“Associations between cannabis use and offspring DNA methylation have not been investigated; however, maternal tobacco smoking in pregnancy is associated with distinct patterns of DNA methylation at birth and beyond. To determine whether maternal cannabis use is associated with methylation of the dopamine receptor gene DRD4 promoter in infants. There is no strong evidence that maternal cannabis use in pregnancy is associated with offspring DRD4 methylation.”  https://www.ncbi.nlm.nih.gov/pubmed/28448718

“Marijuana use is becoming increasingly common in the obstetric population, however it is unknown whether it is associated with poor neonatal outcomes. We sought to determine the prevalence and risk factors for marijuana use in pregnancy, and to evaluate whether marijuana use is independently associated with poor neonatal outcomes.

CONCLUSION:

Marijuana use is common in pregnancy, but may not be an independent risk factor for poor neonatal outcomes in term pregnancies.”
