Study breakdown

Most Colorado women reported healthcare workers discussed cannabis during pregnancy

Longitudinal SurveyModerate evidence
The takeaway

Two-thirds of Colorado mothers reported a healthcare worker discussed cannabis during prenatal visits, but perinatal cannabis users were more likely to trust cannabis websites and stores than healthcare providers for information.

29% of users trusted cannabis websites over clinicians

What the researchers found

67.8% of women reported an HCW discussed cannabis at prenatal visits. Women who used cannabis perinatally were more likely to report HCW discussions (82.2% vs. 65.3%, p<0.01). However, perinatal users more often trusted cannabis websites (28.9% vs. 6.5%), stores (15.7% vs. 3.8%), and word-of-mouth (28.4% vs. 17.1%). HCW discussions were not associated with cannabis use during breastfeeding.

Why it matters

Even when healthcare workers discuss cannabis, perinatal users trust non-medical sources more. This suggests the content or approach of clinical conversations may not effectively reach women most at risk.

The numbers in context

3,193 Colorado mothers. 5.8% used cannabis during pregnancy or while breastfeeding. 67.8% reported HCW discussion. Cannabis users trusted: cannabis websites (28.9%), word-of-mouth (28.4%), stores (15.7%).

How the study worked

Health eMoms longitudinal survey of 3,193 Colorado mothers (2018-2020). Logistic regressions assessed HCW cannabis discussions and perinatal/breastfeeding cannabis use, adjusted for sociodemographic factors.

What this study cannot tell us

Colorado-specific results in a state with legal recreational cannabis. Self-reported data. Cannot assess quality or content of HCW discussions. Women who used cannabis may recall discussions differently.

How to read the evidence

State-representative longitudinal survey with adequate sample, but self-reported data and Colorado-specific context.

The bigger picture

The disconnect between having clinical conversations and influencing behavior suggests healthcare workers may need different communication strategies. Simply telling patients to avoid cannabis is insufficient when competing information from cannabis industry sources contradicts that advice.

Questions still open

  • What makes HCW cannabis conversations effective vs. ineffective? Would different messaging approaches reach perinatal cannabis users who currently trust commercial sources?

Common questions

Do doctors talk to pregnant women about cannabis?
In this Colorado survey, about two-thirds of mothers reported their healthcare worker discussed cannabis during prenatal visits. The rate was higher among women who used cannabis (82%).
Do these conversations change behavior?
Not clearly. HCW discussions were not associated with reduced cannabis use during breastfeeding, and perinatal cannabis users were more likely to trust cannabis websites and stores than their healthcare providers.
