Marijuana and Pregnancy: marijuana-exposed children

Research has shown that infants exposed to marijuana in uterus display altered responses to visual stimuli and increased tremulousness, which may indicate problems with neurological development. Other studies have shown that during infancy and preschool years, marijuana-exposed children have more behavioral problems than non-exposed children. Research also shows that marijuana-exposed children perform visual perception, sustained attention, language comprehension, and memory tasks more poorly when compared with unexposed children.
