As the legalization of cannabis becomes more prevalent across the United States, its use has surged, particularly among pregnant individuals seeking relief from common pregnancy-related symptoms such as nausea and anxiety.
However, recent research from the University of Utah Health has raised concerns about the safety of cannabis during pregnancy, indicating that its use could lead to a higher likelihood of negative health outcomes.
The study, which examined over 9,000 pregnant individuals across eight medical centers, revealed that cannabis use during pregnancy is associated with a 1.3 times increased risk of complications, including low birth weight, medically induced preterm birth, stillbirth, and pregnancy-related blood pressure disorders.
The psychoactive component of cannabis, THC, is capable of crossing the placenta and potentially impacting fetal development.
Dr. Torri Metz, the lead researcher and an OB/GYN at University of Utah Health, emphasized that neurodevelopment is an ongoing process throughout pregnancy, affecting the fetus well into the third trimester.
“There are problems with attention later in life for babies exposed to cannabis in utero,” Metz noted, highlighting the potential long-term impact of prenatal cannabis exposure.
While pregnant individuals may believe that cannabis is a natural remedy, Metz urged that many studied alternatives exist, which are deemed safer for managing pregnancy symptoms without jeopardizing fetal health.
For fever or body aches during pregnancy, acetaminophen is considered safe.
In cases of nausea, medical professionals may recommend medications such as Zofran or Diclegis that have been researched and verified as safer for pregnant patients.
For those experiencing anxiety or stress, several methods can provide relief without the risks associated with cannabis.
Simple physical activities like taking short walks or performing stretching exercises have demonstrated effectiveness in reducing stress.
Mindfulness practices, such as meditation and yoga, are also considered safe and beneficial for managing anxiety during pregnancy.
Seeking therapy from licensed mental health professionals can offer pregnant individuals coping strategies tailored to their specific needs and circumstances.
If traditional methods prove ineffective, doctors may prescribe SSRIs like Prozac, Zoloft, or Celexa, which are acknowledged as safe during pregnancy.
The perception that cannabis’s natural origin equates to safety is a misconception that Metz seeks to correct.
“It’s essential for patients to have open conversations with their healthcare providers about their cannabis use and explore safer, vetted alternatives for dealing with nausea, anxiety, and depression,” Metz advised.
For those who have regularly used cannabis and discover they are pregnant, early cessation is highly recommended.
“Stopping as soon as possible will help minimize the impact on the placenta and fetal neurodevelopment,” Metz stated, reinforcing the importance of acting swiftly.
Individuals concerned about their cannabis use or experiencing substance use disorders have access to numerous resources to support a healthy pregnancy.
One such resource is the Substance Use and Pregnancy-Recovery, Addiction, and Dependence (SUPeRAD) Clinic at University of Utah Health.
This clinic offers individualized, non-judgmental care for pregnant and postpartum individuals dealing with substance use disorders, and it stands out as the first of its kind in the Mountain West.
Since its establishment in 2017, the SUPeRAD Clinic has successfully treated over 1,300 pregnant patients.
As the findings surrounding cannabis use during pregnancy continue to evolve, healthcare providers are encouraged to inform and assist pregnant individuals in making well-informed decisions that prioritize both their wellbeing and that of their unborn child.
