|Study Design:||Allocation: Randomized
Intervention Model: Parallel Assignment

|Official Title:||Cannabis for Spasticity in Multiple Sclerosis: A Placebo-Controlled Study|
- Change in an objective measurement of spasticity between the pretreatment assessment and the 4- and 8-week assessments.
- Differences between active agent and placebo in the changes in Ashworth Scale, Functional System Score, Expanded Disability Status Score, Ambulation Index, Functional Composite Score, and Quality of Life Inventory.

The treatment of MS is far from satisfactory. For acute attacks, high dose corticosteroids seem to reduce the duration of attacks and to reduce the likelihood of future attacks. Immunomodulatory agents, available in this disease over the last decade, reduce the frequency of severe attacks by about one third. The remainder of the treatments are symptomatic, aimed at reducing the disability already present.
Recent research into the CB1 and CB2 cannabinoid receptor systems suggest that cannabis may have the potential for affecting both the pathogenic mechanisms and the symptoms of MS. In light of the autoimmune hypothesis of the etiology of MS, THC could directly alter immune function in a manner that might reduce (or increase) the primary pathology of the disease.
Comparisons: Three treatment arms will be compared: 1) inhaled cannabis and oral placebo, 2) inhaled placebo and oral THC, 3) inhaled placebo and oral placebo, with the effects of these agents analyzed at thirty and sixty days.
