Marijuana: Potent Laxative Or Not?

Marijuana has been used medicinally for thousands of years, and its positive effects on health conditions and treatment side effects are becoming more widely recognised. While it is often associated with getting high, marijuana has been shown to have a positive impact on digestive issues, including constipation. Research has found that marijuana use is associated with a decreased likelihood of constipation, with one study showing a 30% decrease in prevalence among recent users compared to non-users. This may be due to the impact of marijuana on mucus production in the digestive system, which helps to soften stool. In addition, marijuana's influence on the parasympathetic nervous system, or the rest and digest system, can help the body relax and promote bowel movements. However, it is important to note that marijuana can also lead to digestive problems, especially with heavy and regular use over several years.

Marijuana can reduce the risk of constipation

Marijuana has been used medicinally for thousands of years, and modern science is now confirming its effectiveness in treating various health conditions and their side effects, including constipation. Research shows that marijuana can be an effective treatment for constipation, although it is important to note that it can also affect the digestive system in both positive and negative ways.

How Marijuana Can Help with Constipation

Marijuana can be used as a natural laxative to treat constipation. Laxatives work by stimulating the movement of fecal matter through the bowel and softening and loosening hard-to-pass feces. Marijuana, specifically the cannabinoid THC, can help relax the smooth muscles in the intestinal wall, making it easier for the intestines to pass bulk bowel movements. This is due to the influence of THC on the cannabinoid receptors, which increases digestive motility. Additionally, marijuana appears to alter the production of mucus in the digestive system, and this mucus helps to soften stool and make it more watery. This process is guided by a natural endocannabinoid called 2-AG, which is produced by the body and regulates digestive behavior.

The Parasympathetic Nervous System

Another way that marijuana helps with constipation is by activating the parasympathetic nervous system, also known as the "rest and digest" system. This system helps the body to relax, especially after periods of trauma or stress. The parasympathetic state is important for defecation, as it is difficult to have a smooth bowel movement while in a fight-or-flight state, which is managed by the sympathetic nervous system. Endocannabinoids, including 2-AG, help keep the body in balance by regulating the sympathetic and parasympathetic influence on the gut.

Historical Use of Marijuana for Constipation

The use of marijuana as a laxative is not a new concept. One of the earliest examples of marijuana being used as medicine for constipation comes from China around 2700 BCE. In India, physicians have traditionally mixed hemp leaves with milk, sugar, and spices to treat constipation.

Research Findings on Marijuana and Constipation

A study published in The American Journal of Gastroenterology found that recent marijuana users had 32% lower odds of constipation compared to past or never users. The study analyzed data from 9,645 US adults between the ages of 20 and 59 who responded to drug use and bowel health questionnaires. Another study found that cannabis consumption was associated with a 30% decrease in constipation prevalence among recent users compared to non-users.

Precautions and Further Research

While marijuana can be effective in treating constipation, it is important to note that it can also cause digestive problems, especially in heavy and long-term users. Additionally, for people with constipation not related to stress or pain, cannabis could potentially worsen the issue by suppressing muscular contractions in the colon. More research is needed to fully understand the impact of marijuana on digestion and to uncover all the components of medical marijuana that affect the evacuation of fecal matter.

It can help the body relax and get into a parasympathetic state

Marijuana can help the body relax and get into a parasympathetic state, which is also known as "rest and digest". This is opposed to the sympathetic nervous system, which prepares the body to act quickly.

When the body is in a parasympathetic state, it is in a relaxed state, which is ideal for defecation. This is because, in a fight-or-flight state, the body does not want to defecate.

The endocannabinoid system (ECS) is an important regulator of gastrointestinal motility. One of the endocannabinoids, 2-AG, is a regulator of gastrointestinal motility and behaves like THC. It suppresses excessive activity in the gut and brings the system into balance.

In a 2019 study, it was found that cannabis consumption was associated with a 30% decrease in constipation.

However, it is important to note that cannabis can potentially worsen constipation if it is not related to stress or pain. This is because it can suppress muscular contractions and secretion in the colon, which is the same way it helps with diarrhea.

It can help with abdominal pain and a swollen abdomen

Marijuana has been used for medicinal purposes for thousands of years. It is known to help with a wide range of symptoms associated with many illnesses.

Individuals suffering from inflammatory bowel disease (IBD) are among those who have sought out the ameliorating properties of this plant. As legal limitations on marijuana use have eased, interest has grown from both patients and their providers regarding the potential of cannabis to be used in a clinical setting.

Abdominal pain is one of the most common symptoms of IBD. Multiple human studies have demonstrated that cannabis has a positive impact on abdominal pain. Unsurprisingly, IBD patients who use cannabis or related products frequently report taking it specifically for abdominal pain management.

The endocannabinoid system (ECS) plays a crucial role in every major aspect of gastrointestinal function and physiology, including motility, mucosal secretion, visceral pain perception, and epithelial barrier function. CB1Rs and CB2Rs are distributed throughout the central nervous system and peripheral tissues, including the gastrointestinal tract, liver, skeletal muscle, cardiovascular tissue, reproductive tissue, and adipose tissue.

CB1Rs are expressed within intestinal mucosa enteroendocrine cells and enterocytes, while CB2Rs are expressed on enterocytes as well as on neurons in the enteric nervous system. Activation of CB1R generally leads to a reduction in intestinal motility, inhibition of gastric acid secretion, and a decrease in the tone of the lower oesophageal sphincter. CB2R is also frequently expressed on immune cells, and their stimulation appears to facilitate the suppression of immune system activity and inflammation.

In summary, marijuana can help with abdominal pain and a swollen abdomen by interacting with the body's endocannabinoid system, which plays a crucial role in gastrointestinal function and visceral pain perception.

It can be used to treat opioid-induced constipation

Marijuana as a Treatment for Opioid-Induced Constipation

Marijuana has been found to have a laxative effect, with studies showing that it can reduce the risk of constipation by 30-32%. This is significant, as constipation is a common side effect of opioid medications, affecting 40-80% of patients without cancer who are receiving opioids.

Opioid-induced constipation (OIC) occurs when opioid drugs attach to receptors in the gut, lengthening the time it takes for stool to pass through the gastrointestinal system. This can cause discomfort and impact a person's quality of life.

Marijuana's laxative effect is due in part to its influence on the body's endocannabinoid system, which plays a role in regulating gastrointestinal motility. The compound 2-AG, for example, is an endocannabinoid that behaves like THC and helps regulate the sympathetic and parasympathetic influence on the gut, keeping the body in a healthy range of activity.

Additionally, marijuana can help with constipation by promoting relaxation and reducing stress and anxiety, which are factors that can inhibit defecation. The parasympathetic state induced by marijuana can facilitate the "rest and digest" process, allowing for more comfortable and efficient bowel movements.

However, it is important to note that marijuana may not be a suitable treatment for everyone. For individuals with constipation unrelated to stress or pain, marijuana could potentially worsen the issue by suppressing muscular contractions in the colon.

For those considering marijuana as a treatment for opioid-induced constipation, it is essential to consult with a healthcare professional. They can provide guidance on dosage, mode of intake, and potential interactions with other medications.

Treatment Options for Opioid-Induced Constipation

In addition to marijuana, there are several other treatment options available for OIC:

• Laxatives and stool softeners: These are typically the first line of treatment recommended by doctors. Stool softeners make it easier to pass hard, dry waste, while laxatives stimulate bowel movements.
• Increasing fluid intake: Dehydration is a common cause of constipation, and opioids can further contribute to this issue. Drinking more water and other fluids can help alleviate constipation.
• Dietary changes: Eating more fibre, particularly soluble fibre, can help regulate bowel movements. Foods such as oatmeal, barley, flax, fruits, vegetables, whole grains, seeds, and nuts are good sources of fibre.
• Physical activity: Exercise stimulates contractions in the intestinal tract and promotes bowel activity. Even gentle movements, such as walking or light stretches, can be beneficial.
• Rectal suppositories and enemas: These treatments are less commonly recommended due to their discomfort, but they can be effective in stimulating bowel activity.
• Prescription medications: In more severe cases, doctors may prescribe medications specifically designed to treat OIC. These medications block the effects of opioids in the gut and include lubiprostone (Amitiza), methylnaltrexone (Relistor), naldemedine (Symproic), and naloxegol (Movantik).

It can help with nausea and vomiting

Marijuana has been used to treat nausea for centuries. Its effectiveness in treating chemotherapy-induced nausea is widely recognised. However, its use for nausea remains under-researched in the general population.

A recent study by the University of New Mexico found that using cannabis resulted in an average symptom improvement of nearly 4 points on a 0-10 scale just moments after consumption, with increasing benefits over time. The study also found that flower and concentrates yielded faster and greater relief than edibles or tinctures, while vaping yielded less relief than consuming cannabis via a joint or pipe.

Another study, published in the American Journal of Gastroenterology, found that recent users of marijuana had 32% lower odds of constipation compared with past or never users. The study's authors suggested that this may be due to the ability of cannabinoids to activate CB1 receptor responses to other stimuli in the central nervous system, such as the insular cortex, which is involved in interoception and conscious awareness of internal bodily states.

A third study, published in the British Journal of Pharmacology, found that the primary non-psychoactive compound in cannabis, cannabidiol (CBD), also suppresses nausea and vomiting within a limited dose range. The anti-nausea/anti-emetic effects of CBD may be mediated by indirect activation of somatodendritic 5-HT1A receptors in the dorsal raphe nucleus; activation of these autoreceptors reduces the release of 5-HT in terminal forebrain regions.

In summary, marijuana can help with nausea and vomiting, especially in the context of chemotherapy treatment. The anti-nausea effects of marijuana may be due to its ability to activate CB1 receptor responses and suppress excessive sympathetic activity, helping the body to relax and shift into a "rest and digest" state. However, it is important to note that marijuana may not be effective for everyone and may even worsen constipation in some cases.
