The cannabis plant is a lot more than meets the eye.
It produces over 100 cannabinoids, or compounds. Tetrahydrocannabinolis (THC) and cannabidiol (CBD) are two of these natural compounds, and they’re what you’ll see most often when researching medical cannabis.
Although THC and CBD have many similar potential medical benefits, they can have different effects. The main difference is that THC can produce a ‘high’, while CBD doesn’t. And remember, whilst there is evidence to give a general idea of how both THC and CBD may react with the body, they can affect every individual differently.
Since 2018, medical cannabis has been legally available on prescription through licensed clinics like Alternaleaf for 50+ conditions. You can find out if you’re eligible by completing the quick eligibility checker on our website.
Below we’ll be exploring medical cannabis for constipation.
What Causes Constipation?
Constipation is when bowel movements become infrequent or difficult to pass. It can be either acute (short-term) or chronic (lasting weeks or longer). Common causes include:
- Low fibre intake
- Dehydration
- Lack of physical activity
- Changes in routine or diet
- Certain medications
- Medical conditions like IBS, IBD, hypothyroidism, or neurological disorders
The communication link between your digestive system and nervous system is known as the gut-brain axis. It also plays a key role in regulating bowel motility. When this connection is disrupted by stress, anxiety, or neurological dysfunction, it can slow digestion and lead to persistent constipation. So, what's the link between medical cannabis and digestion?
How Cannabis Interacts with the Digestive System
Medical cannabis works in the body by interacting with the endocannabinoid system, or the ECS. This is a messenger and receptor system that plays a big role in homeostasis (the management of balance) within the human body. Research suggests that the ECS influences and modulates mood, appetite, sleep, pain, and much more.
One of the core components of the ECS are the cannabinoid receptors, which includes CB1 and CB2. Many experts believe that, by consuming compounds like CBD and THC, it’s possible to interact with these receptors in the body. And that’s why medical cannabis can potentially have positive effects for so many different conditions.
THC primarily activates CB1 receptors, which can potentially slow gastrointestinal motility, and sometimes ease cramping or diarrhea.
On the other hand, effects are more complex when it comes to CBD and constipation. CBD indirectly influences both CB1 and CB2 receptors to help reduce gut inflammation, ease discomfort, and regulate motility.
Together, cannabinoids may support digestive balance, especially in conditions like IBS or IBD, though can vary from person to person. And this idea that both CBD and THC can play a lead role on certain health conditions, and can sometimes be greater together, is a phenomenon known as the entourage effect.
Can Medical Cannabis Help with Constipation Symptoms?
So, we’ve explored above that, yes, medical cannabis may help with bloating, cramping, and IBS-related symptoms in some people. But, there is no one size fits all when it comes to medical cannabis and constipation. Just like with other traditional medications, the way your body reacts may be different to someone else's experience, and effects can vary between individuals.
Let’s rewind and go back to THC and bowel movement. As we mentioned above, THC can potentially slow bowel movements by activating CB1 receptors in the gut. And although this may help with diarrhea, it could worsen constipation, especially with long-term or high-dose use.
So, we recommend always following the guidance of your clinician. Speak to them if you experience any issues or unwanted side effects - they’re there to help, not judge.
Is Medical Cannabis Prescribed for Digestive Conditions in the UK?
Yes, medical cannabis can be prescribed for conditions such as IBS, Crohn’s disease, or chronic GI discomfort. It’s actually been legal in the UK since 1st November 2018 when prescribed by a specialist doctor, like the ones found at licensed medical cannabis clinics like Alternaleaf.
To be eligible, you’ll need a diagnosis for a qualifying condition, and to have been offered at least two conventional treatments for this condition. This can include medication, talking therapy, physiotherapy, surgery and anything else prescribed by your GP. Keep in mind, if you’re pregnant or have a history of psychosis or schizophrenia, you won’t qualify.
Just because it’s legal in the UK, doesn’t mean it’s legal everywhere. It’s always a good idea to check if you’re travelling somewhere, what their rules and laws are around medical cannabis.
We prescribe for 50+ other conditions at Alternaleaf, including chronic pain, anxiety, depression, ADHD and autism. We offer expert guidance throughout your medical cannabis journey to ensure safe and effective use.

Summary
Constipation can be complex, with causes ranging from simple lifestyle factors to deeper issues within the gut-brain connection. While traditional treatments exist, emerging research suggests that medical cannabis may offer relief by potentially supporting gut function, reducing inflammation, and easing discomfort. Particularly CBD for bloating and other symptoms.
The best thing to do is speak to your clinician, or seek the help of a licensed medical cannabis clinic like Alternaleaf if you’re considering medical cannabis for gut health.
