Cannabinoid Hyperemesis Syndrome-A Survey-Based Approach to Understanding Symptoms and Cannabis Use Patterns

Our findings suggest that CHS is most associated with long-term, frequent use of inhaled delta-9-tetrahydrocannabinol (Δ9-THC) dominant cannabis. The acquisition source of cannabis products did not affect the syndrome presentation. Although many different cannabis consumption methods were represented, smoking and vape cartridges were the most commonly reported. The use of vape cartridges was associated with a shorter time to the development of CHS symptoms. Increased awareness of these patterns could improve the early recognition and management of CHS.
