The criminalization of abortion in some states after the U.S. Supreme Court's Dobbs decision poses especially harmful health and economic consequences for pregnant women from vulnerable populations, including Black, Latinx, or Indigenous people and those living in poverty. But often overlooked among those likely to be hardest hit: pregnant women with substance use disorders.

Banning abortion could exacerbate already dire situations. Why? There are significantly higher rates of unintended pregnancy among women with substance use disorders (e.g., opioid use disorder). Once pregnant, they have increased risk of severe illness and death around the time of childbirth. And their risk of fatal overdoses increases in the year after childbirth.

This group is also twice as likely to suffer from chronic illnesses such as heart and kidney disease, gestational diabetes, and mental illness—all of which present immediate danger to both the mother and fetus during a pregnancy.

By forcing more women to continue pregnancies, abortion bans also could make it harder for them to get treatment for substance use disorders. Pregnant women already struggle to find affordable, evidence-based, and nonjudgmental care. For example, the standard of care for opioid use disorder is medication—either buprenorphine or methadone. But a 2020 study found that only 61 percent of pregnant women could get an appointment with a provider who would prescribe buprenorphine, compared with 74 percent of women who weren't pregnant.

The United States has a long history of judging and condemning people for prenatal substance use. Many states consider substance use by those who are pregnant to be child abuse or neglect. Others have even proposed or passed laws making it a criminal offense.

The intent of these policies is to decrease the number of infants exposed to illicit substances before birth. But our research shows they may have the opposite effect: The odds of a child being born with neonatal opioid withdrawal syndrome are actually higher in states with punitive policies. Furthermore, punitive policies have been found to deter women from prenatal care and substance use disorder treatment.

Conversely, a recent study found that supportive policies, such as prioritizing pregnant women for substance use disorder treatment, led to a 45 percent increase in evidence-based care. And yet in states that criminalized substance use in pregnancy, the opposite was true: Fewer got treatment and opioid overdoses among pregnant women increased by 45 percent.
