A criminal investigator looks for clues and evidence to determine whether a crime a crime has taken place. An investigator must learn the general modus operandi of these individuals, including the slang terms used in the drug culture. Total knowledge of and the use of appropriate slang terms are must in the development of rapport with contacts (overt or undercover) and can lead to fruitful sources of information.

At times, it will be necessary to utilize information just to achieve the first determination that "a narcotics or dangerous drugs abuse exists."
