Female significantly likely be lifetime nonsmokers cigarettes male (23% 3.7%, Among current smokers, women started smoking older (19.3 0.69 16.5 0.21 smoked fewer (41.0 1.2 47.4 0.57 0.001) slightly per day (23.6 1.0 26.7 0.63, 0.05). Similar results found duration habit number among exsmokers. When smokers exsmokers combined, distribution pack by gender different.
