The risk of developing multiple sclerosis (MS) among heavy or regular smokers is about twice that of nonsmokers, according to Alberto Ascherio, professor of epidemiology and nutrition at Harvard T.H. Chan School of Public Health.
“The data on risk are quite compelling,” said Ascherio in a short video interview on the AJMC (American Journal of Managed Care) website.
He also noted that smoking can affect MS progression.
