Screening and brief intervention in illicit drug users.

Illicit drug use is quite prevalent in the Czech population with a lifetime prevalence of illicit drug use being 29.7 % in 2018. People who use illicit drugs can use health care services more often and they are thus relevant in early identification of illicit substance use disorders and in providing brief intervention. Primary evaluation of presence of illicit substance use disorders can be done using simple and fast screening questionnaires, such as DAST-10. Screening is followed with time effective brief intervention that includes education, advice and motivation for ceasing drug use. Brief intervention should always precede potential referral to specialised addiction services. Implementation of the evidence-based guidelines into daily practise can have a positive effect on early problem resolution, lead to reduction or termination of substance use and decrease harms on patients health and other areas of his life. Screening of illicit drug use, brief intervention in case of positive screening and eventual referral to a specialist should be implemented into routine medical care.
