What type of drugs can the NIK System presumptively identify?

The NIK System is designed to provide a rapid presumptive identification of most common drugs of abuse. This includes a variety of illicit substances such as cocaine, heroin, methamphetamine, and marijuana, among others. Law enforcement agencies frequently use this system in the field because it offers immediate results that can assist with the decision-making process during investigations or arrests involving suspected drug use.

The identification process using the NIK System relies on chemical reactions that produce noticeable changes, often involving color changes, which indicate the presence of specific drugs. This speed and efficiency are why it is particularly valuable in situations where timely information is critical.

The other options do not accurately reflect the capabilities of the NIK System. For instance, it is not limited to stimulants only, nor can it identify all medical prescriptions, as it primarily focuses on illegal substances. Additionally, while the NIK System can be used in the context of various substances, it is not designed to identify alcoholic beverages specifically, which typically require different testing methods.
