Smoking habits in women

Recently came across a video related to smoking habits of women in India by Nikita Thakur, and was actually curious to know how many women are regular smokers. Considering there are lots of health hazards related to smoking, generally do women smokers find it easy to let go of smoking, and at what age do they realize they did a mistake? Also, its important to note that women are more likely to face health problems (about 25% more than men).

PS: Sorry if it seemed I am attacking only women, I am addressing women as this thread is for them; but otherwise I even encourage my male friends to quit smoking (sometimes even abuse them too when its excessive). Its absolutely true smoking is harmful for both the genders.
