What is Cannabinoid Hyperemesis Syndrome?


Cannabinoid hyperemesis syndrome (CHS) is a condition that results in continuous and severe bouts of vomiting. It is rare and only occurs in daily long-term users of marijuana.


Marijuana contains many active substances. These include THC and related chemicals. These substances bind to molecules found in the brain. That causes the drug “high” and other effects that users feel.


Your digestive tract also has a number of molecules that bind to THC and related substances. This is how marijuana also affects the digestive tract. For example, the drug can change the time and the process through which you empty your stomach. It also affects the esophageal tract. That’s the tight band of muscle that opens and closes to let food from the esophagus into the stomach. Long-term marijuana use can change the way the affected molecules respond and lead to the symptoms of Cannabinoid Hyperemesis Syndrome (CHS).



What causes Cannabinoid Hyperemesis Syndrome?


Marijuana has a very intricate effect on your body. Experts are on an ongoing study to determine the causes of CHS in people.

It is funny how the effect on your brain is entirely opposite. It helps prevent nausea and vomiting. The drug is also good at stopping such symptoms in people having chemotherapy.


However, when it comes to the digestive tract, marijuana seems to have the opposite effect. It actually makes you more likely to have nausea and vomiting. During the initial use of the drug, the brain signals may be more important. That may lead to anti-nausea effects at first. The prolonged use and addiction to the drug can make certain receptors in the brain to stop responding to the drug in the same way. That may cause repeated bouts of vomiting found in people with CHS.
