The troubling rise in emergency room visits linked to a mysterious marijuana-induced illness has reached concerning levels, doubling since 2017. The condition, known as Cannabinoid Hyperemesis Syndrome (CHS), can lead to debilitating symptoms such as persistent vomiting, severe nausea, and intense abdominal pain, enduring for weeks and potentially resulting in life-threatening dehydration, seizures, and kidney failure.

Many affected individuals find a hot shower to be the only respite at home, while hospitals typically administer anti-nausea medications and intravenous fluids to manage these extreme symptoms.

A recent case highlights the severe consequences of this syndrome. In June, a harrowing study detailed the story of a 22-year-old Canadian woman, who tragically passed away from heart complications after years of cannabis use. Despite visiting her physician multiple times for uncontrollable nausea and vomiting, it was only in the aftermath of dehydration and nutrient loss linked to CHS that her health deteriorated fatally.

Dr. Maria Isabel Angulo from the University of Illinois has provided alarming statistics, estimating that CHS now impacts around 2.75 million Americans annually, with the highest incidence among men aged 16 to 34. The surge in cases appears to be fueled by two significant factors: the increasing potency of marijuana and its growing legalization across the United States.

Decades of cultivation advancements have resulted in a striking rise in THC (tetrahydrocannabinol) concentration in cannabis. According to data from Yale School of Medicine, THC content skyrocketed from an average of 4% in 1995 to approximately 17% in 2017, and today, it can even exceed 35%. "The cannabis available now is much more potent than what was offered 30 years ago," noted Dr. Deepak Cyril D'Souza, a psychiatrist at Yale.

Contrary to some misconceptions, recent studies indicate that CHS is not caused by marijuana contaminated with other substances. Instead, the principal factor appears to be the frequency and quantity of THC consumption. Research from the Department of Medicine at the University of Calgary used hospital data and patient surveys to underscore this alarming trend.

Interestingly, there are approximately 55 million marijuana users in the USA, according to the National Center for Drug Abuse, suggesting that as many as 5% of weed smokers may experience CHS. Daily users, particularly those who started consuming marijuana before age 16, are at a significantly increased risk.

The scientific community continues to explore the underlying mechanisms leading to this extreme reaction. The Cleveland Clinic's leading theory proposes that frequent marijuana use alters the endocannabinoid system—a crucial network of chemicals and proteins that regulate pain response, appetite, stress management, and gastrointestinal movement. Chronic stimulation of this system could disrupt its balance, triggering extreme cycles of vomiting.

Doctors diagnose CHS patients by evaluating their symptoms and history, determining susceptibility based on recurrent vomiting episodes and their cannabis use. However, stopping marijuana abruptly can lead to withdrawal symptoms, complicating recovery.

For those hospitalized, treatment typically includes anti-nausea medications and rehydration therapies, with some cases requiring psychotic symptom management. Following recovery, physicians often prescribe antidepressants and strongly advise against future cannabis consumption.

With the rising prevalence of CHS, it is crucial for cannabis users to be informed about the risks and potential health consequences associated with high-THC marijuana. If you or someone you know experiences severe vomiting or other symptoms after using cannabis, seeking medical attention promptly could be life-saving.
