Data from three prospective longitudinal human cohorts of prenatal marijuana exposure and offspring outcomes from the fetal period through young adulthood.

This article includes data from three prospective longitudinal human cohorts of prenatal marijuana exposure (PME) and offspring outcomes from the fetal period through young adulthood. The table herein contains an overview of the major adverse effects associated with PME from the following human cohorts: (1) The Ottawa Prenatal Prospective Study (OPPS); (2) The Maternal Health Practices and Child Development Study (MHPCD); and (3) The Generation R Study (Gen R). In the OPPS, fetal gestational age was measured and age-appropriate standardized neuropsychological instruments were used to assess neonatal responses, and infant-child and adolescent-young adult cognitive and behavioral skills. In the MHPCD, birth length and weight, neonatal body length, and infant-child sleep, cognition, and behavioral parameters were measured. In the Gen R, birth weight and growth were measured, as were infant-child attention and aggression. The data in this article are in support of our report entitled "Prenatal Cannabis Exposure - The "First Hit" to the Endocannabinoid System" (K.A. Richardson, A.K. Hester, G.L. McLemore, 2016) [13].
