Imagine being hit with waves of nausea so intense they leave you screaming in agony. For some chronic cannabis users, this isn't just a nightmare – it's the reality of Cannabis Hyperemesis Syndrome (CHS), and trust me, the 'munchies' are not the biggest problem here. This condition is sending people to the ER in droves, and it's often a baffling, recurring nightmare. Over the last decade, emergency rooms have witnessed a disturbing rise in cases of regular cannabis users arriving with sudden, debilitating episodes of nausea and abdominal pain. The truly frightening part? Many of these individuals endure these agonizing attacks three or four times each year, leaving both the patients and their healthcare providers completely perplexed.
So, what exactly is CHS?
Cannabis Hyperemesis Syndrome (CHS) is a debilitating disorder characterized by relentless nausea, severe abdominal pain, and intense vomiting that can occur multiple times an hour, according to the Cleveland Clinic. Imagine your body betraying you with wave after wave of sickness. Symptoms typically begin within 24 hours of cannabis use and can persist for days. The severity of these episodes has led ER staff to coin a rather unsettling term: "scromiting," a chilling blend of screaming and vomiting, perfectly capturing the intense suffering involved.
But here's where it gets controversial... Many people still believe cannabis is a harmless substance, leading to dismissal of these symptoms or attributing them to other causes. Is it possible that the increasing potency of cannabis products is playing a significant role in this rise of CHS cases?
A Tough Puzzle to Solve
Despite its growing prevalence, many doctors remain unfamiliar with CHS. The syndrome was only recently formally defined, making it challenging to differentiate from other medical conditions like food poisoning or the stomach flu. Dr. Beatriz Carlini, a research associate professor at the University of Washington (UW) School of Medicine, who studies the adverse health effects of cannabis use, stated that individuals often experience multiple visits to the emergency department before receiving a correct diagnosis, incurring significant costs each time. It's like searching for a needle in a haystack when doctors aren't even aware of the haystack's existence! But even after a diagnosis is made, CHS can be notoriously difficult to treat.
Currently, there are no FDA-approved therapies specifically for CHS. Standard anti-nausea medications often prove ineffective, according to Dr. Chris Buresh, an emergency medicine specialist with UW Medicine and Seattle Children's Hospital. This often forces clinicians to resort to second- and third-line treatment options, including Haldol, a medication more commonly used for psychotic episodes. Yes, you read that right – a drug typically reserved for severe mental health conditions is sometimes needed to combat the effects of CHS.
Some patients find limited relief by applying capsaicin cream to their abdomens. This creates a warming sensation that can temporarily ease the discomfort. Hot baths and showers also often help to alleviate symptoms, with many patients driven to bathe for hours each day seeking solace from their pain. Dr. Buresh notes that one of the key telltale signs for him is when a patient says they feel better with a hot shower, adding, "Patients describe going through all the hot water in their house."
The Road to Recovery: A Difficult Journey
Even after the symptoms subside, long-term recovery can be a challenging endeavor. Because the syndrome strikes intermittently, some cannabis users mistakenly believe that a recent episode was unrelated to their cannabis use and continue to use, only to become severely ill again. This cyclical pattern can be incredibly frustrating and disheartening. For those who accept the diagnosis and attempt to quit, addiction often poses a major obstacle, prolonging the cycle of illness, as Dr. Carlini explains. Currently, the only definitive cure for CHS is complete cessation of cannabis use. This may sound simple, but for individuals struggling with addiction, it can be an immense challenge.
Who is at Risk? From Teens to Long-Time Users
Scientists are still working to unravel the exact cause of CHS. The leading theory suggests that long-term overstimulation of receptors in the endocannabinoid system may disrupt the body's natural control of nausea and vomiting, according to the Cleveland Clinic. However, why this affects certain cannabis users and not others remains a mystery. Dr. Buresh raises some crucial questions: "We don't know if it's related to the greater general availability of cannabis, the higher THC potency of some products, or something else entirely." He adds, "It seems like there's a threshold when people can become vulnerable to this condition, and that threshold is different for everyone. Even using in small amounts can make these people start throwing up." And this is the part most people miss...
A study published earlier this year by researchers at George Washington University surveyed 1,052 individuals with CHS in an effort to better understand the risk factors. The study revealed that starting cannabis use earlier in life was associated with a higher likelihood of future ER visits for hyperemesis symptoms. Daily use and prolonged consumption were also common, with 44% reporting regular use for more than five years before the syndrome manifested.
However, CHS is not solely an adult problem. Research indicates that emergency department visits among adolescents in the US have increased more than tenfold from 2016 to 2023. Notably, while overall rates were higher in states with legal recreational cannabis, the fastest year-over-year increases in the number of adolescent CHS cases at hospitals occurred in states where casual cannabis use is still illegal. This might suggest that increased awareness and reporting is occurring in legalized states, or perhaps that black market products are more likely to cause CHS. What do you think?
Gaining Much-Needed Attention
On October 1st, the World Health Organization formally recognized cannabis hyperemesis syndrome, adding an official diagnosis code to its manual. The CDC has also incorporated the new code into US diagnostic systems. Experts believe that this update offers several benefits, including providing researchers with a clearer picture of the prevalence of CHS. Furthermore, having the code appear in a patient's medical record helps providers identify repeat episodes during future visits. Dr. Carlini emphasizes that "A new code for cannabis hyperemesis syndrome will supply important hard evidence on cannabis-adverse events, which physicians tell us is a growing problem."
