Substance-induced psychoses (SIPs) triggered by novel psychoactive substances differ from endogenous psychoses like schizophrenia in three key ways: dissociation, mental automatism, and temporality. Dissociation in SIPs causes fragmentation of consciousness and identity detachment, distinct from the spaltung seen in schizophrenia. Mental automatism, as described by De Clerambault, appears early in SIPs with cognitive disruptions preceding delusions. Temporally, SIPs trap individuals in an eternal present, disconnected from past and future, unlike the fragmented temporality in schizophrenia. The paper argues that a phenomenological approach aids clinical differentiation and targeted interventions.
