Abstract

Data were analysed from 62 schizophrenic patients between 18 and 30 years of age, treated at the community mental health centres in Navarra, who had relapsed and then completed a one-year follow-up study. Factors influencing the course of illness during follow-up were: continuing cannabis consumption; previous cannabis intake; non-compliance with treatment; and stress.
