"The Australian Institute of Criminology has undertaken research into the offending and drug use careers of adult males, females and juveniles incarcerated in Australian prisons and detention centres. The objective of the Drug Use Careers of Offenders (DUCO) project is to further understand the drug use and criminal histories of incarcerated offenders and to contribute to the empirical evidence on the link between drug use and crime. This monograph, the third and final instalment in the DUCO project, examines the offending and drug use histories of 371 young offenders incarcerated in juvenile detention centres across Australia."
