What This Study Found

Five themes emerged: pregnancy as a turning point for cannabis use, cannabis for emotional regulation, complex cannabis-mental health ties, relational influences on use, and contextual barriers to informed decision-making — with emotional regulation and mental health as the most cited drivers.

Key Numbers

19 pregnant cannabis users interviewed; most Medicaid recipients; nearly half reported household income below $10,000; study conducted in Wisconsin where cannabis is illegal.

How They Did This

Reflexive thematic analysis of qualitative interviews with 19 pregnant cannabis users from a community-based program in Wisconsin (where cannabis remains illegal), most on Medicaid with nearly half below $10,000 household income.

Why This Research Matters

Understanding why pregnant women use cannabis — not just that they do — is essential for designing supportive rather than punitive public health interventions.

The Bigger Picture

These findings challenge the narrative that prenatal cannabis use is simply reckless behavior — for many low-income women, it's a coping mechanism for untreated mental health conditions in a system with inadequate support.

What This Study Doesn't Tell Us

Small qualitative sample from a single state where cannabis is illegal; findings may differ in legal states; self-selected participants in a community program.

Questions This Raises

  • ?Would providing accessible mental health services reduce prenatal cannabis use?
  • ?How does cannabis legalization status affect pregnant women's willingness to discuss use with providers?
