Cyn - Just thought it was an interesting article. IMHO, I don't think it causes MS as more people would have MS. But I do know that smoking effects the CNS and it makes sense that it would contribute to MS progression. Hence, the reason I posted the article.

It does mention 2nd hand smoke which I thought was interesting as well. In my case, my mom smoked some when we were little. However, if this article were correct, my 9 brothers and sisters would have MS as well.

Again, I think it all goes back to a certain trigger and I think each of may have had a different trigger or combination of triggers.
