In general, users of screening tests should be cautious in addressing the identified individuals as problem cannabis users without considering the particular problems the test is referring to. On the other hand, depending on the purpose a screen is used for (e.g., prevalence estimation, clinical assessment) the recipients of the results should be made aware of the psychometric properties of the test. The choice of the cut-off determines the proportion of targeted but not identified individuals as well as the proportion of individuals who although identified do not fulfil the reference criteria.
