During 1994 to 2003 the number of patients treated in the Psychiatric Centre Bohnice who had within the first three dismissory diagnosis alcohol related disorders increased by 77% and disorders caused by other psychoactive drugs increased more than four times. An increase was observed also in pathological gambling (37%). In alcohol related problems the highest increase was seen in drug cessation (about four times). In other drug related problems the highest increase was marked in addiction treatment (almost five times). Such trend probably reflects the situation in the society together with other effects described in the study.
