Pregnant women using marijuana may be inadvertently jeopardizing their babies’ well-being, with a new study suggesting a direct link between cannabis exposure during pregnancy and adverse outcomes linking to low birth weight.
Quantifying the Risks: Unpacking the Data
In a recent report featured by NBC News, in December 12, 2023, analyzing data from over 9,000 expectant mothers across the U.S., the study, published in the Journal of the American Medical Association, reveals an alarming association between cannabis use and heightened risks, particularly concerning low birth weight. Dr. Torri Metz, the study’s lead author and an associate professor at the University of Utah Health, emphasizes that the risk intensifies with increased cannabis consumption during pregnancy,emphasizing the recommendation for pregnant women to abstain from marijuana use.
The research delves into a combination of potential negative outcomes, including low birth weight, medically induced preterm birth, stillbirth, and pregnancy-related high blood pressure. The overall risk surges by almost 30% among pregnant individuals who use cannabis, with a particularly noteworthy 50% increase in the risk of low birth weight.
As placental function is central to these low birth weight outcomes, previous research has shown that cannabis exposure adversely affects the placenta, the crucial source of nutrients and oxygen for the developing fetus. While other risks such as stillbirth and neonatal complications also show an increase, the statistical significance remains uncertain, emphasizing the intricate relationship between cannabis use during pregnancy and potential health complications for newborns.

Long-Term Implications and Health Concerns
According to the data released by WebMD, identified babies with low birth weight, defined as smaller than 95% of their counterparts, may face heightened health risks later in life, such as obesity. This study aligns with previous research in 2021 reporting health issues in children born to mothers who were heavy cannabis users during pregnancy. As an increasing number of states legalize marijuana for recreational use, these findings underscore the importance of understanding and mitigating the risks associated with marijuana use during pregnancy.
The study draws on data spanning from 2010 to 2013, providing a nuanced examination of the impact of marijuana use such as low birth weight for infants during different trimesters, urging healthcare providers and policymakers to consider the potential ramifications and promote informed choices for expectant mothers.
