Marijuana and Uncontrolled Vomiting

Marijuana was considered safe in the past, but now marijuana and uncontrolled vomiting suddenly make the news. Recently there also were reports of marijuana causing heart attacks and schizophrenia.

Abdominal pain with cannabis hyperemesis syndrome

Cannabis hyperemesis syndrome or cannabinoid hyperemesis syndrome (CHS) is a relatively new disease entity. It occurs in people who use marijuana daily for several years. But people affected by this condition often do not realize that it is an overdose of marijuana that brings on the nausea and vomiting of CHS. When they started marijuana use, they may have used intermittent doses of marijuana to treat nausea and vomiting. In intermittent doses marijuana may have been helpful, however constant use is a different story! During several years of use of marijuana, patients never had abdominal pains or vomiting, until one day CHS started.

Possible mechanisms regarding marijuana and uncontrolled vomiting

The body has its own endocannabinoid system with cannabinoid receptors that are distributed throughout the body. There are two cannabinoid receptors, CB1 and CB2. In the central nervous system, there are mainly CB1 receptors, in the rest of the body CB2. It appears that stimulation with intermittent small doses of marijuana suppresses nausea and vomiting in the hypothalamus area. However, constant stimulation of CB2 receptors in the gut with higher doses of marijuana are the cause of CHS. When a person develops cannabis hyperemesis syndrome, the only permanent cure is to stop marijuana use completely. This eliminates the CB2 receptor stimulation and allows the body to heal the gut. Researcher believe that Tetrahydrocannabinol, or THC is more powerful than the endocannabinoids. THC overwhelms the CB1 and CB2 receptors. When people who were cured of CHS restarted marijuana, their symptoms of nausea and abdominal pain returned.

In some people hot bath and hot showers help uncontrolled vomiting

Researchers noted that people reported how sometimes having a hot shower or a hot bath stopped the vomiting. The hypothalamus controls both body temperature and vomiting. A hot bath may send a signal to the hypothalamus, which interrupts the vomiting for a period of time. But with continued use of marijuana the vomiting reoccurs.

Increased strength of marihuana preparations

Dr. Wang, an associate professor of pediatrics at the University of Colorado Anschutz Medical Campus in Aurora, Colorado noted: “It’s been well documented that the amount of THC that now comes in cannabis is increasing substantially. In the ’90s the average was like 4% or 5%. Now in Colorado, it’s anywhere from 15% to 20%.” This means that THC causes more and more toxicity in patients.

In Colorado medical marijuana was legal since 2009 and recreational marijuana was legal since 2014. Dr. Wang researched the cannabis hyperemesis syndrome in Colorado. He found over 800,000 cases of vomiting in Colorado between 2013 and 2018. This was an increase of 29% from the time before marijuana became legal.

Symptoms of cannabis hyperemesis syndrome

The 5 most common symptoms of cannabis hyperemesis syndrome are continuous nausea, repeated vomiting, abdominal pain, weight loss because of decreased food intake and dehydration from fluid loss. Many people have several showers a day because it diminishes their nausea.

Three phases of cannabis hyperemesis syndrome

The cannabis hyperemesis syndrome often presents in 3 stages: the prodromal phase, the hyper emetic phase, and the recovery phase.

During the prodromal phase symptoms consist of nausea and abdominal pain early in the morning. The eating pattern is still normal in this phase. Some people increase their marijuana consumption as they hope to treat the nausea this way. This phase can last for months or years.

During the hyper emetic phase all of the 5 symptoms mentioned above can occur. This phase often continues until the patient gives up all marijuana consumption. This is when the recovery phase starts.

In the recovery phase the patient returns to a normal eating pattern. All of the symptoms gradually disappear. This phase lasts between days to months. But if the patient starts marijuana again, the symptoms return very quickly.

Treatment of cannabis hyperemesis syndrome

Patients who have severe vomiting require treatment in a hospital. The doctor starts intravenous fluids to treat dehydration. Some medicine to stop vomiting helps in the beginning. The physician must convince the patient to completely stop marijuana use, which helps to treat nausea and abdominal pain. Antacid medication like proton-pump inhibitors is useful to treat stomach lining inflammation. Frequent hot showers help to tone down nausea and vomiting. Hot showers seem to work via the hypothalamic brain center, which is responsible both for nausea/vomiting and heat perception. The physician may prescribe small amounts of benzodiazepams to treat anxiety.

By avoiding marijuana in any form THC, which is a powerful stimulus for CB1 and CB2 receptors gets washed out of the system. This allows the endocannabinoid system to rebalance itself. As long as the patient stays away from marijuana there is usually a complete recovery.

Conclusion

Since marijuana is legal in many jurisdictions the cannabis hyperemesis syndrome (CHS) occurs more and more often. Emergency teams at hospitals are kept busy treating these types of patients. It appears that CHS develops in patients who use marijuana regularly and use it in higher concentrations. Nausea and vomiting are the most common symptoms. Some patients can cope for a period of time by taking frequent hot showers. But eventually this home remedy does no longer work. A brief hospital stay may help the patient to recover from this syndrome. The patient needs to stay away from marijuana products to recover from CHS completely, otherwise there will be a relapse.

Marijuana Causes Schizophrenia and Heart Attacks

Two new studies showed that marijuana causes schizophrenia and heart stacks. Marijuana use has been increasing significantly in the general population since the 1990’s. Initially many believed that marijuana would be harmless. But increasingly there are medical publications showing the opposite.

In the following I present data how the use of marijuana causes these two documented side effects, heart attacks and schizophrenia.

Schizophrenia increased since the 1990’s

A July 21, 2021 study from Denmark included all people of Denmark who were older than age 16 from January 1, 1972 to Dec. 31, 2016. The number of participants were 3 ,595 ,910 women (50.0%) and 3 ,590 ,924 men (50.0%). The total number of individuals in the study were 7,186 ,834.

Here are the figures of the percentages of cannabis related schizophrenia cases in Denmark according to the study:

  • 1995: 2% of all schizophrenia cases related to cannabis use in Denmark
  • 2000: 4% of schizophrenia cases due to cannabis use
  • 2010: 8% of all schizophrenia cases from cannabis use

The researchers found that the risk of coming down with schizophrenia heightens with increased cannabis use. Heavy users are more likely to develop schizophrenia than light users.

Cannabis use disorder

One subgroup of cannabis users are people with a cannabis use disorder. They use cannabis, but they become tolerant to it. This requires a higher dose of cannabis to achieve satisfaction. But they are unable to reduce cannabis. They spend more and more time to obtain cannabis, use it and recover from the effect. They give up other activities in favor or cannabis and they continue the use despite negative consequences. Researchers found that this group of individuals had the highest risk to develop schizophrenia. The authors of the Danish study found that patients with cannabis use disorder over the past 2 decades have increased their risk for developing schizophrenia by 3- to 4-fold. They feel it is because of the increase in use and the increase in potency of cannabis.

Heart attacks increased with cannabis use

A Canadian study assessed a cross-sectional study of 2017 and 2018.

The study in question was the American Behavioral Risk Factor Surveillance System survey of US adults. The authors zeroed into young adults (aged 18–44 yr.) with recent cannabis use and a history of a heart attack. Among 33,173 young adults there were 4,610 respondents with recent cannabis use (17.5%). 61 respondents among the recent cannabis users reported that they had a heart attack, which is 1.2%. In comparison non-cannabis users had a heart attack rate of only 0.8%. The adjusted odds ratio for cannabis users compared to non-users was 2.07. This means that the probability of getting a heart attack when using cannabis was 2.07-fold higher when compared to non-users. Also, the investigators found that a history of a heart attack had a probability of being due to cannabis use with a probability of 2.31-fold.

Cannabinoid receptors

Researchers found endogenous cannabinoids in the brain that function as messenger molecules. They need to activate their targets, the cannabinoid receptors, called CB1 and CB2. CB1 receptors are found mainly in the central nervous system. CB2 receptors are located mainly in the immune system. Reproductive organs have their own cannabinoid receptors. The lining of the uterus contains only CB1 receptors. Ovaries and testicles both use CB1 and CB2 receptors. Tetrahydrocannabinol (THC) from smoking or ingesting marijuana is the main psychoactive compound in cannabis. It stimulates these cannabinoid receptors also. But compared to the body’s own cannabinoids THC is much stronger. This leads to more pronounced effects that concern many physicians.

The overwhelming response of the cannabinoid receptors to THC leads to a blunting of the signals of the body’s own cannabinoids. This causes a breakdown in communication between neurons and body cells.

Conclusion re. marijuana causes schizophrenia and heart attacks

Legislators in Canada and many of the states in the US legalized the use of marijuana. As a result, the cannabis use in the younger age group of adults (between 18 to 44 years) has increased significantly. This means that more and more people are exposed to THC from cannabis, which overstimulates the body’s own endocannabinoid system. As explained this leads to a breakdown of communication between neurons and body cells. In time diseases like heart attacks and schizophrenia can develop, a fact overlooked by the media and the public. The overuse of marijuana leads to more than a 2-fold risk to get a heart attack and a 3- to 4-fold risk of coming down with schizophrenia. These are the facts right now. But with further increased use of cannabis researchers will likely find many other diseases that THC can trigger.
