Core symptoms of CRPS include intense pain (often described as a burning, throbbing, or stabbing pain), heightened skin sensitivity, swelling and stiffness around the joints, and discolouration of the skin. There are two types of CRPS (commonly referred to as ‘type 1’ and ‘type 2’), but both are much the same in terms of symptoms and treatment options. Medical cannabis can be prescribed for both types of CRPS.
While many patients find relief from medications such as gabapentinoids, antidepressants and opioids, others do not, or would rather try a plant-based option. Medical cannabis offers a promising alternative, with many studies suggesting cannabinoids can help to ease many of the issues associated with CRPS. Some patients also choose to take medical cannabis alongside their current medication; however, this should only ever be done under close clinical guidance to avoid negative interactions or side effects.
Here’s everything you need to know about medical cannabis for CRPS.
Are medical cannabis treatments suitable for complex regional pain syndrome patients?
Medical cannabis treatments, in the form of dried cannabis flower to vaporise, THC vapes, cannabis oil and cannabis pastilles, are available on prescription for CRPS via private clinics. It is not possible to access cannabis or cannabis-based medicines for complex regional pain syndrome on the NHS.
Which CRPS symptoms might medical cannabis help with? (pain, sleep, muscle spasms, mobility)
A recent study titled ‘UK Medical Cannabis Registry: A Clinical Outcomes Analysis for Complex Regional Pain Syndrome' suggests that cannabis could provide an effective treatment for CRPS. The results concluded that cannabis-based medicinal products offered pain relief and improved quality of life to CRPS patients.
Research regarding medical cannabis for sleep issues and muscle spasms is fairly comprehensive, as these symptoms occur widely across many conditions, including multiple sclerosis, for which cannabis can be prescribed on the NHS. Although MS is a different condition to CRPS, there are some crossover symptoms so the studies here may be used for context. Large clinical trials and reviews, alongside much anecdotal evidence, have found cannabis to improve muscle spasticity and pain in MS patients. Likewise, numerous studies have found that treatment with THC, CBD and other cannabinoids can help people fall asleep faster and stay asleep longer; however, high-dose chronic use of cannabis may have the opposite effect, while also suppressing REM sleep.
For the best results on pain, sleep, muscle spasms and mobility, cannabis products should be used under close clinical supervision with dose guidance.
CBD and THC for CRPS, what is the difference?
CBD and THC both interact with the body's endocannabinoid system, and multiple other targets, but in different ways.
While CBD elevates levels of naturally produced endocannabinoids (neurotransmitters which activate the ECS receptors), THC fits like a lock and key into the ECS receptors found in the brain and spinal cord. This results in varying actions – including the psychoactive effect of THC (CBD is not psychoactive).
CBD is best known for its anti-inflammatory and anti-oxidative properties, while THC has been found to help with chronic and nerve pain, easing muscle spasms, reducing nausea and helping with sleep issues short-term. THC also tends to be the cannabinoid with the greatest potential to produce adverse side effects.
Many studies find that CBD and THC are most effective for a wide variety of symptoms when used together, as they work in synergy, producing something called ‘the entourage effect’. CBD has also been found to mitigate some of the undesirable psychoactive effects of THC.
CRPS type 1 and type 2: does the difference matter?
CRPS type 1 (formally known as Reflex Sympathetic Dystrophy) is a form of complex regional pain syndrome triggered by an illness or physical trauma where no specific nerve is damaged.
CRPS type 2 (formally known as Causalgia) develops after a confirmed injury to a specific nerve.
The symptoms and multi-disciplinary treatment options are much the same for both types.
What triggers a CRPS flare?
A CRPS flare can occur as a result of physical stress, environmental changes (such as temperature or barometric pressure) or unusual activity. Other common triggers can include poor sleep, sensory stimuli, medication response or dietary changes. Medical cannabis for CRPS can help with some of the symptoms of a flare, and help reduce the likelihood of a flare by supporting better sleep and relaxation.
How does medical cannabis sit alongside gabapentinoids, antidepressants and opioids?
Medical cannabis can be prescribed as a CRPS treatment alongside other frontline medications such as gabapentinoids, antidepressants and opioids. However, it is vital to only take cannabis with medications under close clinical supervision due to potential interactions and side effects.

Risks, side effects, and who it may not suit
Although medical cannabis treatment in the UK is available as a treatment for many symptoms and conditions, it’s not suitable for everyone. Certain medications cannot be taken alongside medical cannabis, and people with a history of specific mental health and physical conditions might also be advised against it. As with all medicines, cannabis can cause side effects when taken without guidance.
To mitigate risk and side effects, all Releaf patients undergo a rigorous approval process before being prescribed cannabis products.
