Interesting issue. They talk about smoking and MS and how those who smoke are most likely to have another immune related disease such as inflammatory bowel disease or Crohn's disease (page 9).

Also, they list the results of their members on disability level and related to treatment and level of disability (or lack of DMD and related as such). Those on Copaxone were less likely to have disability. Those taking Avonex were less well off in regards to disability level. If you get NARCOMS magazine you can see the results yourself on page 11. There are more than 35,000 participants in Narcoms surveys today.

This makes me think I will stay on Copaxone for the long run.
