The study aims to provide insight into the lives of parents to adult children with drug addiction. We focus on how the parents' social life and interactions were affected by feelings of guilt and shame, and how they dealt with the stigma that often accompanies drug addiction. 32 semi-structured interviews were conducted with parents (age 46-70) of adult children (age 18-47) with drug addiction in Sweden. Three themes emerged (1) Experiences of guilt, shame, and courtesy stigma, (2) Impact on social life and relationships and, (3) Strategies to reduce guilt and shame. Guilt, shame, and courtesy stigma complicated and restricted the parents' social interactions. Many parents applied a selective openness, carried experiences of alienation and in some cases isolated themselves. At the same time, several parents described that they were open about their child's addiction in certain contexts. For some parents, this meant a relief from guilt and shame and an opportunity for increased social interaction. Both informal and professional support for family members of individuals with drug addiction is vital to reduce experiences of guilt, shame, and courtesy stigma.
