Education policies encourage inclusion of students with mild-intellectual disability (mild-ID) in community/school life. However, such policies potentially increase exposure to substance use. This article examines tobacco, alcohol and cannabis use among French students enrolled in special units for students with disabilities (ULIS) at mainstream junior high schools compared to those of general population of the equivalent age; and explores factors associated with substance use among ULIS students, known to present mostly mild-ID. In 2014, a questionnaire adapted from the international HBSC/WHO study was administered to 700 ULIS students (mean-age 14.2). Comparative data were gathered from 7023 junior high-school students (mean-age 13.6) in the general population. Among students <14 years-old, tobacco and alcohol use rates were similar between ULIS and general population. For students ≥14, alcohol use remained comparable, while tobacco and cannabis use were higher in general population. Among ULIS students, low perceived health/life satisfaction, divorced/separated parents and high perceived academic demands were associated with tobacco use. Bullying, not liking school very much and attending schools outside a deprived area were associated with alcohol use. Having had sexual intercourse and not perceiving one's health as excellent were associated with cannabis use. Having dated was associated with using all three substances.
