Smoking cigarettes constricts blood vessels and reduces blood flow to the placenta, which can decrease the amount of oxygen and nutrients that reach the developing fetus. This can lead to growth problems, preterm delivery, and other complications. Consuming alcohol can also affect placental development, but it is not the best choice here as it is not specifically related to reduced blood flow.
