Kratom Use Among Pregnant and Lactating Individuals With Substance Use Disorder

Kratom ( Mitragyna speciosa ) use in pregnancy is associated with maternal and neonatal opioid withdrawal syndrome. However, kratom use patterns in the population of peripartum and postpartum individuals with substance use disorder (SUD) are unknown. The aim of this study was to determine the proportion of pregnant and postpartum individuals with SUD who report using kratom in pregnancy or lactation and the reasons for their use.

We conducted an anonymous survey of pregnant and postpartum individuals receiving care at a single center's multidisciplinary prenatal clinic for individuals with SUD. We collected participants' demographic and pregnancy characteristics. We assessed ever use of kratom, kratom use during pregnancy or lactation, and reasons for kratom use. Descriptive statistics were used to summarize the data.

From January 2021 to May 2021, a total of 80 surveys were collected (81% response rate of 98 eligible individuals). Most respondents were pregnant (n = 50 [62.5%]). The most frequent substance(s) of use were opioids (n = 50 [62.5%]) and methamphetamine (n = 39 [48.8%]). Many (n = 26 [32.5%]) reported ever use of kratom use. Of all respondents, 4 (5%) reported use during pregnancy, and 1 (1%) reported use during lactation. Kratom was primarily used to relieve opioid withdrawal symptoms and for relaxation, pain control, and stress relief.

In a survey of pregnant and postpartum individuals with SUD at a single high-risk pregnancy clinic, ever use of kratom was frequent, whereas peripartum use was rare.
