title: Prevalence and risk factors for cannabis use in low-income pregnant women in São Paulo, Brazil.
abstract: Cannabis is the most commonly used illicit drug during the perinatal period and has potential risks to the fetus. The purpose of this study is to estimate the 1-year prevalence of cannabis use and identify associated factors for a population of low-income pregnant women in Brazil. We performed a cross-sectional analysis of 831 women surveyed using a structured questionnaire to collect sociodemographic, clinical, and substance use history. The 1-year prevalence of antenatal cannabis use was 4.2 %; reported lifetime use was 9.6 %. The presence of a common mental disorder and active tobacco smoking were independently associated with cannabis use, OR = 3.3 (95 % CI 1.65-6.59) and OR = 6.89 (95 % CI 3.45-13.8), respectively.
