Substance Use Patterns of Indigenous and Non-Indigenous Women Offenders
Research Highlights: A greater proportion of Indigenous women offenders report problematic substance use in the twelve months prior to arrest.
Research in Brief- PDF
Why we did this study
Substance use issues continue to be prevalent among women offenders, particularly Indigenous women.Footnote 1Footnote 2 Given that Indigenous women are disproportionately represented among federally sentenced women, this study was conducted to examine differences in substance use patterns among Indigenous and non-Indigenous women.
What we did
The Women’s Computerized Assessment of Substance Abuse (W-CASA) assesses federal women offenders upon admission to custody.Footnote 3 In total, 908 women (35% Indigenous, n = 316) Footnote 4 completed the W-CASA between November 2016 and January 2019.
What we found
Eighty percent of federal women offenders reported problematic substance use in the twelve months prior arrest; 97% of Indigenous women compared to 71% of non-Indigenous women. Eighty percent of Indigenous women compared to 49% of non-Indigenous women had a moderate to severe substance use issue.
The majority of Indigenous women (92%) indicated using alcohol and/or drugs in the twelve-month period prior to arrest, compared to 75% of non-Indigenous women. Among women who used substances in the twelve months prior arrest, Indigenous women were more likely than non-Indigenous women to report CNS stimulantsFootnote 5 as the drug used most (27% versus 13%) while non-Indigenous women were comparable to Indigenous women for alcohol (20% versus 21%, respectively) and opioids (16% each).
Indigenous women were nearly twice as likely as non-Indigenous women to indicate a history of injection drug use (IDU; 46% versus 24%). Among those who reported IDU, sharing needles was reported by similar proportions (40% each). Two-thirds (67%) of Indigenous women compared to 42% of non-Indigenous women reported same day use of multiple drugs and/or alcohol.
Almost one-third (30%) of Indigenous women and 15% of non-Indigenous women indicated substance use while pregnant. both Indigenous and non-Indigenous women reported using alcohol most often while pregnant.
Criminal behaviour was linked to substance useFootnote 6 for over half (58%) of all women. Over three-quarters (78%) of Indigenous women compared to about half (48%) of non-Indigenous women reported this link. However, among those with a substantial to severe substance use issue, there was no difference between Indigenous and non-Indigenous women in the substance use-crime link (89% versus 87%, respectively).
What it means
Understanding substance use patterns, particularly in the twelve months prior to arrest, allows the Correctional Service of Canada (CSC) to provide targeted interventions, informed case management, and health services for Indigenous and non-Indigenous women. CSC’s correctional programs, including the Women Offender, Aboriginal Women, and Women Sex Offender Correctional Programs, address a multitude of criminogenic behaviours, including substance use. However, incorporating new information related to substance use patterns into interventions and case management as they emerge, such as the increased use of CNS stimulants among Indigenous women, further supports successful rehabilitation and reintegration.
