There have been numerous research studies carried out to assess the effects of using cannabis with multiple sclerosis related pain, spasticity, and bladder symptoms.
The majority of studies included fairly small numbers of individuals with MS and the result procedures differed amongst studies. Nevertheless, reviews of published research studies using cannabis in a pill format have actually shown that using cannabis with multiple sclerosis reduced the signs of discomfort and spasticity in the patients. It’s unclear the effects of smoked, vaped, or other forms of edible consumption has on the symptoms.
The Neuroprotective Potential of Weed for MS
Though research is limited at this time, CBD and medical marijuana have been shown to ease symptoms related to multiple sclerosis, epilepsy and Parkinson’s disease. It was also shown to reduce the progression of Alzheimer’s disease in test-tube and animal studies.
The endocannabinoid system, in conjunction with other neurotransmitters and systems, play a role in managing the neurological system. As such, they also play a role in those with disorders of this system.
Neurologic disorders include, but are not limited to, epilepsy, Alzheimer’s and dementia, as well as the effects of other diseases, including diabetes, multiple sclerosis, and some types of arthritis. There is an understanding among scientific researches that CBD may influence and impact the endocannabinoid system as well as other neurotransmitters, to provide additional benefits in both the diseases and the symptoms of these disorders.
CBD and THC for Multiple Sclerosis
Internationally a product called Sativex, an oral spray that includes both CBD and THC, has already been approved and is in wide use for the treatment of muscle spasticity in those patients suffering from multiple sclerosis. While not currently approved in the United States, the research has shown promise that in addition to this use, the results have prompted researchers to further review the impact of CBD on other neurological disorders, with the highest interest and research being conducted on both multiple sclerosis and epilepsy.
- One study found that Sativex reduced spasms in 75% of 276 people with multiple sclerosis who were experiencing muscle spasticity that was resistant to medications.
- Another study gave 214 people with severe epilepsy 0.9–2.3 grams of CBD oil per pound (2–5 g/kg) of body weight. Their seizures reduced by a median of 36.5%.
- One more study found that CBD oil significantly reduced seizure activity in children with Dravet syndrome, a complex childhood epilepsy disorder, compared to a placebo.
Despite the promising outcomes, there have been several side effects that have been associated with the treatment in these vulnerable patients, including fever, fatigue, and more severely, convulsions. Further studies are required to understand the relationship of the underlying disorders and the side effects, but the progress is promising.
