The overall objective of this proposed project is to prospectively evaluate the epigenetic and developmental effects of paternal cannabis and other drug use in offspring.

This project involves enrollment of 40 healthy mother-father dyads that are between the ages of 18 and 40 years. Urine samples for qualitative drug and cotinine testing will be collected from mother-father dyads, as well as quantitative THC (tetrahydrocannabinol) and THCCOOH (11-nor-9-carboxy-THC) assay. A semen sample will be collected from biological fathers. Relevant birth outcome data including both infant and maternal measures will be extracted from the electronic health record (EHR). Infant developmental assessments will be completed at approximately 6 months of age.
