The links between substance use and offending are well evidenced in the literature, and increasingly, substance misuse recovery is being seen as a central component of the process of rehabilitation from offending, with substance use identified as a key criminogenic risk factor. In recent years, research has demonstrated the commonalities between recovery and rehabilitation, and the possible merits of providing interventions to substance-involved offenders that address both problematic sets of behaviours. This review paper therefore provides an overview of the links between substance use and offending, and the burgeoning literature around the parallel processes of recovery and rehabilitation. This is provided as a rationale for a new treatment approach for substance-involved offenders, Breaking Free Online (BFO), which has recently been provided as part of the Gateways throughcare pathfinder in a number of prisons in North-West England. The BFO programme contains specific behaviour change techniques (BCTs) that are generic enough to be applied to change a wide range of behaviours, and so is able to support substance-involved offenders to address their substance use and offending simultaneously. This dual and multi-target intervention approach has the potential to address multiple, associated areas of need simultaneously, streamlining services and providing more holistic support for individuals, such as substance-involved offenders, who may have multiple and complex needs. Recommendations are provided to other intervention developers who may wish to further contribute to widening access to such dual-focus programmes for substance-involved offenders, based on the experiences developing and evidencing the BFO programme.
