Hello. According American Academy of Neurology, studies showed that medical marijuana can help treat certain Multiple Sclerosis symptoms such as spasticity or chronic muscle tightness. Medical Marijuana may also help lessen central pain (feelings of painful burning, pins and needles, and numbness) and help lessen frequent urination. According to the American Epilepsy Society, studies suggest that Cannabidiol (CBD) may improve overall quality of life, epilepsy, and comorbidities associated with epilepsy. Medical marijuana may treat neurological conditions such as amyotrophic lateral sclerosis (ALS), Parkinson's disease, multiple sclerosis, spinal cord injury with objective neurological indication of intractable spasticity, epilepsy, and neuropathy.
