHS).

Key Resources

• Self-Assessment: A free, anonymous 3-minute tool evaluating symptoms and usage patterns.
• ER Guidance: Support for active hyperemesis episodes, suggesting patients discuss topical capsaicin cream, IV fluids, haloperidol, or benzodiazepines with clinicians.
• Recovery Hub: Practical guides covering the first 48 hours, withdrawal, and clinical communication.

CHS Insights

• Symptoms: Severe nausea, vomiting, abdominal pain, and compulsive hot showering.
• Mechanism: Long-term cannabis use (typically 1+ years) alters how gut receptors respond to THC.
• Clinical Context: CHS emergency department visits doubled between 2017 and 2021. It is frequently misdiagnosed as cyclic vomiting syndrome due to symptom overlap.
