Electronic cigarette (e-cig) use in pregnancy is common, but potential effects on fetal development are largely unknown. This study's goal was to examine the association between e-cig exposure and fetal growth. Data were extracted from medical charts in this single-site retrospective study.

Goal: To examine whether fetal growth effects following exposure to tobacco are evident in the second trimester, specific to certain growth parameters, and dose dependent.
Methods: Participants were pregnant women (64 smokers, 100 controls) with no other drug use.
Background: With recent changes in tobacco and marijuana use patterns, it becomes crucial to understand how the prenatal co-use of these substances impacts birth outcomes. The goal of this study was to examine the risk of adverse birth outcomes among infants born to women who used tobacco and marijuana concurrently throughout pregnancy compared to infants of women who used tobacco alone.
Methods: This study involved a retrospective chart review of pregnant women identified via self-report or biochemical testing who used tobacco products alone (N = 71) or tobacco and marijuana simultaneously (N = 127) at any point throughout pregnancy.
Background: The goal of this study was to examine if in utero cannabis exposure predicted reduced birth size and if these effects were evident in specific growth parameters as early as the second trimester.
Methods: Eligible women had an initial prenatal visit between January 1, 2010, and March 31, 2020, completed an anatomy ultrasound between 18-24 weeks' gestation, and had no self-reported alcohol, tobacco, or other biochemically verified drug use. The two primary study groups were cannabis users (n = 109) identified through self-report and urine toxicology screens, and a randomly selected control group of non-substance users (n = 171).
