  • Background: Cannabis use during the perinatal period is rising. Objectives: To synthesize existing knowledge on the perspectives of pregnant people and their partners about cannabis use in pregnancy and lactation. Search strategy: We searched MEDLINE, APA PsycINFO, Cumulative Index to Nursing and Allied Health Literature, Social Science Citation Index, Social Work Abstracts, ProQuest Sociology Collection up until April 1, 2020. Selection criteria: Eligible studies were those of any methodology which included the perspectives and experiences of pregnant or lactating people and their partners on cannabis use during pregnancy or lactation, with no time or geographical limit. Data collection and analysis: We employed a convergent integrative approach to the analysis of findings from all studies, using Sandelowski’s technique of “qualitizing statements” to extract and summarize relevant findings from inductive analysis. Main results: We identified 23 studies of pregnant people’s views about cannabis use in pregnancy. Comparative analysis revealed that whether cannabis was studied alone or grouped with other substances resulted in significant diversity in descriptions of participant decision-making priorities and perceptions of risks and benefits. Studies combining cannabis with other substance seldom addressed perceived benefits or reasons for using cannabis. Conclusions: The way cannabis is grouped with other substances influences the design and results of research. A comparative analysis emphasizes the importance of understanding why a pregnant person might choose to use cannabis in order to foster dialogue about perceptions of benefit and strategies for risk mitigation.
