Drugs and Pregnancy

On This Page

Using drugs or drinking alcohol while pregnant can create a number of health issues for both mother and child. An increased risk of stillbirth and miscarriage serve as two of the more stark examples of the potential outcomes faced by pregnant women already struggling with debilitating substance abuse.

Despite the negative consequences, many continue to use substances. In fact, almost 10% of pregnant women in the U.S. reported drinking alcohol from 2012-20132 and, though much of it is done to manage other health conditions, it’s increasingly more common for women to continue using medications while carrying a child.3 There’s been a 60% increase (in 30 years) in the number of women taking prescription medications during the first trimester and it’s currently reported that 9 out of 10 pregnant women take at least one medication.3

An increased risk of stillbirth and miscarriage serve as two of the more stark examples of the potential outcomes faced by pregnant women already struggling with debilitating substance abuse.

Effects of Taking Drugs While Pregnant


Even a small amount of alcohol consumed during pregnancy can place an unborn baby at risk, according to the National Institute on Alcohol Abuse and Alcoholism.

Drinking alcohol can increase your risk of miscarriage and may result in a number of development issues in your child like fetal alcohol syndrome (FAS)—the most severe example on the spectrum of fetal alcohol disorders.4 All fetal alcohol spectrum disorders involve negative consequences affecting the physical, mental, and behavioral health of your child—effects that can last a lifetime.4

Though there is no safe level of alcohol consumption, many pregnant women consume at least some alcohol during this time, believing that a small number of drinks will be safe. In fact, half a million children are exposed to alcohol in utero each year.1

Cigarettes contain harmful chemicals that can damage a developing baby’s brain and can limit the amount of oxygen being received by the fetus. Also, the impact of nicotine on a developing baby is greater than the impact on the mother. According to the National Institute on Drug Abuse, nicotine concentration is up to 15% higher in the baby’s blood than the mother’s.5

Exposing your unborn baby to the tar, nicotine, and carbon monoxide in cigarette smoke can also result in a number of health issues after birth, including respiratory issues, cerebral palsy, and problems with eyesight and hearing.

Sadly, not smoking yourself does not entirely guarantee your child’s safety. Even being around others that smoke can affect your child, resulting in a lower birth weight, increased likelihood of developing a respiratory illness, and a higher risk of sudden infant death syndrome (SIDS).4


Tracking the negative effects of cocaine use during pregnancy is a difficult task, mostly because women that abuse cocaine will often have poor nutrition and inadequate prenatal care. Cocaine users also tend to use the drug in combination with other substances like alcohol, making it hard to determine precisely which substance is responsible for the harmful effects on the fetus.5

It is known that cocaine exaggerates the normal cardiovascular changes you experience during pregnancy.5 Women consuming the drug are risking the development of severe hypertension, seizures, migraines, and separation of the placenta from the uterus, which puts a mother’s ability to carry her baby to term in jeopardy.5

Your child may also be at increased risk of seizures, increased blood pressure, cardiac arrhythmia, and sudden death.


If you use heroin while pregnant, you increase the chance of bleeding, especially during your third trimester, as well as preeclampsia (severe high blood pressure).1 You’re also putting your developing fetus at risk of a premature birth, dangerously low birth weight, and death. Using an illicit drug like heroin also significantly increases your baby’s risk of developing neonatal abstinence syndrome shortly after birth as well as sudden infant death syndrome (SIDS), also referred to as crib death.

Your baby is also likely to experience neonatal abstinence syndrome (NAS) after birth if continually exposed to heroin in-utero.1 NAS is a postnatal withdrawal syndrome that impacts the infant with effects including irritability, excessive crying, breathing problems, gastrointestinal problems, and feeding issues.1 NAS requires intensive medical attention.5


Contrary to popular belief, marijuana can be harmful and should be avoided when trying to conceive, during pregnancy, and while breastfeeding.1,5 While there is limited evidence on how marijuana use can affect a developing fetus, several studies suggest that its use may be associated with impaired fetal development, rare forms of cancer, premature birth, and low body weight at birth.

Marijuana use during pregnancy may be linked to problems such as inattention, impaired decision-making skills, and poor academic performance.1

MDMA (Ecstasy)

Studies suggest that fetal MDMA exposure during the first trimester can lead to long-term memory problems and impaired learning, as well as movement and coordination problems in the child.5 There have also been cases where babies exposed to MDMA while in utero developed cardiovascular anomalies and musculoskeletal problems.


It has been reported that exposing a fetus to meth can result in several long-term health issues, including issues with cognitive skills, physical dexterity, and behavior. Mental health problems including increased depression, anxiety, and social isolation have been reported in children exposed to meth in the womb.5 Some studies also suggest that meth use during pregnancy may be associated with congenital abnormalities, such as gastroschisis—a structural defect that can result in a baby being born with their intestines outside of the abdominal wall.

Pregnant women using meth are at risk of high blood pressure, placental abruption, and premature delivery.5

Painkiller use during pregnancy, even if these medications were prescribed by your doctor before conception, can be harmful to your developing fetus. Opioid painkiller exposure to a fetus may be linked to excessive fluid in your baby’s brain, abdominal wall defects, glaucoma, and congenital heart defects.

Since many painkillers are chemically similar to heroin, the mother and child can experience many of the same risks. Children may be born with NAS, experiencing painful withdrawal symptoms after birth.

Treatment for Drug Addiction

If you’re addicted to drugs or alcohol either before you get pregnant or during your pregnancy, there is help available. Getting help as early as possible will increase your chances of having a healthy baby and staying healthy and safe yourself.

You have a number of treatment options to choose from. Each option represents a unique set of interventions provided in settings that range in intensity and duration. The best treatments will address your addiction, mental health, physical health, and reproductive status.6

The first step towards treatment for many is detoxification and medically managed withdrawal.6 During this process, a team of medical professionals will monitor your vitals and administer medications as needed to add comfort and safety to you and your child while the substance leaves your body.6 Depending on the drug used and the severity of addiction, you can detox in one of a variety of settings, described below.6-8


This includes all facilities that require the person to live at the center during treatment. These options are generally the most intensive forms of treatment, as they provide 24-hour care, supervision, and structure. Inpatient/residential settings can be a specialized unit in a hospital environment or a facility that closely resembles a home.

Inpatient/residential treatment options can last for days, weeks, or months to assist you as you recover and get as healthy as possible for your child.


This includes all programs that allow the person to live at home during treatment. Outpatient treatments provide a relatively lower intensity of care, which is appropriate for people with strong community support or those that have previously completed a more rigorous program. Like inpatient/residential programs, outpatient treatments can take several forms:

  • Partial hospitalization programs (PHPs) that offer care 5 days per week for about 6 hours each day (the highest level of outpatient care).
  • Intensive outpatient programs (IOPs) that provide about 10 hours of weekly treatment divided over 2 or 3 days.
  • Standard outpatient that usually includes weekly therapy sessions lasting approximately an hour.

Both inpatient and outpatient treatments can offer individual, group, and family therapy using techniques like:1,6,7

  • Contingency management (CM)—Attempts to offer positive reinforcement and desired rewards to encourage sobriety and healthy behaviors.
  • Motivational interviewing (MI)Strives to build the desire for change within the person by resolving doubt and uncertainty.
  • Cognitive behavioral therapy (CBT)Works to identify the thoughts, feelings, and behaviors that result in substance abuse before learning coping skills to change old patterns.

Treatments may include medication management options beyond those used during detoxification.6 For example, methadone (a prescription opioid medication used to limit withdrawal and reduce cravings for opioids) paired with behavioral therapies and strong prenatal care can reduce harm to the mother and baby.6 Though this treatment is used in practice, it should be noted that there are no federally approved opioid treatment medications for pregnant women.6

When you begin the process of recovery, a treatment support advisor will let you know which option is the best choice for you once they assess your situation. You may even be able to find a rehab center that specializes in substance abuse among pregnant women.

Professional addiction treatment options, like the ones listed above, all share the ability to improve outcomes for those that decide to begin their journey toward recovery.6

Remember, when you’re carrying a child, it’s not just your own health you need to think about. Give your child the best chance at life by getting clean and sober once and for all.
