Are you am MSer who smokes? You might want to reconsider that because Smoking Worsens MS by increasing brain tissue shrinkage. according to the Buffalo Neuroimaging Analysis Center.
A new study in the Netherlands says there is no correlation between smoking and MS progression.
We know smoking is not good for us, but there is a controversy whether it affects MSers any differently from everyone else. We know it doesn't improve MS, but we cannot agree if it is particularly harmful to MSers. I guess this decision has to be made regardless of MS.
