As shown in Table 1, AA women were significantly more likely to report childhood maltreatment (27.3%) than were EAs (15.6%), although age at first maltreatment did not differ by race/ethnicity (M=8.0 [SD=4.0] years for EAs, 8.3 [SD=3.9] years for AAs). Cannabis use was more commonly reported by AAs (57.5% vs 52.5% among EAs), although the percentages of respondents who initiated before age 15 (9.0% vs 7.8%) and who initiated age 15 or later (48.5% vs 44.7%) did not differ by race/ethnicity nor did mean age at first use (AA M=17.1 [SD=2.7], EA M=16.8 [SD=2.5]). AA cannabis users were more likely than their EA counterparts to have experienced one or more cannabis problems (35.5% vs 24.5% of users respectively). Nearly all reported ages of onset of maltreatment preceded onset of cannabis initiation. Excluding 15 individuals with cannabis initiation prior to maltreatment (difference in onset age of 1–2 years for 14 individuals, 8 years for one person) did not alter findings.
