Mandatory Warning Signs for Cannabis: Perspectives and Preferences of Pregnant and Recently Pregnant People Who Use Cannabis.

OBJECTIVE

Five U.S. states where recreational cannabis is legal require mandatory warning signs for cannabis use during pregnancy (MWS-cannabis) to be posted in cannabis dispensaries. Previous research has found adverse health consequences associated with MWS-cannabis and that people lack trust in information on signs. This qualitative study explores people's perspectives and preferences regarding MWS-cannabis.

METHOD: We conducted in-depth interviews with 34 pregnant or recently pregnant individuals from multiple states with varying policy climates in the United States who used cannabis before or during pregnancy. We asked participants about their perspectives on MWS-cannabis and reactions to specific messages. We reviewed transcripts using thematic analysis.

RESULTS

Participants reported mostly negative views on MWS-cannabis, suggesting that they may have stigmatizing and negative impacts on pregnant people who use cannabis, discouraging them from seeking care. Many said that the scientific evidence is not strong enough to justify MWS-cannabis and that they are unlikely to deter pregnant people from using cannabis. Participants asserted that vague or fear-based messages, distrust of government, and the location and timing of the signs undermine the goals of MWS-cannabis. When reacting to specific messages, participants preferred messages that are evidence-based, clear, specific, and aligned with autonomous decision-making.

CONCLUSIONS

Pregnant and recently pregnant people who use cannabis have mostly negative perceptions of MWS-cannabis and believe they have negative consequences. More work is needed to develop health information resources that meet the needs of people who use cannabis during pregnancy without increasing stigma.
