The International Drug Evaluation & Classification Program

The International Drug Evaluation & Classification Program

The Drug Evaluation and Classification Program is recognized by all fifty states in the U.S., Canada, 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).

NTSB 2022 Study on Alcohol, Drugs, Impaired Driving and Crash Risk

In a recent study published by the National Transportation Safety Board (NTSB), researchers looked at the prevalence of multiple drugs and drug categories associated with impaired driving performance and increased crash risk. NTSB surmises that drug data in national-level databases can be difficult to estimate drug prevalence among drivers. Their study found that between 71% and 99% of drivers in the five populations studied tested positive for one or more potentially impairing drugs, and about half of the drivers tested positive for more than one category of drug. Alcohol and cannabis were the two most commonly detected drugs across all populations studied.
