Consuming alcohol, and drugs during a pregnancy is very dangerous for the unborn baby.
Consuming alcohol, and drugs will harm the unborn baby in many ways which may include:
1) Stillborn births. A stillborn birth is where a fetus passes away in the womb, and the mother gives birth to the baby.
2) Clef pallets.
3) Having a premature baby.
Those are some of the few effects that alcohol, and drugs have on an unborn fetus.
I hope this helps you!
