Other associations have been made between cannabis use in pregnancy and childhood cognitive development, with studies finding children whose mothers used cannabis in pregnancy had poorer academic achievement and attention.

The research hypothesis is that an early-age nutritional intervention among preschoolers would make a significant impact on physical and cognitive development.
