So, most modern day women stop smoking and drinking when they get pregnant right? But, since you don't find out that you're pregnant until the month after you get pregnant, a smoker or drinker could be causing serious harm to their child without even realizing it, when they would definitely have quit if they had known that they were currently pregnant. Is smoking and drinking while pregnant as dangerous as the after-school specials would have us believe? If so, don't women have a moral obligation to not drink or smoke at all when in a sexual relationship?
