Between 5 -26% of smoking women will continue to smoke during pregnancy
Maternal tobacco use exposes the fetus to more than 7000 chemicals, including nicotine, known carcinogens and toxic heavy metals
Major risk of cardiovascular and respiratory diseases, cancer, diabetes, and a host of other illnesses

Nicotine is linked directly to growth and neural development deficiencies, which have long-term effects on brain function, cognition, and behavior. Prenatal nicotine exposure increases the risk of a wide range of behavioural and developmental problems, including attention deficit hyperactivity disorder,conduct disorders,externalising behaviour problems,and adolescent tobacco use.

What Happens...

When a pregnant person smokes or is exposed to secondhand smoke, nicotine and other harmful chemicals can negatively effect the placenta in several ways, leading to fetal growth restriction or low birth weight

After crossing the placenta, nicotine concentrates in the fetal tissue
The direct effects of nicotine predict deficits in growth and neural development, which have long-term effects on brain function, cognition, and behavior. Indirectly, nicotine affects size through placental pathology

How Nicotine Effects Placenta

juliabrinn — 2024-12-13 06:46:37 UTC

Nicotine restricts blood flow to the placenta and causes Vasoconstriction: narrowing of the blood vessels
Increased risk of Placental Abruption: where the placenta prematurely detaches from the uterine wall
Structural and functional abnormalities in the placenta: including changes in placental size and shape
Damage to placental villi (small projections that exchange nutrients and gases)
Nicotine and its metabolites can reduce the efficiency of the placenta in nutrient and oxygen exchange

premature birth and low birth weight (LBW)
damage to developing organs e.g. lungs and brain
doubles risk of abnormal bleeding during pregnancy
birth defects such as cleft lips and palate
higher risk of SIDS

Feeding difficulties

Breathing problems after birth that last into childhood
Cerebral palsy
Developmental delays (language, thinking, or movement skills)
Problems with hearing or eyesight

Women who quit smoking by the third trimester are not at an increased risk for having a newborn with a low birthweight, but women who begin smoking in the late second or third trimester have a risk of low birthweight equal to women who smoke during the entire pregnancy.

Quitting smoking during the first trimester, especially before 16 weeks of pregnancy, produces neonates (infants less than 28 days) with anthropometric measures (used to assess the size, proportions and composition of the human body) similar to women who never smoked.
