A new study shows that in Australia, 80% of the women who are pregnant, drink alcohol during their pregnancy. The lack of evidence and unclear risks of drinking while being pregnant has left most women and their partners confused about the effects of alcohol on pregnant women. 
Jennifer Powers of the University of Newcastle said "No-one can say with absolute certainty that it is safe to drink alcohol during pregnancy. At the same time we can't say it is unsafe."
Smoking on the other hand was a sure shot at harming the fetus. Most women do not smoke when they are pregnant as the evidence of the effects of smoking on the unborn child has been proven and are dangerous to the baby. Experts say high consumption of alcohol is likely to cause Foetal Alcohol Syndrome which hinders the mental and physical growth of the baby.
The facts about the "large group of women who drink alcohol at low to moderate levels" while they are pregnant is still unknown. The study shows that "about 80 per cent of women consumed alcohol during pregnancy under zero and low alcohol guidelines".
Ms Powers added that it was quite uncommon for women to drink excessively during pregnancy.
