Nicotine may protect against the development of multiple sclerosis, according to researchers from the Institute of Environmental Medicine at the Karolinska Institutet in Sweden. In looking for possible causes and risk factors involved in developing MS, a group of researchers in Sweden have examined several possibilities, including smoking and nicotine use.
In a recent study published online, ahead of print, in the journal
Multiple Sclerosis, researchers aimed to investigate the influence of
