4 Harms of Smoking

On one hand, tobacco contains a lot of toxic substances. In addition to the well-known nicotine, there are also hydrocyanic acid, ammonia, carbon monoxide, carbon dioxide, pyridine, aromatic compounds and tar. These substances enter into the mother’s blood with the smoke, reducing the blood content in the mother’s body and the oxygen content in the placenta. Due to the lack of oxygen in the fetus, it can cause growth retardation, resulting in underweight. The baby born is weak. The risk of serious disease within one year of birth and the mortality rate is high.

On the other hand, smoking increases the risk of fetal congenital malformations. Some data shows that the number of congenital malformed children born to smoking mothers is 23 times that of non-smoking mothers. Smokers cause fetal anencephaly, cleft palate, cleft lip, dementia and physical developmental disorders as well as other deformities. These are 2.5 times that of non-smokers.

Moreover, smoking leads to a high incidence of congenital heart disease in infants born. The effects of smoking on the fetus are very large. Studies have found that typical carcinogens derived from tobacco are found in the urine of children born to smoking women. The fetus absorbs nicotine through the umbilical cord and converts it into carcinogens in the liver. Finally the fetus excretes it through the kidneys, which damages the liver, kidneys and lungs of the fetus.

Last but not least, smoking by pregnant women will also accelerates the fetal heart rate and reduce the breathing movement. The nicotine and other toxic substances in the smoke can also penetrate into the placenta through the blood. Then it transport to the fetus and even cause damage to the imperfect organs.
