Comorbidities in Drug Use Disorders: No wrong door

This discussion paper aims to highlight the evidence related to mental and physical health comorbidities in drug use disorders and to promote the development of innovative, evidence-based policies and practices to treat drug use disorders and comorbid disorders.

The paper advocates for an integrated approach to treatment from a biopsychosocial perspective and the ‘no wrong door’ principle, so that patients receive comprehensive therapeutic interventions regardless of their entry point in the health system.
