  • The shadow side of motives

    Open AccessStéphane Potvin, Yasser KhazaalARTICLEFrontiers in Psychiatry2026

    Substance use disorders (SUDs) can be seen as incomprehensible or perhaps shocking to some people, as those affected with SUDs may persist in their consumption even though it is clearly associated with harmful consequences that are readily apparent to them and/or to those around them.
