Review warns of growing prenatal cannabis use despite mounting evidence of risks

Narrative ReviewModerate evidence
The takeaway

More pregnant individuals are using cannabis in the context of changing policy, despite recent studies showing perinatal and neurodevelopmental risks, and healthcare providers often fail to discuss the topic with patients.

Obstetricians, pregnant individuals, medical education programs

HCPs reluctant to discuss cannabis in pregnancy

What the researchers found

Recent studies show possible perinatal and longitudinal neurodevelopment risks from prenatal cannabis exposure. Healthcare providers are reluctant to discuss cannabis with pregnant patients for various reasons. Increased access through legalization may increase adverse effects.

Why it matters

The gap between increasing prenatal cannabis use and incomplete clinician communication about risks means many pregnant individuals are making decisions without adequate information about potential consequences.

The numbers in context

Cannabis use during pregnancy is increasing in the context of liberalized policy. Healthcare providers cite multiple reasons for reluctance to discuss cannabis with pregnant patients.

How the study worked

Narrative review of recent evidence on prenatal cannabis effects, covering perinatal outcomes, neurodevelopmental risks, and healthcare provider communication barriers.

What this study cannot tell us

Brief narrative review without systematic methodology. Does not quantify specific risk magnitudes. Healthcare provider perspectives not directly measured.

How to read the evidence

Brief narrative review provides an overview of current concerns but without systematic evidence synthesis.

2024 review of recent prenatal cannabis evidence

The bigger picture

The review highlights a systemic failure: even as evidence of prenatal cannabis risks accumulates, the medical system has not adequately translated this evidence into routine clinical conversations, leaving pregnant individuals to rely on non-medical information sources.

Questions still open

  • What specific barriers prevent clinicians from discussing cannabis with pregnant patients? Would standardized screening and counseling protocols improve prenatal cannabis conversations?

Common questions

Why are more pregnant people using cannabis?
Changing cannabis laws, increased availability, growing social acceptance, and some women using it to manage pregnancy symptoms like nausea, despite evidence of potential risks.
Why don't doctors discuss cannabis with pregnant patients?
Healthcare providers cite various barriers including discomfort with the topic, uncertainty about the evidence, concern about stigmatizing patients, and limited training on cannabis counseling.
