i'll tell you the same thing my obgyn told me about cigarettes and coffee while i was pregnant; you can have them - if you want to. it technically is your choice (your child doesn't yet have the luxury of making one for themselves they have to live with yours). "they" are always looking for statistics to go off of for future reference. it's up to you if you want your child to be used as a statistic or not.
can i smoke e cigarettes while pregnant?
