Abstinence and drug abuse treatment: Results from the Drug Outcome Research in Scotland study.

Aims: To identify the proportion of drug users contacting drug treatment services in Scotland who were able to become abstinent 33 months after having started a new episode of treatment and to identify which services were most closely associated with such abstinence. Design: Follow-up survey of 695 of the Drug Outcome Research in Scotland respondents 33 months following recruitment into the study. Setting: Scotland. Participants: Injecting drug users who were initially contacted at drug treatment services and then followed up for 33 months post-recruitment. Measurements: Self-reported drug use and service usage. Findings: Although becoming drug free was the expressed goal of the majority of drug users recruited into the Drug Outcome Research in Scotland study, at 33 months following recruitment only 5.9% of females and 9.0% of males had been totally drug free (excluding possible alcohol and tobacco use) for a 90-day period in advance of being interviewed. There was considerable variation within this study in the proportion of drug users becoming drug free dependent upon the services they had been in contact with. The level of achieved abstinence in this Scottish study was substantially lower than that identified in the National Treatment Outcomes Research Study in England. Conclusions: There is a need to establish why so few drug users in contact with the methadone programme in Scotland appear able to become drug free 33 months after having contacted this service. On the basis of the results presented in this paper there is a need to ensure that drug users seeking help in becoming drug free are able to access residential rehabilitation services although at the present time such services are relatively rare within Scotland.
