ABSTRACT

OBJECTIVES: Peripartum cannabis use can be harmful to pregnant individual’s and children’s health, yet it is the most used illicit substance during the peripartum period. Despite the ability of some people to reduce and abstain from cannabis use during pregnancy, the first year postpartum is a high-risk time for returning to cannabis. However, characterization of cannabis use patterns in the peripartum period and risk factors for return to use postpartum are not well established. The aims of this exploratory study were to describe patterns of peripartum cannabis use and identify factors associated with increased frequency of postpartum cannabis use among individuals who reported reduced use during pregnancy.

METHODS: An online survey identified 47 individuals who used cannabis during the peripartum period. Descriptive statistics characterized the sample and among those who reduced use during pregnancy, χ2 determined the frequency of postpartum cannabis use per preconception reasons for use.

RESULTS: During preconception, 95.7% of individuals used cannabis, and of those who were presently postpartum, 65% resumed use after delivery. Anxiety and stress were the most common motivations for cannabis use throughout the peripartum period, but social motivations (ie, fun, relaxation) were the only preconception factors that increased frequency of return to cannabis use postpartum.

CONCLUSIONS: Our exploratory study describes the characteristics of individuals using cannabis in the peripartum period and provides insight into correlates of resumption of cannabis use postpartum. These findings may inform future work to further determine temporal associations, confounding risk factors, and intervention techniques to prevent the return to cannabis use postpartum.
