Overall, those children who were exposed to cocaine during pregnancy had lower scores on the Short Term Memory scale than unexposed children at all age levels, especially boys. Cocaine exposure also predicted lower IQ scores in general. [32] Exposing prenatal offspring to cocaine can cause irreversible damage and increase developmental risks. [32]
