Multiple Sclerosis Multiple Sclerosis disrupts the normal functioning of the brain and spinal cord nerves. Since the central nervous system controls the entire body, the effects may appear anywhere. Debilitating attacks, which can last for weeks, come and go unpredictably. There is a gradual deterioration in health and increasing disability. Common symptoms include tingling, numbness, impaired vision, speech defects, painful muscle spasms, loss of co-ordination, loss of balance, fatigue, weakness, paralysis, loss of bladder control, urinary tract infections, constipation, skin ulcerations and severe depression. There is no one cure or treatment for MS, only a barrage of drugs to treat the individual symptoms. The standard drugs used to treat muscle spasms are addictive and have severe side effects. For many sufferers, these drugs don’t even have any beneficial effects. Cannabis has a profound effect on the symptoms of MS. It can control muscle spasms, reduce tremors, and restore balance, co-ordination, bladder control, speech and even eyesight.
