Components of the Drug Evaluation and Classification Procedure The Drug Influence Evaluation The DEC procedure is a systematic and standardized method of examining a subject to determine: • Whether the subject is impaired, and if so, • Whether the impairment is caused by drugs or a medical condition. • And if drugs, the category (or categories) of drugs that is/are the likely cause of the subject’s impairment. The process is systematic in that it is based on a careful assessment of a variety of observable signs and symptoms that are known to be reliable indicators of drug impairment. • Some of these observable signs and symptoms relate to the subject’s appearance. • Some of these observable signs and symptoms relate to the subject’s behavior. • Some relate to the subject’s performance of carefully administered psychophysical tests. HS 172 R5/13 2 of 41 Session 4 – Overview of Drug Recognition Expert Procedures Notes:__________________________________________________ The Drug Influence Evaluation _______________________________________________________ (Cont.) _______________________________________________________ Systematic and Standardized Process _______________________________________________________ Why is it so important to perform the drug _______________________________________________________ influence evaluation in exactly the same way, every time? _______________________________________________________ _______________________________________________________ _______________________________________________________ _______________________________________________________ Drug Recognition Expert Course 4-4 Drugs impair the subject’s ability to control his or her mind and body. • Psychophysical tests can disclose that the subject’s ability to control mind and body is impaired. • The specific manner in which the subject performs the psychophysical tests may help indicate the category or categories of drugs causing the impairment. • Some of the observable signs and symptoms relate to the subject’s automatic responses to the specific drugs that are present. • All of these reliable indicators are examined and carefully considered before a judgment is made concerning what categories of drugs are affecting the subject. The evaluation is standardized in that it is administered the same way, every time. HS 172 R5/13 3 of 41 Session 4 – Overview of Drug Recognition Expert Procedures Notes:_______________________________________________ The Drug Influence Evaluation (Cont.) _____________________________________________________ _____________________________________________________ Systematic and Standardized Process _____________________________________________________ There my be times when the DRE may be unable to complete each step of the evaluation, i.e., _____________________________________________________ injuries, uncooperative subject, equipment failure, etc. _____________________________________________________ _____________________________________________________ _____________________________________________________ 4-5 _____________________________________________________ Drug Recognition Expert Course • Standardization helps to ensure that no mistakes are made. • No examinations are left out. • No extraneous or unreliable “indicators” are included. • Standardization helps to promote professionalism among drug recognition experts. • Standardization helps to secure acceptance in court. In such cases, the DRE may still be able to form an opinion based upon the evidence obtained. State v. Cammack, 1997 WL 104913 (Minnesota Ct. Appeals, 1997) ruled that a DRE need not complete the entire 12-step evaluation for an opinion to be admissible so long as there is sufficient admissible evidence.

  • The Drug Recognition Expert and Impaired Driving Enforcement
    The Drug Recognition Expert and Impaired Driving Enforcement by Sgt. Jamie Boothe School of Law Enforcement Supervision (SLES) Session XXXIV Criminal Justice Institute November 20, 2009 The Drug Recognition Expert and Impaired Driving Enforcement It is a sad but persistent truth that impaired driving impacts the lives of thousands of Americans each and every year. Whether it is the loss of a loved one, a debilitating, life-altering injury, or financial crises brought on by skyrocketing medical costs, there is no escape from the fact that impaired driving changes lives. The only solution to the problem is targeted enforcement aimed at reducing the number of impaired drivers on the highways, and insuring that those who engage in this type of conduct are held accountable for their actions. The Drug Recognition Expert, hereafter referred to simply as the DRE, is an important resource in our efforts to reduce impaired driving, and ultimately save lives. As a DRE, I take great pride and satisfaction in knowing that I am doing everything possible to help in this enormous task. The majority of the information contained within the body of this paper is taken from my own knowledge base and first hand experience in dealing with drug-impaired drivers. To understand how the DRE fulfills their role in impaired driving enforcement, I will examine the prevalence of drug use in society and its impact on traffic safety, the origin and development of the Drug Evaluation and Classification program, how drugs cause impairment, categories of drugs, and the standardized drug evaluation process used by all DREs to determine impairment in drivers.
