CBD Oil for Stomach Ulcers: Using Cannabidiol To Treat Gastric Pain

People use CBD to treat a whole range of medical conditions, including stomach problems like ulcers.

The presence of cannabinoid receptors in the digestive system makes it clear that cannabis compounds like CBD can affect its performance. For example, we know that CBD can relieve nausea and pain on top of reducing inflammation.

All of the above properties can prove useful for stomach ulcers.

But what does science say about taking CBD oil for ulcers and other digestive issues?

Here’s everything you need to know.

How to Tell If You Have Stomach Ulcers

Stomach ulcers — also known as peptic or gastric ulcers — occur when the lining of the stomach gets severely damaged. They can also affect the esophagus as well as the duodenum, which is the upper part of the small intestine.

Stomach ulcers can appear at any age and are a common problem for the U.S. population. However, men are more likely to have it than women, especially if they’re close to their 60s.

Potential Causes of Stomach Ulcers

People develop stomach ulcers for a few different reasons.

One of the most common triggers is a bacteria known as helicobacter pylori or h.pylori in short.

When these bacteria spread across the stomach, they cause inflammation, which can eventually turn into ulcers. H.pylori contributes to 70–90% of stomach ulcers.

People who regularly take non-steroidal anti-inflammatory drugs (NSAIDs) are also at higher risk of developing gastric ulcers. Common NSAIDs include aspirin, diclofenac, ibuprofen, and naproxen.

People often take these medications to deal with problems like muscle and joint pain. However, when used frequently, they can result in the irritation of the stomach lining — leading to ulcers. It’s possible to decrease the risk by taking NSAIDs after a meal.

Despite limited evidence, some people believe that lifestyle factors such as stress and diet can also spur up the development of stomach ulcers. Things like spicy food, cigarettes, and alcohol can further irritate the stomach and deteriorate the condition.

Stomach Ulcers Symptoms

Abdominal pain is the most common symptom of stomach ulcers. Patients describe that feeling as a burning or gnawing sensation that typically occurs 2–3 hours after having a meal or at night. It usually begins in the central abdomen but can spread to the chest, back, or belly button.

Other symptoms of stomach ulcers include:

  • Nausea
  • Heartburn/GERD
  • Loss of appetite
  • Indigestion
  • Weight loss

Untreated severe ulcers can cause internal bleeding. If any of the following symptoms occur, you should immediately seek medical attention:

  • Sudden, severe pain that gets worse with time
  • Bloody vomit
  • Dark, sticky stools

How Are Stomach Ulcers Typically Treated?

Doctors usually recommend proton pump inhibitors (PPI) such as omeprazole and lansoprazole for treating stomach ulcers.

PPIs slow down acid production in the stomach, consequently reducing irritation. However, if someone has an h.pylori infection, they will need to add antibiotics to their PPI treatment.

Although the above medications may offer temporary relief from stomach ulcer symptoms, they will keep returning until the underlying problem is resolved. Moreover, since PPIs reduce acid production in the stomach, they can cause problems with digestion.

Does CBD Help Treat Stomach Ulcers?

CBD and other cannabis compounds have recently received much attention from medical researchers, especially when it comes to treating digestive issues. Many studies suggest CBD could help with conditions such as Crohn’s disease or colitis, both of which are inflammatory bowel diseases.

We also have some evidence that cannabinoids could help protect the stomach lining from damage, thus reducing the risk of developing ulcers.

The “why” behind the above effects lies in the relationship between plant-based cannabinoids and the human endocannabinoid system (ECS). (1)

The ECS is the major regulatory network in our bodies, with cannabinoid receptors (CB1 and CB2) appearing in every human organ system including the central nervous and the digestive systems.

The ECS also enables the active compounds in cannabis to exert their actions. For example, there is evidence that the signaling of CB1 receptors using cannabinoids blocks gastric acid secretion in humans and the experimental models of animals.

Studies have demonstrated that CBD can reduce the amount of gastric acid and increase blood flow to the stomach’s lining.

In a 2016 study published in Current Neuropharmacology, the authors found that the activation of CB1 receptors by cannabinoids can reduce both gastric motor activity and gastric acid secretion on top of decreasing the formation of lesions on the stomach lining (2).

In another study, the research team investigated the ability of cannabinoids to act on the gastrointestinal tract of some species, including mice, rats, guinea pigs, and humans (3).

Finally, a study from the Pharmacology Journal has found that THC inhibited ulcer formation in animal models, which are promising findings for those living in places where medical marijuana is legal. Such people can use both CBD and THC to amplify the effects of one another (4).

Although the above studies discussed cannabinoids in general — only mentioning CBD — the results are still promising. The authors believe that the endocannabinoid system may be deeply involved in the treatment of ulceration, inflammation, and gastric mucosal lesions.

CBD Oil for Stomach Ulcer Symptoms

In addition to potentially preventing and treating stomach ulcers, CBD could help with some of the stomach ulcer symptoms too.

Here’s what you need to know.

Pain

Many people turn to CBD oil for natural pain relief. Humans have been using cannabis for this reason for millennia; furthermore, a massive amount of research into CBD for pain provides clear results that this cannabinoid can address pain on several levels (5).

On top of helping with digestive pain, CBD oil could provide a safer option to NSAIDs for people who use them for migraines prevention or arthritis.

Nausea

Nausea often accompanies pain as the second most common stomach ulcer symptom. Research into CBD and nausea suggests CBD can act on the areas of the brain that control nausea and vomiting. However, CBD doesn’t do it directly. Instead, it signals the endocannabinoid system to regulate these functions (6).

Can CBD Worsen Stomach Ulcers?

There is anecdotal evidence coming from some CBD users that CBD oil can make you feel sick. However, gastrointestinal distress and upset stomach aren’t typically caused by CBD but rather by ingredients used to transport CBD oil into the body, or when something goes wrong during production.

Dr. Kenneth Brown, MD, a board-certified gastroenterologist and doctor of internal medicine in Plano, TX, says that it would be against CBD’s nature to “attack” the digestive system.

“It’s been shown [CBD] to help decrease acid reflux and heal ulcers,” he says. “In my practice, when someone has gastrointestinal issues with CBD, we start with the product, because many times that may be a reason they are feeling sick. Just like all other health supplements, the quality and the source of CBD oil make all the difference.”

Cannabis plants are bioaccumulators, meaning they draw both the good and bad substances from the soil. If hemp is grown in poor soil or undergoes aggressive extraction involving hydrocarbons, it will not only diminish the quality of the end product but it can also make it dangerous for your health.

Another potential reason why people may feel sick after taking CBD oil is the carrier it has been suspended in.

According to Michele Ross, Ph.D., CEO of Infused Health and a leading cannabinoid medicine researcher, “if you are experiencing gastrointestinal distress symptoms or an upset stomach, you may have a sensitivity, especially to coconut/MCT oil, which is the most common carrier I’ve seen. Many people can experience abdominal cramping and stomach pain, especially when consuming large quantities,” she said.

Does CBD Oil Have Side Effects?

Now that we’ve established stomach issues experienced by some CBD users are typically caused by the poor quality ingredients or production flaws, let’s discuss other potential side effects of CBD.

Several health organizations, including the World Health Organization (WHO), have acknowledged CBD as having a remarkable safety profile. This 2017 study showed that CBD was well-tolerated by humans in daily doses of up to 1,500 mg.

That being said, there are a few mild side effects you should be aware of.

For example, CBD can cause a dry mouth feeling due to its interaction with the salivary glands in the mouth. In simple terms, CBD and other cannabinoids can inhibit saliva production, resulting in increased thirst.

Another potential side effect — when you take high doses of CBD — is a temporary drop in the blood pressure that can make you feel dizzy and sleepy. While this may be the desired effect among those who take CBD oil for insomnia, some people may feel tired after taking high doses in the morning. If you don’t want to feel sleepy after taking CBD oil, use lower doses to boost focus and productivity while still receiving a gentle calming effect.

There’s also the risk of potential CBD-drug interactions. CBD is known to interact with many medications because it inhibits the system of enzymes that breaks them down in the liver — resulting in subtherapeutic effects or, on the contrary, in toxicity. Always make sure to consult your doctor before buying CBD oil if you take any prescription medication for stomach ulcers.

CBD Dosage for Stomach Ulcers

Every person has unique body chemistry, different metabolism rate, weight, and severity of symptoms, so what works for you may not necessarily work for your neighbor, even though you share the same condition.

Given this, finding the right dose of CBD for your stomach ulcer problems is an experimental process. The best way to go about finding the amount that works for you is to take 1–6 mg of CBD for every 10 pounds of your body weight. Continue to take this dose for 3–7 days, monitoring how CBD affects your painful symptoms.

While you may not see the direct effects on your stomach lining, you can certainly experience relief from nausea, pain, or inflammation.

If the initial dosage fails to ease your symptoms, you can increase the dosage by 5 mg until you find a dose that works.

Final Thoughts: Should You Take CBD Oil for Stomach Ulcers?

While no study has yet investigated the efficacy of CBD as the only treatment for stomach ulcers, several animal and human studies have pointed to cannabinoids as potential relievers of many digestive problems.

CBD is a potent anti-inflammatory; it can also affect pain by blocking its signals, not to mention the relief from nausea and improved appetite. Even though the scientific evidence is fresh, you can use CBD oil as an adjunctive treatment for your stomach ulcers.

Make sure to stay vigilant against poor-quality products that are churned out by some companies to capitalize on the booming market. Quality issues with CBD oils can result in an upset stomach and even worsen your ulcers. Always seek out reputable companies that use organically grown hemp and test their products in third-party laboratories for potency and purity.

Cannabinoids Treat Gastrointestinal Disorders

Peptic Ulcer

A peptic ulcer is erosion in the lining of the stomach or the first part of the small intestine, an area called the duodenum.
If the peptic ulcer is located in the stomach, it is called a gastric ulcer.
A peptic ulcer, also known as PUD or peptic ulcer disease, is the most common ulcer of an area of the gastrointestinal tract that is usually acidic and thus extremely painful. It is defined as mucosal erosions equal to or greater than 0.5 cm. As many as seventy to ninety percent of such ulcers are associated with Helicobacter pylori, a spiral-shaped bacterium that lives in the acidic environment of the stomach; however, only forty percent of those cases go to a doctor. Ulcers can also be caused or worsened by drugs such as aspirin, Plavix (clopidogrel), ibuprofen, and other NSAIDs.

Contrary to general belief, four times as many peptic ulcers arise in the duodenum—the first part of the small intestine, just after the stomach—rather than in the stomach itself. About four percent of stomach ulcers are caused by a malignant tumor, so multiple biopsies are needed to exclude cancer. Duodenal ulcers are generally benign.

Causes

A major causative factor (60% of gastric and up to 90% of duodenal ulcers) is chronic inflammation due to Helicobacter pylori that colonizes the antral mucosa. The immune system is unable to clear the infection, despite the appearance of antibodies. Thus, the bacterium can cause a chronic active gastritis (type B gastritis), resulting in a defect in the regulation of gastrin production by that part of the stomach, and gastrin secretion can either be increased, or as in most cases, decreased, resulting in hypo- or achlorhydria. Gastrin stimulates the production of gastric acid by parietal cells and, in H. pylori colonization responses that increase gastrin, the increase in acid can contribute to the erosion of the mucosa and therefore ulcer formation.

Another major cause is the use of NSAIDs . The gastric mucosa protects itself from gastric acid with a layer of mucus, the secretion of which is stimulated by certain prostaglandins. NSAIDs block the function of cyclooxygenase 1 (cox-1), which is essential for the production of these prostaglandins. COX-2 selective anti-inflammatories (such as celecoxib or the since withdrawn rofecoxib) preferentially inhibit cox-2, which is less essential in the gastric mucosa, and roughly halve the risk of NSAID-related gastric ulceration. As the prevalence of H. pylori-caused ulceration declines in the Western world due to increased medical treatment, a greater proportion of ulcers will be due to increasing NSAID use among individuals with pain syndromes as well as the growth of aging populations that develop arthritis.

The incidence of duodenal ulcers has dropped significantly during the last 30 years, while the incidence of gastric ulcers has shown a small increase, mainly caused by the widespread use of NSAIDs. The drop in incidence is considered to be a cohort-phenomenon independent of the progress in treatment of the disease. The cohort-phenomenon is probably explained by improved standards of living which has lowered the incidence of H. pylori infections.

Although some studies have found correlations between smoking and ulcer formation, others have been more specific in exploring the risks involved and have found that smoking by itself may not be much of a risk factor unless associated with H. pylori infection. Some suggested risk factors such as diet, spice consumption and blood type, were hypothesized as ulcerogens (helping cause ulcers) until late in the 20th century, but have been shown to be of relatively minor importance in the development of peptic ulcers. Similarly, while studies have found that alcohol consumption increases risk when associated with H. pylori infection, it does not seem to independently increase risk, and even when coupled with H. pylori infection, the increase is modest in comparison to the primary risk factor.

Gastrinomas (Zollinger Ellison syndrome), rare gastrin-secreting tumors, also cause multiple and difficult-to-heal ulcers.
Most ulcers occur in the first layer of the inner lining. A hole that goes all the way through the stomach or duodenum is called a perforation. A perforation is a medical emergency.The following also raise your risk for peptic ulcers:

  • Drinking too much alcohol
  • Regular use of aspirin, ibuprofen, naproxen, or other nonsteroidal anti-inflammatory drugs (NSAIDs). Taking aspirin or NSAIDs once in awhile is safe for most people.
  • Smoking cigarettes or chewing tobacco
  • Being very ill, such as being on a breathing machine
  • Radiation treatments

Many people believe that stress causes ulcers. It is not clear if this is true, at least for everyday stress at home.
The diagnosis is mainly established based on the characteristic symptoms. Stomach pain is usually the first signal of a peptic ulcer. In some cases, doctors may treat ulcers without diagnosing them with specific tests and observe whether the symptoms resolve, this indicating that their primary diagnosis was accurate.

Symptoms

Small ulcers may not cause any symptoms. Some ulcers can cause serious bleeding.

  • Abdominal pain is a common symptom but it doesn’t always occur. The pain can differ a lot from person to person.
  • Feeling of fullness unable to drink as much fluid
  • Hunger and an empty feeling in the stomach, often 1 – 3 hours after a meal
  • Mild nausea (vomiting may relieve symptom)
  • Pain or discomfort in the upper abdomen
  • Upper abdominal pain that wakes you up at night
  • Other possible symptoms include:
  • Bloody or dark tarry stools
  • Chest pain
  • Fatigue
  • Vomiting, possibly bloody
  • Weight loss

Treatment

The best way to stop any further growth of a stomach ulcer is to follow a healthy diet. It must contain non-acidic meals along with liquid meals. Sour agents like lemon should be strictly avoided in the diet. Younger patients with ulcer-like symptoms are often treated with antacids or H2 antagonists before EGD is undertaken. Bismuth compounds may actually reduce or even clear organisms, though the warning labels of some bismuth subsalicylate products indicate that the product should not be used by someone with an ulcer.

Patients who are taking nonsteroidal anti-inflammatories (NSAIDs) may also be prescribed a prostaglandin analogue (Misoprostol) in order to help prevent peptic ulcers, which may be a side-effect of the NSAIDs.
When H. pylori infection is present, the most effective treatments are combinations of two antibiotics (e.g. Clarithromycin, Amoxicillin, Tetracycline, Metronidazole) and one proton pump inhibitor (PPI), sometimes together with a bismuth compound. In complicated, treatment-resistant cases, three antibiotics (e.g. amoxicillin + clarithromycin + metronidazole) may be used together with a PPI and sometimes with bismuth compound. An effective first-line therapy for uncomplicated cases would be Amoxicillin + Metronidazole + Pantoprazole (a PPI). In the absence of H. pylori, long-term higher dose PPIs are often used.

Treatment of H. pylori usually leads to clearing of infection, relief of symptoms and eventual healing of ulcers. Recurrence of infection can occur and retreatment may be required, if necessary with other antibiotics. Since the widespread use of PPI’s in the 1990s, surgical procedures (like “highly selective vagotomy”) for uncomplicated peptic ulcers became obsolete.
Perforated peptic ulcer is a surgical emergency and requires surgical repair of the perforation. Most bleeding ulcers require endoscopy urgently to stop bleeding with cautery, injection, or clipping.

Ranitidine provides relief of peptic ulcers, heartburn, indigestion and excess stomach acid and prevention of these symptoms associated with excessive consumption of food and drink. Ranitidine is available over the counter from a pharmacy and works by decreasing the amount of acid the stomach produces allowing healing of ulcers. Zantac tablets contain Ranitidine ( 150 mg) as the active ingredient which can also be bought generically.

Sucralfate, (Carafate) has also been a successful treatment of peptic ulcers.

Complications

Gastrointestinal bleeding is the most common complication. Sudden large bleeding can be life-threatening. It occurs when the ulcer erodes one of the blood vessels, such as the gastroduodenal artery.
Perforation (a hole in the wall) often leads to catastrophic consequences. Erosion of the gastro-intestinal wall by the ulcer leads to spillage of stomach or intestinal content into the abdominal cavity. Perforation at the anterior surface of the stomach leads to acute peritonitis, initially chemical and later bacterial peritonitis. The first sign is often sudden intense abdominal pain.

  • Bleeding inside the body (internal bleeding)
  • Gastric outlet obstruction
  • Inflammation of the tissue that lines the wall of the abdomen (peritonitis)
  • Perforation of the stomach and intestines

Posterior wall perforation leads to bleeding due to involvement of gastroduodenal artery that lies posterior to the first part of duodenum.
Penetration is when the ulcer continues into adjacent organs such as the liver and pancreas.
Scarring and swelling due to ulcers causes narrowing in the duodenum and gastric outlet obstruction. Patient often presents with severe vomiting.
Cancer is included in the differential diagnosis (elucidated by biopsy), Helicobacter pylori as the etiological factor making it three to six times more likely to develop stomach cancer from the ulcer.
Peptic ulcers tend to come back if untreated. If you follow your doctor’s treatment instructions and take all of your medications as directed, the H. pylori infection will be cured and you will be much less likely to get another ulcer.

Prevention

Avoid aspirin, ibuprofen, naproxen, and other NSAIDs. Try acetaminophen instead. If you must take such medicines, talk to your doctor first. Your doctor may:

  • Test you for H. pylori first
  • Have you take proton pump inhibitors (PPIs) or an acid blocker
  • Have you take a drug called misoprostol
  • The following lifestyle changes may help prevent peptic ulcers:
  • Do not smoke or chew tobacco.
  • Limit alcohol to no more than two drinks per day.

History

John Lykoudis, a general practitioner in Greece, treated patients for peptic ulcer disease with antibiotics, beginning in 1958, long before it was commonly recognized that bacteria were a dominant cause for the disease.
Helicobacter pylori was rediscovered in 1982 by two Australian scientists, Robin Warren and Barry J. Marshall as a causative factor for ulcers. In their original paper, Warren and Marshall contended that most stomach ulcers and gastritis were caused by colonization with this bacterium, not by stress or spicy food as had been assumed before.

The H. pylori hypothesis was poorly received, so in an act of self-experimentation Marshall drank a Petri dish containing a culture of organisms extracted from a patient and five days later developed gastritis. His symptoms disappeared after two weeks, but he took antibiotics to kill the remaining bacteria at the urging of his wife, since halitosis is one of the symptoms of infection. This experiment was published in 1984 in the Australian Medical Journal and is among the most cited articles from the journal.

In 1997, the Centers for Disease Control and Prevention, with other government agencies, academic institutions, and industry, launched a national education campaign to inform health care providers and consumers about the link between H. pylori and ulcers. This campaign reinforced the news that ulcers are a curable infection, and that health can be greatly improved and money saved by disseminating information about H. pylori.
In 2005, the Karolinska Institute in Stockholm awarded the Nobel Prize in Physiology or Medicine to Dr. Marshall and his long-time collaborator Dr. Warren “for their discovery of the bacterium Helicobacter pylori and its role in gastritis and peptic ulcer disease.” Professor Marshall continues research related to H. pylori and runs a molecular biology lab at UWA in Perth, Western Australia.

It was a previously widely accepted misunderstanding that the use of chewing gum resulted in gastric ulcers. The medical profession believed that mastication stimulated production of hydrochloric acid in the stomach and that hyperchlorhydria in the absence of food would erode the stomach lining.

On the other hand, in the recent past, some believed that mastic gum, a tree resin extract, actively eliminates the H. pylori bacteria. However, multiple subsequent studies have found no effect of using mastic gum on reducing H. pylori levels.

Medical Marijuana and Peptic Ulcers

Medical benefits of marijuana for people with gastrointestinal disorders were backed up by the United States Institute of Medicine medical marijuana study. According to the Institute, “For patients who suffer simultaneously from severe pain, nausea, and appetite loss, cannabinoid drugs might offer broad-spectrum relief not found in any other single medication.”
Medical marijuana can be used to treat a variety of diseases and symptoms related to the gastrointestinal system. Cannabis helps combat cramping that accompanies many GI disorders because cannabinoids relax contractions of the smooth muscle of the intestines. Research shows that the body’s own cannabinoids, known as anandamides, affect neurological systems that control the gastrointestinal system. External and internal cannabinoids strongly control gastrointestinal motility and inflammation. They also have the ability to decrease gastrointestinal fluid secretion and inflammation. This means that cannabis can be useful to stop ulcers and other syndromes.
Studies indicate that cannabinoids in marijuana bind with cannabinoid receptors in the digestive tract, especially the small and large intestine, causing muscle relaxation, reduction of inflammation, analgesia, increased nerve-muscle coordination, anti-emesis, and relief of spasms such as those that cause nausea.

The overall opinion of enlightened people in the medical community is that medical cannabis can interact with the endogenous cannabinoid system to reduce problems associated with nausea, vomiting, gastric ulcers, irritable bowel syndrome, Crohn’s disease, secretory diarrhea, paralytic ileus and gastroesophageal reflux disease.
There are no clinical studies with cannabinoids in gastric ulcers. However, THC and other substances that bind to the cannabinoid-1-receptor (CB1 receptor agonists) inhibited the gastric acid production in humans and the formation of ulcers in animals.
The nervous system of the bowel of several species, including the mouse, rat, guinea pig and humans, contains cannabinoid CB1 receptors that depress motility of stomach and intestine.
Gastric acid secretion is also inhibited in response to CB1 receptor activation, although the detailed underlying mechanism has yet to be elucidated. Cannabinoid receptor agonists delay gastric emptying in humans as well as in rodents and probably also inhibit human gastric acid secretion.

The extent to which the effects on gastrointestinal function of cannabinoid receptor agonists or antagonists/inverse agonists can be exploited therapeutically has yet to be investigated as has the extent to which these drugs can provoke unwanted effects in the gastrointestinal tract when used for other therapeutic purposes.

Increasing number of evidence suggest that gastric mucosal protection can be induced also centrally. Several neuropeptides, such as TRH, amylin, adrenomedullin, enkephalin, β-endorphin, nociceptin, nocistatin, ghrelin or orexin given centrally induce gastroprotection and the dorsal vagal complex and vagal nerve may play prominent role in this centrally initiated effect. Since also cannabinoid receptors are present in the dorsal vagal complex, we aimed to study whether activation of central cannabinoid receptors result in gastric mucosal defense and whether there is an interaction between cannabinoids and endogenous opioids. Gastric mucosal damage was induced by 100% ethanol in rats. The cannabinoids were given intravenously (i.v.) or intracerebroventricularly (i.c.v.), while the antagonists were given i.c.v or intracisternally (i.c.). Gastric lesions were evaluated macroscopically 60 min later. Anandamide, methanandamide and WIN55,212-2 reduced ethanol-induced mucosal lesions after both peripheral (0.28-5.6 µmol/kg, 0.7-5.6 µmol/kg and 0.05-0.2 µmol/kg i.v., respectively) and central (2.9-115 nmol/rat, 0.27-70 nmol/rat and 1.9-38 nmol/rat i.c.v., respectively) administration. The gastroprotective effect of anandamide and methanandamide given i.c.v. or i.v.was reversed by the CB1 receptor antagonist SR141716A (2.16 nmol i.c.v.). Naloxone (27.5 nmol i.c.v.) also antagonized the effect of i.c.v. or i.v. injected anandamide
and WIN55,212-2, but less affected that of methanandamide. The gastroprotective effect of anandamide was diminished also by endomorphin-2 antiserum. In conclusion it was first demonstrated that activation of central CB1 receptors results in gastroprotective effect. The effect is mediated at least partly by endogenous opioids.

The current state of knowledge of the biochemistry of cannabinoids is increasing at an exponential rate and, with discoveries of cannabinoid receptors in unexpected areas of the body, new potential research/treatment avenues are appearing at an increasing rate.

Grinspoon[i] reports anecdotal use of cannabis to control bowel movements in multiple sclerosis, and relief from the symptoms of Crohn”s disease. Mikuriya[ii] records irritable bowel syndrome, as well as other inflammatory gastrointestinal conditions (principally among AIDS patients), as one of a wide variety of conditions for which cannabis has been prescribed or recommended for therapeutic use in California. Consroe et al[iii], in an anonymous survey of 112 MS patients, found a large proportion reported improvements in bowel and bladder dysfunction from smoked cannabis. There are no clinical trials currently published, although I understand GW trials of cannabis extracts on patients with bowel disorders are either under way or at an advanced stage of planning.

However, there does appear to be some scientific support for claimed therapeutic benefits, from the research literature concerning the actions and metabolism of cannabinoids and cannabinoid receptors. The wall of the intestine is composed of a type of muscle known as “smooth muscle”, also found lining the walls of arteries and in other involuntary functions. Cannabinoids relax smooth muscles.
Intestinal Motility and Irritable Bowel Syndrome:
The CB1 cannabinoid receptor has specifically been found to inhibit motility of the intestine in a variety of laboratory and farm animals. The effect is specific, indicating that endogenous cannabinoids to be responsible for regulating smooth muscle tone in the intesting, and the rate of peristalsis.

Summary – Cannabinoids and the GI Tract:

While I am not aware of any published results from controlled human studies of medical use of cannabis in the treatment of conditions such as gastric ulcers or irritable bowel syndrome, there appears to be sufficient animal evidence of the potential efficacy of cannabis in reducing intestinal spasms, ulceration and gastric acid secretion to merit further research into this and related indications.

Any symptomatic relief obtained from smoking cannabis, or use via inhalers or sublingual sprays, would occur far more rapidly than with oral preparations.
Given this verified list of problems that can be created by prescription drugs used to treat gastrointestinal disorders, and the lack of such problems caused by medical marijuana which provides better relief, it’s amazing that medical marijuana is not already the most popularly prescribed medication for such disorders.”
Licensed medical marijuana grower-patients who grow medical marijuana using organic ingredients and properly engineered synthetic ingredients have told us that cannabis provides a wide range of relief, without severe side-effects, in ways that other drugs, treatment and surgery do not.
