Pregnant and Non-Pregnant Women Are Equally Uncertain About Cannabis Risks in Pregnancy

Cross SectionalPreliminary evidence
The takeaway

About 40% of pregnant participants chose "not sure" when asked about the risks of weekly cannabis use during pregnancy, and CBD uncertainty was even higher.

What the researchers found

Among 261 women surveyed, there was no significant difference between pregnant and non-pregnant participants in how they perceived the risks of cannabis or CBD use during pregnancy. The most common response for both groups was "not sure." Focus groups revealed that participants saw cannabis as fundamentally different from alcohol or other drugs and felt legalization signaled safety.

Why it matters

High uncertainty about cannabis and CBD risks during pregnancy, even among currently pregnant women, suggests a major gap in patient education. The finding that legalization itself shapes safety perceptions adds a policy dimension to the communication challenge.

The numbers in context

261 survey respondents (75.9% currently pregnant); 40% of pregnant participants said "not sure" about weekly cannabis risk; 52.3% of pregnant participants said "not sure" about weekly CBD risk; ever-use: 36% of pregnant vs 65.5% of non-pregnant for cannabis

How the study worked

Multi-method study combining a cross-sectional survey (261 respondents from outpatient obstetrics clinics) with five focus group discussions (17 participants total), conducted October 2022 to February 2023. Chi-square analysis compared risk perceptions between pregnant and non-pregnant participants.

What this study cannot tell us

Convenience sample from a single geographic area. Self-report data subject to social desirability bias. Small focus group sample. Cross-sectional design limits causal inference.

How to read the evidence

Preliminary: convenience sample from limited clinics, cross-sectional design, and small qualitative component.

When this study was published

2025 study with data collected 2022-2023

The bigger picture

As cannabis legalization expands, the gap between medical guidance (which advises against use in pregnancy) and public perception (which increasingly views cannabis as benign) may widen. This study highlights the disconnect.

Questions still open

  • What messaging strategies most effectively communicate uncertainty about cannabis safety in pregnancy?
  • Does CBD-specific uncertainty lead to higher CBD use rates during pregnancy?
