Abstract
The article presents the case of a 16-year-old patient who developed psychosis following prolonged use of tetrahydrocannabinol. The clinical picture is described in detail, including disturbances in perception, cognition, and affect, complemented by information obtained through interviews with the patient and his parents during inpatient psychiatric treatment. The course of cognitive behavioural therapy is outlined, with particular emphasis on the stepwise formulation and implementation of therapeutic goals in collaboration with the patient. Attention is drawn to the relevance of current evidence-based guidelines, highlighting the role of psychoeducation, relapse prevention strategies, and motivational work to support abstinence. This case illustrates the importance of early intervention, individualised treatment planning, and family involvement in the therapeutic process of substance-induced psychosis.
