Medical Cannabis and Multiple Sclerosis

May 24th, 2023 by The Starseed Team

Multiple Sclerosis (MS) is a chronic autoimmune disorder that affects the central nervous system (CNS). MS occurs when the immune system attacks the myelin sheath, which is a protective covering around nerve fibers. This leads to nerve damage, which can cause a range of symptoms, including muscle weakness, spasticity, fatigue, and chronic pain. While there is no cure for MS, there are various treatments available that can help manage symptoms and slow the progression of the disease. One such treatment that has gained attention in recent years is medicinal cannabis.

Medicinal cannabis has been shown to be effective in treating a range of symptoms associated with MS. One of the most significant symptoms of MS is spasticity, which refers to involuntary muscle contractions that can cause stiffness, spasms, and pain. Medicinal cannabis has been found to be effective in reducing spasticity, which can improve mobility and quality of life for MS patients.

In addition to spasticity, medicinal cannabis has also been found to be effective in reducing chronic pain associated with MS. Chronic pain can be debilitating and can impact a person’s ability to carry out daily activities. Medicinal cannabis can help reduce pain and improve overall quality of life for MS patients.

Medicinal cannabis may also be beneficial in reducing fatigue, which is a common symptom of MS. Cannabis can have a stimulating effect that can help increase energy levels and improve mental clarity. This can help MS patients manage fatigue and carry out daily activities.

Sativex is an oral spray formulation of THC and CBD that has been approved by Health Canada and is used to treat conditions like MS and cancer-related pain. It has been approved as an adjuvant therapy for adult MS patients with spasticity who have not responded well to previous treatments. When used together, THC and CBD have been found to have a synergistic effect, meaning that they work better together than they do separately.

While medicinal cannabis may be effective in treating symptoms associated with MS, it is important to note that it is not a cure for the disease. MS is a complex condition, and there is no single treatment that can address all its symptoms. Medicinal cannabis should be use in conjunction with other treatments, such as disease-modifying therapies and physical therapies, to manage symptoms and slow the progression of the disease.

Medicinal cannabis is not without risks and side effects, and it is important to speak with a health care provider before using it as a treatment for MS. Cannabis can have psychoactive effects, and it may interact with other medications.

What is CBG?
CBG (cannabigerol) is a type of cannabinoid derived from the cannabis plant. CBG, like CBD, is non-intoxicating (it does not get you high) and can be used as an alternative or supplement to CBD and THC-based cannabis products. It is known as the "mother of all cannabinoids" and is a remarkably versatile compound with significant therapeutic promise. Here are several areas where CBG has shown potential therapeutic effects in preclinical animal studies: -        Neurological illnesses such as Huntington’s disease (HD), amyotrophic lateral sclerosis (ALS), Parkinson’s disease (PD) and multiple sclerosis (MS) -        Gastrointestinal diseases such as inflammatory bowel disease (IBD) -        Chemotherapy-induced nausea and cachexia -        Antibacterial agent Although this research into CBG has shown promise, there is still much to understand and more research on its efficacy and long-term effects is required. How is CBG used today? A team of American scientists recently examined the perceived therapeutic effects of consuming CBG-dominant products in humans (see Figure 1 below). Anxiety (51.2%), chronic pain (40.9%), depression (33.1%), and insomnia (30.7%) were the most frequent medical conditions reported to show efficacy. In addition, a significant proportion of people reported stopping taking the top three drug classes—antidepressants, non-opioid analgesics, and proton pump inhibitors. The most frequent side effects were dry eyes, dry mouth, sleepiness, and increased appetite. Why is CBG so exciting? Anxiety appears to be one of the most common indications for CBG, with patients reporting benefit. And anxiety can be difficult to treat because some anti-anxiety medications, such as benzodiazepines, are not widely accepted and might have negative health consequences such as addiction, memory loss, etc. Can CBG be an alternative for anxiety? It is certainly a desirable alternative. While preclinical and clinical studies indicate its efficacy in various conditions, further research is necessary to fully understand CBGs therapeutic potential and optimize its use as a medicinal agent.
