title: Interim methadone treatment: impact on arrests.
abstract: OBJECTIVE
  This study examines the frequency and severity of arrest charges among heroin addicts randomly assigned to either interim methadone (IM) maintenance or to remain on a waiting list for methadone treatment. It was hypothesized that IM participants would have a: (1) lower number of arrests at 6 and 12 months and (2) lower mean crime severity scores at 6 and 12 months post-baseline.
  
  
  METHODS
  Available official arrest data were obtained for all 319 study participants for a period of 2 years before and after study enrollment. Crime severity ratings of charges were made using an established measure of crime severity.
  
  
  RESULTS
  Participants randomly assigned to IM as compared to those on a waiting list had a significant reduction in number of arrests at 6 but not at 12 months from study enrollment. There were no significant differences in whether participants were arrested for a more severe crime but frequency of severe crime was relatively low in both groups. Additional post hoc analyses based on whether participants were in methadone treatment at 4 and 10 months after original random assignment to treatment condition revealed that those participants not in treatment at these follow-up assessment points were significantly more likely to be arrested and to have a higher mean crime severity rating at 12 and 24 months post-baseline assessment.
  
  
  CONCLUSIONS
  IM as compared to the waiting list condition, had a significant reduction in number of officially recorded arrests from baseline to 6 months post-baseline. Those who were enrolled in methadone treatment at the 4- and 10-month follow-up assessment, regardless of initial assignment, had fewer arrests at 12 and 24 months post-baseline.
