Cocaine Use and Birth Defects
"Our data are from one of the first population-based studies in which trends for defects potentially caused by maternal cocaine use are examined; the results of our study show no significant change in the prevalence of multiple vascular disruption defects over time. We suspect that if cocaine is a teratogen, its teratogenicity is weak or is associated with a small subset of birth defects that are yet to be identified."
