Prenatal substance abuse is a serious public health hazard that has been related to a number of deleterious maternal and foetal outcomes. Tobacco is the most often consumed substance during pregnancy, followed by alcohol, cannabis, and other illegal substances. "Drug babies" are frequently born to drug-addicted moms. These kids have a variety of developmental issues. Studies reveal that consuming drugs during pregnancy, whether legal or illicit, has a direct influence on the foetus. The foetus will be affected if you smoke, drink alcohol, or consume caffeine. If mothers use marijuana or crystal meth while pregnant, the foetus will be affected as well. And if the mother is addicted to cocaine, commonly known as coke, snow, or blow, they're not only jeopardising thier own life, but they're also risking the health of the unborn child. Heart attacks, respiratory failure, strokes, and seizures are all possible side effects of cocaine use. These potentially fatal health issues can also be passed on to an unborn child.
