Why Do Women Smoke?

"Despite global trends indicating an overall decline, cigarette smoking is increasing among women in high-income countries and is highest among women of reproductive age."

The above is from a molecular psychiatry paper. The basic finding was that "that background factors, psychological characteristics and genetic variation in nicotinic cholinergic receptors contribute independently or interactively to smoking initiation and to severity of nicotine dependence in young women." Though that seems obvious, actual data is very important to confirm or disconfirm our intuitions.
