Brief Summary:

Medical marijuana is commonly prescribed people with Multiple Sclerosis (MS) for symptom, e.g. spasticity and pain, management. Unfortunately not much is known about its effects outside the treatment for these 2 symptoms. Several previous studies have suggested people with MS using medical marijuana have lower levels of physical disability and improved walking abilities. A major limitation of these previous studies is that the investigators used subjective measures of motor function. In this proposed observational case-control study the investigators plan to objectively measure multiple domains of motor function, such as: fatigue, strength, and walking ability. No marijuana will be brought on to campus or given to participants.

Condition or disease	Intervention/treatment
Multiple Sclerosis	Behavioral: Medical Marijuana

Detailed Description:

To investigate the effects of medical marijuana usage on physical function the investigators will employ an observational case-control design. Cases (MS medical marijuana users) will be compared to age, sex, and disease duration matched controls (MS non-cannabis users).

Primary Outcome Measures :

1. Fatigue [ Time Frame: Through study completion, an average of 6 months. ]
   Strength decline during fatiguing muscle contraction measured with force transducer
2. Muscle Strength [ Time Frame: Through study completion, an average of 6 months. ]
   Maximal muscle strength measured with force transducer
3. Postural Stability [ Time Frame: Through study completion, an average of 6 months. ]
   Measured with force plates
