Which department developed the drug recognition process techniques?

The development of drug recognition process techniques is primarily attributed to the Los Angeles Police Department (LAPD). In the 1970s, LAPD officers recognized the need for a structured method to evaluate drivers suspected of being impaired by drugs. This led to the establishment of the Drug Recognition Expert (DRE) program, which aimed to train law enforcement personnel in identifying the effects of various drugs on individuals and assessing their impairment.

Through extensive research and practical application, the LAPD contributed to shaping standardized procedures and assessment tools that are now used widely across law enforcement agencies, forming the basis for drug evaluation procedures that have been adopted by various jurisdictions. This program has become integral to traffic safety and law enforcement in addressing driving under the influence of substances.
