Decisions surrounding palliative care are something that almost all of us will face at some point in our lives, whether for ourselves or for someone we care deeply about. But before that time comes, it's a subject that is often avoided or at least slightly misunderstood.
When patients face an incurable (or life-limiting) diagnosis, they are often referred to a palliative care specialist.
At its core, palliative care is about symptom control with a clear aim to improve the quality of life for patients suffering from life-limiting illnesses or those facing end-of-life care.
Can medical cannabis help? Let's find out…
Medical cannabis has been a legal treatment option for patients to consider in the UK since November 2018. It must be prescribed by a specialist doctor listed on the General Medical Council’s specialist registry.
The Cannabis sativa L. genus produces active ingredients called cannabinoids, which interact with the body's endocannabinoid system (along with other receptor pathways).
This system is crucial in regulating both physiological and cognitive processes, including pain, inflammation, mood, and appetite - all of which can be issues for patients in palliative care.
With the global rise of medical cannabis, most people have now heard of the "big two" cannabinoids - THC and CBD.
THC is responsible for most of the psychoactive effects relating to marijuana, while CBD is non-psychoactive.
That said, both have shown enormous potential for medicinal application. Below is a brief list of just some of the potential benefits of both THC and CBD.
THC may help with:
CBD may help with:
So, can medical cannabis play a role in palliative care?
Yes, but first, it's essential to understand that each patient's experience is different.
For some patients, traditional medications and treatments may be the best option for symptom control. For others, the addition of medical cannabis to their treatment plan is proving to be helpful.
The decision to pursue a medical cannabis prescription should be made only after consulting with a qualified specialist doctor. Here in the UK, only specialists listed on the General Medical Council's Specialist Register can legally prescribe cannabis-based medicines.
There is no one-size-fits-all approach when it comes to palliative care, and the same is true for medical cannabis treatment. Medical cannabis should never be seen as a 'magic cure'. Instead, it should be considered as part of a holistic treatment plan tailored to each patient's health needs.
With that said, despite medical cannabis currently being unlicensed in the UK due to insufficient studies and clinical trials, there is an ever-increasing body of clinical research that is slowly but surely uncovering the potential benefits that cannabis (and its many therapeutically active compounds) can offer patients suffering from a massive range of health concerns.
Pain is, unfortunately, often at the forefront of palliative care patients' minds.
There are many different types of pain - acute, chronic, neuropathic (nerve pain), nociceptive (normal tissue injury), referred, and psychogenic. Each has its own underlying causes, and each may have a unique response to medical cannabis treatment.
As one of the most common reasons for people to reach out to their doctor, pain, and cannabis is a topic that has been studied in greater detail.
When it comes to inflammation specifically, CBD has shown great promise in reducing inflammatory responses by interacting with various receptors in the body responsible for immune regulation, which may lead to further pain relief.
Mental health concerns often go hand-in-hand with chronic or terminal illness, and anxiety and depression are two of the most common. The burden of such a diagnosis can be overwhelming and cause immense distress, especially if the patient is facing difficult end-of-life decisions.
In terms of anxiety, the science is quite clear. Both THC and CBD have been shown to help with lowering anxiety, but in different ways and at different dosages.
This scientific review from 2017 is a good place to start. The author concluded that "Low doses of THC appear to reduce anxiety, while higher THC doses may cause increased anxiety" and that "CBD appears to decrease anxiety at all doses that have been tested".
These results are very much in line with other pieces of clinical research.
For CBD:
There is less research to pull from regarding THC for anxiety control, but there is an abundance of anecdotal evidence. Even so, it does seem quite clear that the dosage size of THC is crucial in how it affects anxiety.
Yes, medical cannabis can help with these symptoms. "The munchies" are a prominent side effect of THC, and this can be a helpful tool in stimulating the appetite of those struggling to maintain weight during palliative care.
In fact, it is a well-established treatment for nausea and appetite stimulation in cancer patients undergoing chemotherapy - one of the few 'traditional' medical applications of medical cannabis, and only one of three ways that UK patients can access cannabis-based medicines through the NHS.
Cannabis-based medications can also offer potential relief for those experiencing trouble sleeping. Life can be challenging enough as it is when dealing with a terminal illness, but add insomnia into the mix, and patients can end up feeling even more exhausted and overwhelmed.
The currently available research shows that CBD has the most potential to help with sleep issues, while THC may have mixed results depending on dosages and individual responses.
In the UK, there are two routes for patients to consider regarding legal medical cannabis access.
The first is through the NHS, but access to medical cannabis through this avenue is still very limited. Only patients with three specific health conditions (two rare forms of epilepsy, nausea and vomiting relating to chemotherapy treatment, or multiple sclerosis) can currently be prescribed medical cannabis by the NHS.
Even if you do have one of these health issues, the chances of receiving an NHS-funded prescription are exceedingly low.
The second option, which the vast majority of UK patients currently use, is to go through a private medical cannabis clinic.
Specialist doctors working with medical cannabis clinics have more flexibility than NHS doctors when it comes to prescribing, and they can consider a far wider range of conditions on a case-by-case basis.

To close out this write-up, we spoke to our expert palliative care specialist and Releaf medical cannabis consultant, Dr Edith Israel. Dr Israel has worked in palliative care across different settings, from the NHS and private care to hospices, for nearly 20 years.
Dr Israel said:
"The legalisation of medical cannabis and the emerging science backing up its application in clinical settings has increased the potential for cannabis-based therapy to play an important role for some patients receiving palliative care.
I have seen the impact that cannabis-based medicines can have on helping with pain, nausea, appetite, and even sleep. It is a very versatile medication that may offer relief to patients in their most difficult and vulnerable times, especially when conventional pharmaceuticals are ineffective.
While there are some concerns in terms of governance issues and policies, the changing landscape around medical cannabis means that we can work with patients to explore the potential benefits carefully and sensitively."

Medical cannabis treatment and finding the perfect combination of cultivar (or oil) and dosage sizing is, at least in some respect, an individualised process. Some patients find the level of symptom management they are hoping for straight away, but for others, it can take a little bit of experimentation to find the balance that works best for them.

Medical cannabis has recently hit the big time here in the UK. Although it's been legal for almost six years (since November 2018), the general public's understanding of this has been surprisingly lacking. That is, until now.
