Hey Zeller-
Many MSers go prematurely gray, my husband included. Sometimes nutritional or hormonal deficits can cause it. Never heard of copaxone bringing on the gray...
Dr. Lawrence Wood, the head of the Thyroid Foundation of America, recommends that women who start going gray before the age of 30 should be checked for a variety of auto-immune disorders. According to Wood, "juvenile (Type 1) diabetes, rheumatoid arthritis, multiple sclerosis, colitis and hypothyroidism are all conditions that may track with premature graying."

My hubby takes glisodin and lots of antioxidant nutritional supplements (see Cheerleader's regimen), and his graying has slowed down...he's salt and pepper now.
best of luck,
