Cannabinoid hyperemesis syndrome (CHS) is characterized by repeated and extreme vomiting that results from long-term, excessive cannabis use. Although rare, the condition has become more prevalent as more states legalize medical marijuana.
According to a 2015 study published in the journal Academic Emergency Medicine, emergency cases of CHS in two Colorado hospitals have nearly doubled since 2009.
A number of people with CHS undoubtedly remain undiagnosed. This is because many doctors are unaware of the syndrome and because individuals rarely want to admit to using marijuana, an illegal substance in the United States.
Chronic marijuana use can lead to cannabinoid hyperemesis syndrome. The disorder typically occurs in heavy marijuana users rather than those who use the drug casually. But research associated with CHS is limited.
The disorder confuses many medical experts because the primary ingredient in marijuana, THC, has anti-nausea effects. In fact, the cannabinoid medications dronabinol and nabilone have been approved by the Food and Drug Administration to treat nausea caused by chemotherapy.
But long-term marijuana use can produce contradictory effects. And repeated cannabis use can trigger bouts of nausea and vomiting in some people.
Research on the syndrome is ongoing. According to St. Luke’s Health System, experts are still trying to figure out why CHS occurs in some heavy marijuana users and not others. Risk factors for the disorder are unknown.
The condition is not associated with any particular method of marijuana use, but it may be becoming more prevalent because marijuana is more potent than ever.
Some theorize that using cannabis strains rich in THC for an extended period of time increases a person’s risk for the disorder. In states where recreational marijuana is legal, some brands of marijuana contain up to 30 percent THC.
People with CHS describe their symptoms as overwhelming and incapacitating, according to a 2011 study published in the journal Current Drug Abuse Reviews.
Symptoms of cannabinoid hyperemesis syndrome often include:
The condition can lead to dehydration or kidney failure caused by excessive vomiting. In extreme cases, brain swelling, muscle spasms, heart rhythm abnormalities, shock or seizures can occur. CHS symptoms often subside within two days, although some effects persist for several weeks.
The most intense symptoms of CHS take time to occur. People with the disorder often feel cyclic periods of nausea for months or years. When vomiting occurs, it can last for up to a week. But most symptoms subside in a couple days if no marijuana is used.
CHS comprises three phases: prodromal, hyperemetic and recovery.
The prodromal phase can last several years. This stage is characterized by abdominal discomfort, early morning nausea and a fear of vomiting. During this time, people maintain normal eating patterns and continue using marijuana for its perceived anti-nausea effects.
In the hyperemetic phase, individuals experience mild abdominal pain, dehydration, weight loss and intense nausea and vomiting. The vomiting occurs without warning up to five times per hour. This phase generally lasts about 48 hours.
The recovery phase occurs when individuals cease marijuana use. They then regain weight and resume normal bathing and eating habits. This stage can last for days, weeks or months if no marijuana is used.
It is important to seek medical attention if you experience severe vomiting, dehydration or weight loss caused by marijuana use. Medical experts can ease distressing symptoms and expedite the recovery stage.
Hot bathing has been shown to relieve abdominal pain, nausea and vomiting in people with cannabinoid hyperemesis syndrome. A 2017 report published in the journal German Medical Science showed that 60 percent of people with the disorder reported that hot bathing reduced CHS symptoms.
Treatment for cannabinoid hyperemesis syndrome often involves supportive therapy with intravenous fluids and anti-emetic medications. During the hyperemetic phase, IV fluids might include lorazepam, proton pump inhibitors, and sodium chloride solution.
The most effective way to prevent cannabinoid hyperemesis syndrome is to reduce or avoid marijuana use. However, this may be difficult for individuals with a marijuana addiction. People addicted to cannabis compulsively seek the drug despite the consequences.
People struggling with cannabinoid hyperemesis syndrome may have a severe marijuana use disorder. If you think cannabis use is affecting your life, contact a rehab center for marijuana abuse. These facilities can assist you in overcoming substance abuse and living a healthy, drug-free life.
