According to the research, it was found that addictive substances were used by more than half of the respondents during VTOS. These were mostly meth, THC, alcohol and benzodiazepines. 18% of respondents mentioned the method of injecting addictive substances in prison and 9% of respondents stated the sharing of application aids. According to the majority of respondents, sexual intercourse takes place in prison and the possibility of protection against sexually transmitted diseases is low. Of the 81% of respondents who were tested for infectious diseases during VTOS, 48% of respondents suffered from an infectious disease, most often hepatitis C. The possibilities of preventing infectious diseases in the prison environment appear to be insufficient. There is interest in substitution treatment, but it is little offered [22].

Prisoners should be psychosocially stabilized at the end of their sentences and their treatment should continue after release.
