Synopsis of Cannabis Research for Inflammatory Bowel Disease

The diverse groups of trials, including a growing number of clinical studies, that directly examined the treatment potential of cannabinoid-based therapeutics (CBT) to address signs and symptoms of colitis, such as gut inflammation, motility, and visceral pains for example, present several insights:



  • Various components of the endocannabinoid system (ECS), such as anandamide (AEA) 2-arachidonoylglycerol (2-AG) and their respective degrading enzyme FAAH (via the use of inhibitors) and MAGL acting on CB1, CB2, PPARs, TRPs play a significant role in protecting, restoring and maintaining gut health and well-being in both acute and chronic forms of colitis.


In the most recent meta-analyses (2022), the authors believe that CBT may play a therapeutic role in managing patients with inflammatory bowel diseases (IBD), especially in managing pain. Furthermore, they suggest that cannabinoid-based therapeutics (such as adjuvant therapy) may increase the chances of success for standard Crohn’s disease treatment.


At the same time, its usage in cases of ulcerative colitis was not recommended.


The authors highlight that low-dose treatment may be more effective than higher doses. 


Given the currently available scientific data, oral CBD is the most optimal administration route.


CB1 and CB2 receptor agonism is largely considered anti-inflammatory, while CB1 and CB2 receptor antagonism is posited to be pro-inflammatory.


CBD was the most investigated cannabinoid, followed by other cannabis constituents such as THC, THCA, and CBG.


Cannabis common terpenes shown to proceed therapeutic effects for this patient population include beta-Caryophyllene (a CB2 agonist), limonene, humulene, borneol, and geraniol.


Synthetic cannabinoids such as HU-210 display protective effects in animal models of colitis. To provide the reader with some context, HU210 is a full agonist at CB1 and CB2 (meaning that HU-210 is about 100 x more potent than THC at CB1 and about 86 x more potent than THC at CB2).


Synergies were reported for the co-administration of cannabis and turmeric in IBD and IBS.

Overview - Inflammatory Bowel Disease

Description of Inflammatory Bowel Disease

Colitis is derived from the Greek words for large intestines, kolon, and -itis, the latter pertaining to diseases characterized by inflammation. As such, colitis describes inflammation of the colon.


The most common expressions are ulcerative colitis (affects the colon only) and Crohn's disease (affects the entire GI tract), both of which constitute actual inflammatory bowel disease (IBD). 


Inflammatory bowel disease (IBD) differs from irritable bowel syndrome (IBS). IBD causes physically overt and measurable destruction, harm to intestines, inflammation, and may increase the risk for colon cancer, whereas IBS does not.  


Several additional types of colitis are categorized according to underlying causes, such as autoimmune colitis, ischemic colitis, allergic colitis, drug- or chemotherapy-induced colitis, and microscopic or infectious colitis (e.g., salmonella, tuberculosis). 


To date, there is no cure within the model of modern medicine for the chronic type, and treatment is limited to supportive therapies such as hydration via IV fluids, pharmaceutical intervention (e.g., antibiotics, 5-ASA, or steroids to depress the immune system), iron supplements to balance anemia or surgery.


In severe cases, hospitalization may be necessary.


Some progress has been reported with specific dietary regimes and microbiome-supportive supplements.

Drug Interactions

THC Interaction with Pharmaceutical Drugs

  • Tetrahydrocannabinol (THC) can enhance the effects of drugs that cause sedation and depress the central nervous system, such as benzodiazepines, barbiturates, and alcohol. 
  • THC is metabolized by an inhibitor of several enzymatic liver pathways referred to as cytochrome P450 (aka CYP450). There are more than 50 enzymes belonging to this enzyme family, several of which are responsible for the breakdown of common drugs such as antidepressants (e.g., amitriptyline, doxepin, fluvoxamine), antipsychotics (haloperidol, clozapine, Stelazine), beta-blockers (e.g., propranolol), bronchodilators (e.g., theophylline), or blood thinners (e.g., warfarin). Thus, patients taking these medication classes may find that THC increases the concentration and effects of these drugs and the impact duration.
  • Clinical observation (not yet confirmed by clinical trials) suggests no likely interactions with other pharmaceuticals at a total daily dose of up to 20mg THC.

CBD Interaction with Pharmaceutical Drugs

  • Cannabidiol (CBD) may alter the action of metabolic enzymes (specific drug-transport mechanisms) and alter interactions with other drugs, some of which may produce therapeutic or adverse effects. For instance, CBD interacts with the enzyme cytochrome P450 3A4 and cytochrome P450 2C19, increasing the bioavailability of anti-epileptic drugs such as clobazam (a benzodiazepine). This makes it possible to achieve the same results at significantly lower dosages, reducing treatment costs and risks of adverse effects. 
  • Groups of drugs affected include anti-epileptics, psychiatric drugs, and drugs affecting metabolic enzymes.
  • Clinical observations (not yet confirmed by clinical trials) suggest no likely interactions with other pharmaceuticals at a total daily dose of up to 100mg CBD.

THC/CBD Interaction with Pharmaceutical Drugs

In general, when using cannabinoid-based therapeutics that contain both THC and CBD consider the ratio between them and weigh the relevant information displayed in the individual THC and CBD Drug Interaction windows accordingly.

Concerns about Cannabis and Cancer-related Immunotherapies:
Some recent clinical observational studies have suggested that the co-administration of cannabinoid-based therapeutics and immunotherapy or immune checkpoint inhibitors in the treatment of certain types of cancer has been associated with worse overall survival rates (T. Taha et al., 2019; A. Biedny et al., 2020; G. Bar-Sela et al., 2020).

However, other studies have suggested that the co-commitment use of immune checkpoint inhibitors and cannabis-induced no such deleterious effects. More specifically, one trial was conducted on animals resulting in data suggesting that cannabis did not negatively affect the properties of immune checkpoint inhibitors (B. Waissengrin et al., 2023). The same authors compared the previous study results with findings from a cohort of 201 patients with metastatic non-small cell lung cancer who received treatment with monotherapy pembrolizumab as a first-line treatment and adjunct cannabis to treat mainly pain and loss of appetite. Their time to tumor progression was 6.1 versus 5.6 months, and overall survival differed between 54.9 versus 23.6 months in cannabis-naïve patients and cannabis-using patients, respectively. However, while numerically different, the authors write that these differences were not statistically significant, leading them to suggest that “These data provide reassurance regarding the absence of a deleterious effect of cannabis in this clinical setting.”

Dosing Considerations

THC Dosage Considerations

  • THC micro dose:  0.1 mg to 0.4 mg
  • THC low dose:  0.5 mg to 5 mg
  • THC medium dose:  6 mg to 20 mg
  • THC high dose:  21 mg to 50+ mg

CBD Dosage Considerations

  • CBD low dose:  0.4 mg to 19 mg
  • CBD medium dose: 20 mg to 99 mg
  • CBD high dose:  100 mg to 800+ mg (upper limits tested ~1,500mg)
