Background: Peer support work for substance use disorders is widely implemented in high-income countries. More research is still needed to understand its applicability in settings which have proportionately low budgets allocated to mental health. Peer Support Workers are individuals who managed to achieve recovery from substance use disorders and help people remain engaged in their recovery and prevent relapse through shared understanding.Aim: To investigate the experience of peer support workers providing recovery support to people with substance use disorders in Egypt.Methods: A qualitative phenomenological design was used in which 17 adults working as peer support workers for substance use disorders were recruited by means of purposive and snowball sampling. A semi-structured interview with participants was conducted by phone or video-call. Interviews were transcribed and thematically analysed based on descriptive phenomenology.Results: Three superordinate themes were identified: role responsibility, Peer Support Workers’ need for organizational and stakeholders’ support, and challenges to the role integrity.Conclusion and recommendations: The findings indicate the need for national and governmental support to peer support workers engaged with people with substance use disorders in Egypt and educating families and the public about the role of peer support workers in substance use disorders.
