Almost all drugs pass through the placenta to reach your baby and have some effect on her (Behnke et al 2013) . Drugs in your body may reduce the amount of oxygen that can reach your baby. Early in pregnancy, some drugs may affect your baby's development. Your baby may not grow as well as expected in your uterus (womb) (Behnke et al 2013) . Taking illegal drugs may cause problems later on in your pregnancy, too, as they can affect how well the placenta works. There is a risk that the placenta may come away from the side of your uterus, sometimes causing severe bleeding. This is called placental abruption.
