The ability to identify drugged drivers at roadside started back in the 1970s when the Los Angeles Police Department established the Drug Evaluation and Classification (DEC) Program. The purpose of the program is to train officers to become Drug Recognition Experts (DREs) who are capable of identifying drug impairment. Officers are required to go through three phases of training totaling more than 100 hours before they are eligible to receive DRE field certification.

The DEC program goes beyond the Standardized Field Sobriety Test (SFST) training that most officers receive. DREs use a standardized 12-step protocol that allows them to determine whether a suspect is impaired, if that impairment is caused by drugs or can be attributed to a medical condition, and the category of drug(s) that are the cause of the impairment.

All fifty states, Canada, and the United Kingdom have implemented the DEC program. The above map shows how many certified DREs were present in each state in 2014 (the most recent year for which the International Association of Chiefs of Police (IACP) has released data).

Responsibility.org is committed to increasing the number of officers trained to identify drugged drivers. We have partnered with the Governors Highway Safety Association to fund DRE training in 2016 and 2017.

**Drunkenness is not considered a crime in some states; therefore, the figures may vary widely from state to state

Limited, incomplete, or no data were reported by the District of Columbia, Florida, Illinois, and New York in the 2016 Uniform Crime Report. Data should be used with caution and should not be compared to other states or previous year data.

Note: Because the number of agencies submitting arrest data varies from year to year, users are cautioned about making direct comparisons between 2016 arrest totals and those published in previous years’ editions of Crime in the United States. Further, arrest figures may vary widely from state to state because some Part II crimes of the Uniform Crime Report are not considered crimes in some states.
