More than 3,500 offenders being supervised by probation services in Northern Ireland have problems with drug and alcohol misuse.
The number equates to more than 70% of all 5,000 criminals who are on probation in the region.
The scale of the drink and drug problem among offenders was outlined by the Probation Board for Northern Ireland (PBNI).
It has outlined the figures to highlight the extent to which alcohol and substance abuse contributes to criminal and anti-social behaviour.
The acting director of PBNI Cheryl Lamont said the percentage of those experiencing misuse problems was concerning.
"Given that we supervise almost 5,000 offenders, this is a significant number of people presenting with alcohol or drug problems," she said.
