Using Oral Fluid in DUID Enforcement Cases


Presented by Dr. Barry K. Logan, PhD, DABFT, NMS Labs Vice President of Forensic Science Initiatives and Chief of Forensic Toxicology at the IACP-DRE Conference, July 2014

DRE_2014_OF.jpgThe use of oral fluid as a matrix for the detection of drugs in drivers has been gaining interest and acceptance in the last few years. While law enforcement agencies in several countries have implemented saliva collection and analysis, communities in the United States are gradually conducting field studies in various driving populations. This session will present data to support the use of oral fluid as a biological sample for detecting drugs in drivers; provide results from research projects throughout the country; and offer guidance and protocols for the performance of field studies using oral fluid. The presenters are predominantly members of the newly established Oral Fluid Subgroup of the SOFT/AAFS DUID Committee, which is charged with providing information and guidance to the forensic community on this issue.

The Principles of Pharmacology and Drug Effects – Cannabinoids


Presented by Dr. Barry K. Logan, PhD, DABFT, NMS Labs Vice President of Forensic Science Initiatives and Chief of Forensic Toxicology at the IACP-DRE Conference, July 2014

DRE_2014_Cannabinoids.jpgCannabis has been around for over 3,000 years as a medical drug and euphoriant. It is a significant factor in today’s society and is the most widely used recreational drug after alcohol and tobacco, with 38% of adults admitting to having tried it. Today’s marijuana is potent, and in many states is decriminalized or even legalized. This presentation will consider the history of cannabis, what we learned about its pharmacology, the intended effects and undesirable side effects and how these effects impact driving. We will look at the symptoms in the DRE matrix and SFSTs, and how they arise, and consider the similarities and differences between cannabis and the synthetic cannabinoids. The presentation should help you feel more confident in court about what’s behind the basis for a call for the cannabis category.

The Principles of Pharmacology and Drug Effects – CNS Depressants


Presented by Dr. Barry K. Logan, PhD, DABFT, NMS Labs Vice President of Forensic Science Initiatives and Chief of Forensic Toxicology at the IACP-DRE Conference, July 2014

DRE_2014_CNS.jpgAlcohol is the prototypical CNS depressant drug and, fortunately for us, most jurors have some first-hand experience with the effects of its overuse, either by themselves or someone they know and love. There are several drug classes with CNS depressant properties, including seizure medications, muscle relaxants, sleep aids, and allergy medications. Most act through the GABA system and produce effects quite similar to alcohol including sedation, loss of motor skills, poorer judgment and reasoning and slowed reaction time. This presentation will explain the GABA system and what is known about the relationship between these effects and driving performance.
