Research shows that the more THC a person consumes, the higher the health risks. In the short term, frequent use of products with high THC concentration increases the risk of experiencing anxiety, paranoia, and panic. Regular use of these products increases the risk of developing cannabis use disorder, cannabis hyperemesis syndrome, and of experiencing psychotic symptoms. Cannabis-related emergency department visits for acute psychiatric symptoms and cannabis hyperemesis syndrome have been on the rise.
More information about cannabis use disorder and other health risks can be found in the “Cannabis and Health ” section.
What is cannabis hyperemesis syndrome (CHS)?
CHS is a condition first identified in 2009 and associated with long-term, regular cannabis use. Symptoms include nausea and recurring vomiting that is not linked to other symptoms, such as fever; although weight loss and dehydration may result. Because of how rare CHS was in the past, it may go unrecognized, undiagnosed, or misdiagnosed (frequently as cyclical vomiting disorder). Temporary relief is often found with hot showers combined with the topical application of capsaicin oil. Symptoms will go away with complete abstinence from cannabis use. A return to cannabis use may result in the return of CHS.
