What does the NIK System of narcotics identification primarily allow officers to do?

The NIK System of narcotics identification is specifically designed to assist law enforcement officers in quickly screening and presumptively identifying illicit drugs at the scene. This rapid identification is crucial for officers to make informed decisions regarding enforcement actions, such as whether to detain an individual for further investigation or to collect evidence. The system typically includes a range of chemical test kits that can provide immediate results, helping officers to ascertain the presence of specific substances without the need for extensive laboratory analysis at that moment.

This quick identification capability is vital in scenarios where time is of the essence, such as preventing further distribution of drugs or ensuring the safety of individuals involved. While other options, such as arresting individuals or conducting long-term investigations, are part of broader law enforcement practices, they do not directly relate to the specific function of the NIK System. The system is not designed to conduct psychological evaluations, which is why that option does not fit within the context of the question.
