There is increasing recognition that recovery from heroin addiction is possible but there is limited understanding of the recovery process and of how services can support people in that process. At present, most of the research concerning recovery from heroin addiction comes from the United States where the treatment system is very different to that in the UK. This study aimed to gain a better understanding of the recovery process from the perspective of people who are in recovery from heroin addiction, with the aim of informing service development and delivery in the South Wales area. This study employed a grounded theory qualitative methodology to analyse data collected from ten interviews with people in recovery from heroin addiction in the South Wales area. The results revealed four core categories: i) initiating recovery, including the triggers for recovery and what helps; ii) maintaining recovery, consisting of thought changes, lifestyle changes and the role of supportive networks; iii) the reality of recovery, encompassing the process of recovery and obstacles faced; and iv) service provision, encompassing current problems, how support needs can be met and how wider needs can be addressed. The findings highlighted some important considerations for the development of services specifically designed to meet the needs of this client group, thus facilitating long term stable recovery. The findings are reviewed in relation to the wider literature regarding recovery from heroin addiction. Implications for clinical practice and service delivery are also reviewed, and suggestions provided for how services can incorporate recovery-orientated principles. Suggestions for future research are also considered.
