Could my growth be stunted by exposure to dad's cigarette smoke?

Maybe. I don't think that has been studied specifically, but recent research has demonstrated that children get approximately 1/3rd of passive indoor smoke. That means if parents (or others) smoke a pack a day in the house or car, the children living there are smoking a third of a pack a day. The harmful effects of smoke are even more profound and various in infants & growing children than in adults.
