The Our World in Data page Smoking by max Roser and Hannah Ritchie has 19 graph, with data, related to smoking. In general, men smoke more than women except in Nauru (see graph copied here).
Every 5th adult in the world smokes tobacco. But there are large differences between men and women.
More than one-third (35%) of men in the world smoke. Just over 6% of women do. Here is the data for men; here for women.
We see that almost all countries lie above the grey line, meaning a higher share of men smoke. But there are a few exceptions: in the Pacific island-state of Nauru 43% of women smoke compared to 37% of men; and smoking rates in Denmark and Sweden show almost no sex difference.
