This is a cross-sectional study of 226 cases of patients with schizophrenia in hospital in the psychiatric Department of CHU Mohammed VI in Marrakech between January 1, 2017 and October 31, 2018.The mean age is 27.02 ( 9.4) years, with a male predominance of 67.2 %, paranoidschizophreniawas the most common form 46.9 %. SPA use was present in 63.7 % of cases ; cannabis was the most consumed substance (54.8 %), followed by alcohol (21.2 %), then benzodiazepines (15.9 %). The use of spas preceded schizophreniain 49.5 % of cases. Users of psychoactive substances are characterized by male predominance 46 %, early on set of schizophrenia, and acute entry mode.
