Most people with a history of psychotic experiences or diagnoses who used psychedelics reported personal growth, mystical-type experiences, improved insight, and feelings of love and appreciation. In an online retrospective survey of 100 such individuals, 88% said their psychedelic experience led to some degree of personal growth. However, 11% described overall negative experiences including symptom exacerbation, dysphoria, and terror, and a slightly larger portion reported mixed experiences. The findings suggest that while many individuals with psychotic histories may benefit from psychedelic experiences, a notable minority experience adverse effects, challenging assumptions that this group should be universally excluded from psychedelic research.

Ketamine-assisted therapy, when given to both partners during Imago Relationship Therapy, produces a wide range of effects including empathogenic, mystical, anxiolytic, and antidepressant experiences. Participants reported heightened awareness, vulnerability, and communication, along with lower defenses and novel somatic sensations. The drug's short duration, rapid onset, and cumulative effects were noted, alongside transient mild side-effects. Statistical tests indicated improved relationship satisfaction after treatment. The findings suggest ketamine may have therapeutic benefits in couples therapy under clinical supervision, but more research is needed.

Serotonergic psychedelics, which are being explored for treatment-resistant depression, might also help with depressive and negative symptoms in schizophrenia spectrum disorders (SSDs). Schizophrenia and depression share some underlying brain disturbances, including problems with dopamine, glutamate, and neuroplasticity, as well as abnormal brain network connectivity. Depressive symptoms in SSDs may combine features of both disorders, and psychedelics could potentially recalibrate maladaptive brain networks. Preclinical studies show psychedelics increase dendritic spines and BDNF and restore reward sensitivity. Clinical evidence is limited: uncontrolled psychedelic use is linked to increased psychosis, but controlled administration may be tolerated in stable individuals. Only one early-phase trial with MDMA in schizophrenia is ongoing; no randomized trials have tested psilocybin or LSD in SSDs. The authors conclude that psychedelics are biologically plausible but unproven for these symptoms.

People with histories of psychotic symptoms who used psychedelics in naturalistic settings reported both benefits and harms. Benefits included personal growth, insight, increased spirituality, and symptom reappraisal. Challenging experiences and adverse effects also occurred, especially when set and setting were unfavorable. The findings question the categorical exclusion of this population from psychedelic research and therapy, and call for more holistic, ethically guided study of psychedelic-assisted therapy for this underserved group.
