The results weren’t pretty.
It’s no secret that a mother’s health choices while pregnant have a significant impact on her baby. Recent research has found that drinking during pregnancy increases the risk of alcoholism in the next three generations, and if the mother is obese, the baby is 4 times more likely to be autistic.
Now, researchers have looked into the effects of alcohol, marijuana, and methamphetamine exposure on the human placenta. Animal studies have revealed some of the undesirable effects of prenatal alcohol exposure (PAE) on placental development, but few studies have looked at these effects in our own species. This is the first-ever study to investigate the effects of prenatal exposure to meth, marijuana, and cigarettes on human placental development.
