Swedish Study

Smoking Increases Risk of MS

Smoking cigarettes increases the risk of multiple sclerosis (MS), but the substance that makes cigarettes addictive, nicotine, doesn't seem to be at fault, Swedish researchers say. While male smokers were 1.8 times as likely to have MS as non-smokers, and MS risk increased 1.4-fold for women who smoked, people who used Swedish snuff were actually less likely to have the disease, Dr. Anna Hedström of the Karolinska Institutet and her colleagues found.
