There is a debate about the extent to which the effect of prenatal smoking on infant health outcomes is causal. Poor outcomes could be attributable to mother characteristics which are correlated with smoking. I examine the importance of selection on the effect of prenatal smoking by using three British cohorts where the mothers’ knowledge about the harms of prenatal smoking varied substantially. I find that the effect of smoking on the probability of a low birth weight birth conditional on gestation is slightly more than twice as large in 2000 compared to 1958, implying that selection could explain as much as 50 percent of the current association between smoking and birth outcomes.
