Smoking ups stroke in men and women

The systematic review and meta- analysis of 81 prospective studies in four million patients showed women who smoked had a similar increased risk to male smokers, compared with non-smokers, giving a pooled relative risk ratio of 6% for overall stroke risk.

The international study led by Professor Rachel Huxley, an epidemiologist at the School of Population Health at the University of Queensland, said previous research showed there was a greater risk of heart disease in female smokers.
