Why is heroine use bad for developing babies?

Heroin use during pregnancy is detrimental to developing babies because it can lead to a range of complications, including low birth weight, premature birth, and neonatal withdrawal syndrome. The drug crosses the placenta, affecting fetal brain development and increasing the risk of cognitive and behavioral issues later in life. Additionally, heroin use can compromise the mother's health, further jeopardizing the baby's well-being. Overall, the risks associated with heroin can have lasting impacts on both the mother and child.
