Methods: In the analysis, registry of sick leaves were analysed. Provided analysis is focused on the length of sick leaves related to mental diseases caused by substance use or other factors. Dependent variable is the sick leaves length, and the independent variables are categories of disease and occupation. Kruskal–Wallis test, Shapiro–Wilk test, Brown–Forsythe (B–F) are used. Results: There are differences in mental sick leave lengths caused by substance use or other factors. In the case of mental illnesses attributable to drugs, differences in the sick leave duration among different working groups were not found. Considering mental disorders caused by other factors, there are differences in the sick leave duration among different working groups. Conclusions: There is no evidence of longer sick leave in people diagnosed with mental disorder related to substance use. Differences in occupational categories do not relate to sick leave length.
