The International Drug Evaluation & Classification Program
The Drug Evaluation and Classification Program is recognized by all fifty states in the U.S., Canada, Hong Kong, and the United Kingdom.
About the DECP
The Los Angeles Police Department (LAPD) originated the program in the early 1970s when LAPD officers noticed that many of the individuals arrested for driving under the influence (DUI) had very low or zero alcohol concentrations. The officers reasonably suspected that the arrestees were under the influence of drugs, but lacked the knowledge and skills to support their suspicions. In response, two LAPD sergeants collaborated with various medical doctors, research psychologists and other medical professionals to develop a simple, standardized procedure for recognizing drug influence and impairment. Their efforts culminated in the development of a multi-step protocol and the first drug recognition expert (DRE) program. The LAPD formally recognized the Drug Recognition Expert program in 1979. It was later renamed the Drug Evaluation and Classification Program (DECP).
