AIMS This study investigates changes in criminal involvement among patients in opioid maintenance treatment (OMT) over a 7-year period prior to, during and after treatment, particularly in relation to differences in treatment engagement. DESIGN, SETTING AND PARTICIPANTS Treatment data on all patients who started OMT in Norway between 1997 and 2003 (n = 3221) were cross-linked with national criminal records. The period of observation was divided into four phases; pre-treatment, in-treatment, between treatments and post-treatment. FINDINGS During OMT, rates of criminal convictions for the cohort were reduced to fewer than half of waiting-list levels [incidence rate (IR) 0.63 versus 1.57]. Patients in continuous treatment had the fewest convictions (IR 0.47) during treatment. The highest rates were found among patients out of treatment after several treatment episodes (IR 1.52). All groups had significantly fewer criminal convictions during treatment compared to before treatment. Staying in OMT for 2 years or more was associated with significantly reduced rates of convictions during treatment. Younger age and pre-treatment criminal convictions were associated with significantly (P < 0.001) more convictions during treatment. Those who left treatment, permanently or temporarily, relapsed into high levels of convictions outside treatment. CONCLUSIONS Criminal activity appears to be reduced in Norway during opiate maintenance treatment. Younger age and prior history of criminal activity are important risk factors for continued criminal activity during treatment.

INTRODUCTION The use of methadone in opioid maintenance treatment (OMT) is potentially associated with a number of adverse effects and the risk of fatal toxicity. Increased methadone availability may lead to an increase in methadone-related deaths. We have investigated methadone-related deaths in Norway over the period 2000-2006. MATERIALS AND METHODS Methadone-positive samples over the period 2000-2006 were identified from forensic toxicological investigations, and demographic and toxicological data were retrieved. The cases were cross-linked with the Norwegian Cause of Death Registry and regional OMT registers. RESULTS A total of 312 individuals had died after taking methadone over the period 2000-2006, predominantly men with a mean age of 36. In 85% of cases (n=264), the deceased had died of a methadone-related intoxication, most often in combination with other drugs, including benzodiazepines, cannabis and other opioids. Only 22% of the deceased had been in OMT at the time of death. A larger proportion of OMT patients had died of causes other than intoxications compared to those not in OMT (30% vs. 8%, respectively), most commonly related to disease. CONCLUSIONS One methadone-related death occurred, on average, every week over the time period investigated. Only 22% of the deceased were registered in opioid maintenance treatment (OMT) programs. The findings underline the need to control diversion of medication from OMT programs.

This study investigates frequency and types of criminal convictions among a national sample of heroin users during a 3-year period prior to opioid maintenance treatment (OMT). All heroin users (N = 3,789) in Norway who applied for and were eligible for OMT (1997-2003) were included. The OMT records were cross-linked to Norwegian crime statistics. During observation, 24,478 convictions were recorded among 60.9% of the sample. Differences of criminal convictions were found within the group; a large proportion (39.1%) had no convictions, whereas 10% of the sample was responsible for 37.8% of all convictions. Convictions for acquisitive crimes and drug crimes were the most common. Variations in the cohorts individual crime sequences were found. The heavy involvement of heroin users with the criminal justice system provides an opportunity to intervene with dependent offenders. Coordination between treatment providers and police or courts can play an important role in improving outcomes through better access to treatment.

Reductions in convictions for violent crime during opioid maintenance treatment: A longitudinal national cohort study

BACKGROUND Although opioid maintenance treatment (OMT) has been found to reduce crime, less is known about its associations with violent crime. This study investigates changes in violent crime convictions prior to, during, and after OMT, and examines the relationship between violent crime convictions prior to OMT with the risk of violent and non-violent crime convictions during treatment. METHODS The cohort comprised all who started OMT (n=3221) in Norway between 1997 and 2003. Treatment data were cross linked with the national Crime Registry. Convictions for violent crime 3 years prior to, during, and after treatment were studied. RESULTS Violent crime rates were significantly reduced during OMT compared with before treatment, for both men and women. The rate of convictions for violent crime during OMT was halved amongst those who remained in treatment. The reduction was less pronounced for those who left treatment: for this group, the rate of violent convictions after OMT was higher than before treatment. The risk of convictions for violent and non-violent crime during OMT was highest for those with violent convictions prior to treatment. CONCLUSIONS Violent crime is reduced during OMT. Screening for violent behaviour and violence risk assessment should be implemented in the treatment system.

The role of substance use and morality in violent crime - a qualitative study among imprisoned individuals in opioid maintenance treatment

BackgroundOpioid maintenance treatment (OMT) is regarded as a crime control measure. Yet, some individuals are charged with violent criminal offenses while enrolled in OMT. This article aims to generate nuanced knowledge about violent crime among a group of imprisoned, OMT-enrolled individuals by exploring their understandings of the role of substances in violent crime prior to and during OMT, moral values related to violent crime, and post-crime processing of their moral transgressions.MethodsTwenty-eight semi-structured interviews were undertaken among 12 OMT-enrolled prisoners. The interviews were audio recorded and transcribed verbatim. An exploratory, thematic analysis was carried out with a reflexive and interactive approach.FindingsPrior to OMT, substances and, in particular, high-dose benzodiazepines were deliberately used to induce ‘antisocial selves’ capable of transgressing individual moral codes and performing non-violent and violent criminal acts, mainly to support costly heroin use. During OMT, impulsive and uncontrolled substance use just prior to the violent acts that the participants were imprisoned for was reported. Yet, to conduct a (violent) criminal act does not necessarily imply that one is without moral principles. The study participants maintain moral standards, engage in complex moral negotiations, and struggle to reconcile their moral transgressions. Benzodiazepines were also used to reduce memories of and alleviate the guilt associated with having committed violent crimes.ConclusionsSubstances are used to transgress moral codes prior to committing and to neutralize the shame and guilt experienced after having committed violent crimes. Being simultaneously enrolled in OMT and imprisoned for a (violent) crime might evoke feelings of ‘double’ shame and guilt for both the criminal behavior prior to treatment and the actual case(s) one is imprisoned for while in OMT. Treatment providers should identify individuals with histories of violent behavior and, together with them, explore concrete episodes of violence and their emotional reactions. Particular attention should be given to potential relationships between substance use and violence and treatment approaches tailored accordingly. What appears as severe antisocial personality disorder may be partly explained by substance use.
