The Oregon Drug Evaluation and Classification (DEC) Program is managed and coordinated by the Oregon State Police and has been since the inception of the program in 1995. The DEC Program trains police officers to recognize impairment in drivers under the influence of drugs other than, or in addition to, alcohol. Oregon is one of 46 states, including the District of Columbia, participating in the program. The DEC Program is under the national guidance and direction of the International Association of Chiefs of Police (IACP) and supported by the National Highway Traffic Safety Administration (NHTSA). Sergeant Evan Sether is Oregon's DEC Program State Coordinator. Oregon currently has 180 certified Drug Recognition Experts. The mission of the Oregon DEC Program is to reduce the number of drug and alcohol-related crashes and incidents by improving law enforcement detection skills in identifying persons under the influence of drugs, alcohol, and other psychoactive substances.
