According to the new study which assessed the stroke risk in women 15 to 49 years who were smokers, current smokers were 2.6 times as likely to have a stroke than women who never smoked.
Researchers give clear examples, saying women who smoke 21 to 39 cigarettes a day are at more than 4 times the of stroke than a nonsmoker, while those who smoke at least two packs a day, 40 cigarettes, have a stroke risk more than 9 times higher.
