Brief Summary
The purpose of this study is to learn if the use of inhaled cannabis (marijuana) and oral cannabinoid (dronabinol, Marinol or THC, which is an active ingredient of marijuana) is safe and effective in reducing the symptoms of spasticity and tremor in patients with secondary-progressive or primary progressive multiple sclerosis.

Outcome Measures
Primary Outcomes (4)
Change From Week 0 to Week 3 in the Rate of Torque Increase, Flexion
A modified servo-controlled torque motor system (Lido WorkSet II) was designed for this study to analyze the resistance to passive movement of the knee. It determines the amount of torque required to move the knee joint (without voluntary resistance) at high velocities (up to 200 degrees per second) and at slow velocities (as low as 10 degrees per second). The slow displacement torque is a measure of the passive resistance to movement (from the connective tissue and the non-contracting muscle) and the rapid displacement torques are the sum of the passive and active (involuntary) resistance. The active (involuntary) resistance is the result of the stretch reflex and correlates well with the clinical assessment of spasticity. The change was calculated by taking the value at Week 3 and subtracting the value at Week 0. A negative result indicates a decrease in the torque measured and correlates to a decrease in spasticity and a better outcome.
