Psychedelic therapy - refining the claim of a paradigm shift.

The renewed interest in psychedelics as treatments for mental health disorders is often referred to as the "Psychedelic Renaissance." This article assesses whether this resurgence truly constitutes a paradigm shift in psychiatry, as some proponents claim, or if it should be viewed as an integration of existing therapeutic approaches. We explore historical contexts, noting that psychedelics were extensively researched in the mid-20th century and argue that many of the current claims about their novelty overlook prior knowledge and research from that period. While psychedelics do introduce novel aspects, such as rapid therapeutic effects and unique modes of action, we challenge the idea of a full paradigm shift, suggesting that these developments are better understood as enhancements to existing frameworks rather than a wholesale replacement. We emphasize the importance of integrating psychedelics within a broader bio-psycho-social model of psychiatry, combining pharmacological, psychological, and contextual factors. The therapeutic potential of psychedelics in psychotherapy has previously been described as working as "nonspecific amplifiers" of psychological processes, rather than introducing entirely new mechanisms. We suggest a balanced, integrative approach that incorporates psychedelics into existing mental health care models, cautioning against "psychedelic exceptionalism" and the risk of overselling their potential as a revolutionary treatment.
