In Europe, the prerequisites of equitable substance use treatment (SUT) for migrants and ethnic minorities (MEM) remain understudied. This qualitative study maps barriers and facilitators identified by 14 professionals in Flanders, Belgium. The analysis identified micro and meso level barriers and how they intersect. Whereas barriers to treatment are often attributed to the client (vulnerabilities, language, trust, knowledge) our results demonstrate that they are also rooted in services (lack of expertise, issues with interpreters, diversity policies, waiting list and referral bias). These results emphasize the responsibility of meso and macro policymaking in resolving treatment mismatch problems.
