Pregnancy and Smoking

Recent research in the patterns of brain development has shown a strong relationship between prenatal conditions and future development of abnormalities in youth.  Not all abnormalities that develop over a lifetime are the result of prenatal negligence, but many abnormalities seem to have a connection with complications during gestation.  One of the most dangerous behaviors an expecting mother can engage in is exposing her fetus to any of the thousands of chemicals in cigarette smoke, either directly or through secondhand smoke.

  • Roughly 22% of women in the United States use tobacco products and as many as 13-22% of them smoke while pregnant.1
  • Since the fetus’s circulatory system is in part regulated by the mother’s body, anything inhaled by the mother and carried through her bloodstream has direct access to the baby.  These toxins will:2
    • Decrease amount of oxygen the baby receives
    • Increase the baby’s heart rate
    • Increase the baby’s risk of developing respiratory complications
    • Increase the risk of premature birth or miscarriage

Smoking and the Baby

In this video, a former smoker describes her experience having her daughter prematurely.

Due to the high rate of development during pregnancy and childhood development, the baby is highly sensitive to these toxins as slight chemical deviations could significantly alter development.  Smoking while pregnant increases the baby’s risks to a number of complications during development including: 2,3

  • Low birth weight
  • Premature birth
  • Multiple placental problems
  • Death

Smoking while pregnant also increases risk of complications following childbirth including:3

  • Childhood obesity
  • Ear infections
  • Respiratory infections
  • Poor learning skills
  • Problems processing sound
  • Decreased cognitive abilities
  • Asthma
  • Withdrawal symptoms
  • Sudden Infant Death Syndrome (SIDS)

Smoking and the Mother

The risks to the baby during and after the pregnancy are the result of exposure to lethal levels of carbon monoxide, toxicity from the roughly 4,000 chemicals in cigarette smoke, damage to genetic material and significantly decreased amounts of oxygen that reach the baby’s brain during development.3,4,5  These are all risk factors that ultimately explain why babies born to smokers are almost 60% more likely to die as infants than babies born to nonsmokers.1  These problems are not limited to being a consequence of just direct smoke, as research shows that exposure to secondhand smoke is equally as detrimental to the baby’s health during development.2  As alarming as these conditions are, the focus should not solely be on the infant, but also the mother as smoking also puts her at risk for many additional complications including:3,4,

  • Menstrual irregularities
  • Infertility
  • Ectopic pregnancy
  • Miscarriage
  • Decrease of breast milk by 50%
  • Decrease of calories and fat available in remaining breast milk by 40%

Cigarette smoking is extremely harmful to both the mother and child as the negative effects can be seen long before fertilization and long after childbirth. Cessation rates in pregnant women are as high as 85%, which is likely due to education around such varied and profound negative effects of smoking.5  Women who continue to smoke during pregnancy are likely to be:4,5,6

  • White (non-Hispanic)
  • Low socioeconomic status
  • Between 15-19 years old
  • Minimal education (less than high school degree)
  • Did not plan pregnancy
  • Overwhelmed by external stresses (e.g., familial, financial, social, etc.)
  • Low health literacy/high health literacy

Unfortunately, quitting mainly for the sake of the baby’s growth during gestation seems to be related to neglecting the other ways in which cigarette smoke can affect the baby’s health after birth.  As a result, these women have extremely high rates of relapse at 50-80% within 6 months after giving birth and 60-90% within the first year.1,2,4,5   Characteristics of women who relapse and remain abstinent, respectively, are:2,5

Characteristics of mothers who…


Remain Abstinent

  • Young
  • Single
  • Low education
  • Heavy Smoker
  • Quit late into pregnancy
  • Low health literacy 
  • Unplanned pregnancy
  • Alcohol consumption
  • Does not take folic acid
  • Middle-aged
  • Married
  • High education
  • Light to moderate smoker
  • Quit before or early into the pregnancy
  • High health literacy
  • Planned pregnancy
  • No alcohol consumption
  • Takes folic acid


Treatment Considerations for a Pregnant Woman

Smoking any tobacco product in any amount has both short-term and long-term detrimental effects and smoking particularly during the second or third trimesters is especially harmful to the baby.4  The more cigarettes a pregnant woman smokes per day, the greater her baby's chances of developing health problems.  There is no "safe" level of smoking while pregnant.

The timing of the mother's decision to quit is just as important as the health of the baby.  Essentially, the sooner the mother quits, the more likely her baby is going to be born without tobacco-related health complications. 

Simply getting the message out is the first step towards a healthier future.  A decline in the percentage rate of pregnant smokers by only one point would save over $20 million worth of medical services and would prevent 1,300 cases of low birth weight each year.2

Use of pharmacological interventions such as gum, pills or patches must be considered carefully as nicotine has adverse effects on the baby’s development despite the absence of tobacco’s numerous other chemicals.5  As a result, behavioral techniques are the most ideal as they are associated with the least amount of side effects.5

Treatment Considerations following Birth

Many reasons have been provided regarding the decision to relapse back into smoking, such as…

  • A desire for weight loss, which was consistently seen across studies as one of the more common reasons to begin smoking again.4,7,8
  • Reducing stress.7,8
  • Providing a break in the day.7,8
  • Alleviating boredom.7,8
  • Providing a way to socialize with friends.7,8

Factors that may help counteract relapse and help mothers remain abstinent:

  • Breastfeeding the child routinely following birth.
    • Breastfeeding is not only beneficial for the mother’s weight loss, but also for the baby’s health as well as the health of the mother’s breast.1
    • Unfortunately, women who smoke are significantly less likely to breastfeed their baby than women who do not smoke.4,7,8
  • Having a strong social network. 4,7,8


Smoke Free Families Smoke-Free Families is a national program supported by The Robert Wood Johnson Foundation working to discover the best ways to help pregnant smokers quit, and spread the word about effective, evidence-based treatments.

Smoke Free Women As a part of the National Cancer Institute's smoke free initiative, this site provides information and tools that specifically address women’s experiences as they become smoke-free. Information, resources, and support to help smokers quit -- wherever they are on their quit journey -- are available.
