A Comprehensive Guide to Medical Cannabis for Multiple Sclerosis (MS)
Although cannabis remains classified as a Class B controlled drug under the Misuse of Drugs Act 1971, significant changes were made in November 2018 regarding its medical use in the UK. After years of lobbying by advocacy groups, doctors, and researchers, medicinal cannabis was made available on prescription for certain conditions, including multiple sclerosis (MS).
Multiple sclerosis (MS) is a neurological condition affecting the central nervous system, including the brain, spinal cord, and optic nerves, and can lead to varying degrees of disability. The symptoms of MS vary but may include:
-
Weakness or numbness in the limbs, often affecting one side of the body
-
Muscle spasms or stiffness
-
Bladder control issues
-
Problems with coordination and balance
-
Vision problems, such as blurred vision or partial loss
-
Difficulty walking
-
Cognitive issues, such as memory lapses
MS symptoms typically follow a relapsing-remitting pattern, where periods of symptom flare-ups are followed by periods of remission. The duration and severity of these episodes can vary greatly from person to person.
While more research is needed, existing clinical studies and anecdotal evidence suggest that medicinal cannabis may help alleviate some MS symptoms.
Cannabis, Multiple Sclerosis, and the Endocannabinoid System
Cannabis contains compounds called phytocannabinoids, which interact with the body’s endocannabinoid system (ECS). The ECS is a network of receptors located throughout the brain, central nervous system, and peripheral nervous system. These receptors, when activated by cannabinoids, regulate processes such as pain, memory, appetite, and inflammation.
The two main cannabinoids in cannabis—THC and CBD—show promise in treating MS symptoms, particularly muscle spasms and pain. Some studies suggest cannabinoids may provide relief, with one report noting an improvement in mobility and pain perception. Another study concluded that cannabinoids could be a useful therapeutic option, especially given that current MS treatments have side effects that some patients find intolerable.
Preliminary research suggests that THC could help reduce muscle stiffness and spasms. In one study, MS patients who took THC reported significant improvements in these symptoms over a four-month period.
Additionally, cannabis may have neuroprotective properties, potentially protecting nerve cells from damage—a major cause of MS. However, more research is needed to fully understand how effective cannabis may be in treating neurodegenerative diseases.
Risks and Side Effects of Medical Cannabis for MS
As with any treatment, medicinal cannabis carries potential risks and side effects. These may include short-term effects such as dizziness, headaches, and confusion, as well as possible long-term risks like dependency (though rare) and increased anxiety or depression.
Moreover, cannabis can interact with other medications, so it’s crucial to consult a doctor before incorporating it into your treatment plan.
Forms of Cannabis for MS Treatment
Currently, the only approved cannabis-based treatment for MS in the UK is Sativex, an oral spray containing equal amounts of THC and CBD. Sativex is primarily prescribed for treating muscle stiffness and spasms in MS patients, but some have reported additional benefits, such as improved sleep and reduced pain.
Other Cannabis Products for MS
Products containing both THC and CBD may be beneficial in managing MS symptoms. Various forms, including edibles, topical creams, and vaporised cannabis, are available, though they are not as widely approved as Sativex. Many patients have reported positive effects from balanced THC/CBD products.
Legal and Ethical Considerations
In the UK, many MS patients have resorted to obtaining cannabis from illicit sources to manage their symptoms. This poses legal risks and highlights the ongoing stigma around cannabis for medicinal purposes. Although the medicinal cannabis industry is slowly growing, there remains some hesitancy and misunderstanding surrounding its use.
As research progresses and awareness increases, it is hoped that medicinal cannabis will gain wider acceptance as a legitimate treatment option. However, it’s important for patients to discuss any potential treatments with a healthcare professional licensed to prescribe cannabis-based products.
Conclusion
Cannabis has been used as a medicinal treatment for centuries, and recent studies suggest that it may offer relief for multiple sclerosis sufferers. Both THC and CBD have shown potential in reducing muscle stiffness and pain in preliminary studies, and there is evidence suggesting cannabis may protect against nerve damage.
While more research is necessary to confirm its efficacy in treating MS, anecdotal evidence and initial studies are encouraging. It’s essential for patients to understand the possible risks and side effects before deciding to use medical cannabis as part of their treatment plan. Always consult a qualified healthcare provider before making any changes.
