In recent years, a peculiar condition linked to marijuana use has been increasingly reported in emergency rooms. Known as Cannabis Hyperemesis Syndrome (CHS), this condition is characterized by uncontrollable vomiting and has been puzzling both doctors and patients. Let’s delve into the science behind this syndrome and explore its implications on marijuana legalization worldwide.
CHS was first identified in the early 2000s when a few marijuana users in Australia experienced severe vomiting episodes. Since then, the number of cases has surged. For instance, in Ontario, Canada, there was a 13-fold increase in emergency room visits due to cannabis-induced vomiting between 2014 and 2021. Similarly, in Colorado, where marijuana is legal, there was a 29% rise in such cases from 2014 to 2019. A notable symptom observed in these patients is “scromiting,” a term describing the simultaneous occurrence of screaming and vomiting.
To understand why marijuana causes this condition, we need to look at the endocannabinoid system, a crucial neurobiological network in our bodies. This system helps maintain balance, or homeostasis, by regulating stress, appetite, mood, and nausea. It operates through natural neurotransmitters called cannabinoids, which interact with receptors like the CB1 receptor in the brain.
Marijuana contains compounds that mimic these natural cannabinoids. When consumed, it introduces a surge of cannabinoids, including THC, the psychoactive component that induces a “high.” While this can enhance perception and imagination, it can also disrupt the endocannabinoid system’s regulation of nausea and anxiety, especially in heavy users. Researchers believe that this overstimulation leads to CHS.
Physiologically, cannabis affects serotonin levels in brain regions controlling nausea and vomiting. While low doses can alleviate nausea in chemotherapy patients, excessive and prolonged use can overstimulate CB1 receptors, causing the system to malfunction. This results in an inability to control nausea and vomiting, hallmark symptoms of CHS.
Moreover, marijuana influences appetite by activating brain areas that trigger hunger, often leading to “the munchies.” However, chronic use can eventually suppress appetite, potentially leading to vomiting.
The severity of CHS varies based on factors like diet, age, body size, and marijuana consumption patterns. Studies indicate that individuals with CHS typically consume around 4 grams of marijuana daily, equivalent to about eight large joints.
Research primarily from regions where marijuana is legal, such as Alberta, shows a significant increase in CHS cases. For example, the incidence rose from 15 to 32 per 100,000 people between 2018 and 2020, with higher rates among 16 to 24-year-olds.
As CHS cases continue to rise, the question arises: will this affect marijuana legalization? In Canada, where marijuana is legal, so are alcohol and cigarettes. Despite alcohol being responsible for more deaths and the possibility of overdosing on it, marijuana remains less lethal. Researchers currently do not foresee a halt in legalization, but awareness of CHS is crucial.
Maintaining homeostasis is vital, and the endocannabinoid system plays a key role. Excessive marijuana use can disrupt sleep, mood, anxiety, and vomiting control. As a marijuana consumer, understanding these effects is essential for informed decision-making. More research and funding are needed to better understand this emerging condition.

**Sanitized Transcript:**
Uncontrollable vomiting due to marijuana use is on the rise, and a mysterious cannabis-related condition is turning up in emergency rooms. People are getting sick from a new disease caused by cannabis. Today, we’re going to explain the science behind what is going on and whether or not it will impact marijuana legalization around the world.
The disease is called Cannabis Hyperemesis Syndrome, and it was first described in the early 2000s when a handful of marijuana users ended up in Australian emergency rooms with uncontrollable vomiting. Since then, the disease has been increasing. For example, in Ontario, Canada, there was a 13-fold increase in people ending up in the ER from cannabis-induced vomiting syndrome between January 2014 and January 2021. In Colorado, where marijuana is legalized, there was a 29% increase in vomiting-related emergency room visits from 2014 to 2019. During this time, doctors started to notice that these cannabis users exhibited a behavior known as “scromiting,” which is a combination of screaming and vomiting. It was understood that these users kept vomiting even when there was little food left in their stomachs, leading to this unusual noise.
So, what is happening here? Why is marijuana making some people sick? It has to do with the endocannabinoid system, a widespread neurobiological system in your body that helps maintain homeostasis, or balance. When you become stressed, it helps relieve that stress. If you swallow a toxin, the endocannabinoid system will help you vomit it back up, all to keep you at a healthy baseline.
The endocannabinoid system is controlled by natural neurotransmitters in your body called cannabinoids, which act on receptors such as the CB1 receptor in your brain. Marijuana contains molecules that mimic these cannabinoids. Without marijuana, cannabinoids circulate at lower quantities in your body, but when you ingest marijuana, you create an influx of cannabinoids, such as the psychoactive component THC, which resembles a natural neurotransmitter called anandamide. This creates neuronal activity in certain parts of your brain that make you feel high, causing thoughts, imagination, and perception to magnify. However, since the endocannabinoid system affects other aspects of homeostasis, such as sleep, mood, appetite, anxiety, and nausea, these can also be impacted.
Researchers believe that the overstimulation of the endocannabinoid system in heavy marijuana users leads to a disruption in the body’s intrinsic control of nausea, anxiety, and vomiting, resulting in Cannabis Hyperemesis Syndrome.
Physiologically, cannabis consumption modulates serotonin in areas of the brain that control nausea and vomiting. At low doses, it can be therapeutic for patients undergoing chemotherapy to relieve nausea. However, in large amounts over long periods, cannabis can overstimulate CB1 receptors, causing the endocannabinoid system to malfunction. This can lead to difficulties in shutting off nausea or returning to a baseline state when stressed or anxious, resulting in the uncontrollable vomiting associated with this syndrome.
Additionally, marijuana can affect your stomach. It is known to increase activity in parts of the brain that promote hunger, leading to the phenomenon known as “the munchies.” However, excessive cannabis consumption can lead to a decrease in appetite, which may eventually lead to vomiting.
The severity of this condition depends on various factors, including diet, age, body size, and most importantly, how long and how often marijuana is consumed. One study found that individuals with Cannabis Hyperemesis Syndrome consumed an average of 4 grams of marijuana per day, which is roughly equivalent to eight large joints.
Most of the research on this condition is coming from places where marijuana is legalized. In Alberta, the number of cannabis-induced syndrome patients in the ER increased from 15 per 100,000 people in 2018 to 32 per 100,000 in 2020. Notably, among 16 to 24-year-olds, the incidence is even higher, with 600 out of 100,000 affected.
If these trends continue, we may hear more about this disease in the future. Currently, the only known way to alleviate it is to reduce or completely stop marijuana consumption, which can be quite challenging.
Does this mean that legalization will be halted? It’s uncertain. In Canada, where marijuana is legalized, so are alcohol and cigarettes. Alcohol, for example, is responsible for more deaths than marijuana, and while you can overdose on alcohol, you cannot overdose on marijuana. Researchers currently do not believe that legalization will be stopped, but we need to be aware of this new disease.
Maintaining homeostasis in your body is important, and the endocannabinoid system plays a crucial role. Consuming excessive amounts of marijuana can disrupt your body’s ability to control sleep, mood, anxiety, and vomiting. As someone who consumes marijuana, I find this information fascinating and important for making informed decisions. We need more research and funding on this topic, as it is a new disease and the information is still emerging.
