Harper CE, Hudson JS, Tidwell K, Boswell R, Yong HL, Maxwell AJ. Implementation of the first comprehensive state oral fluid drug testing program for roadside screening and laboratory testing in DUID cases-A 5-year review. J Anal Toxicol 2023; 47:694-702. [PMID: 37526020 DOI: 10.1093/jat/bkad051] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2023] [Revised: 06/07/2023] [Accepted: 07/31/2023] [Indexed: 08/02/2023] Open
Abstract
Oral fluid (OF) is a valuable specimen for driving under the influence of drugs (DUID) applications. This study demonstrates the implementation of the first comprehensive OF drug testing program in the United States, including approved roadside screening OF devices for law enforcement and validated liquid chromatography-tandem mass spectrometry (LC-MS-MS) confirmation methods. Three roadside OF screening devices were evaluated: the Dräger DrugTest® 5000, Abbott SoToxa®, and Randox Evidence MultiSTAT™. Two qualitative LC-MS-MS confirmation methods were validated per ASB Standard 036. The first method utilized an automated dispersive pipette extraction extraction using Integra and Hamilton STARlet platforms for drugs of abuse. The second method used a liquid-liquid extraction to detect cannabinoids. The prevalence of drugs in blood and OF was monitored over 5 years of casework. Calibration curves were analyzed with each batch to monitor OF concentrations for research purposes. Three roadside OF screening devices were deemed fit for purpose. Devices demonstrated appropriate sensitivity, specificity, positive and negative predictive values, and accuracy above 80% for targeted drugs except for benzodiazepines (DrugTest® 5000) and amphetamine (SoToxa®). The validated LC-MS-MS OF confirmation methods met the National Safety Council-recommended cutoffs for 18/21 (86%) of the targets. Over 5 years of casework, THC and cocaine were detected at a positivity rate of 90% and 97% in OF versus 75% and 44% in blood, respectively. OF:blood ratios exceeded unity for parent drugs. Median concentrations of THC in OF and blood were 31 and 3.5 ng/mL, respectively. OF is a viable alternative or supplemental specimen for DUID investigations. Collecting OF close to the driving event increases the opportunity to identify pharmacologically active substances, and when combined with blood analysis results, an elevated OF:blood ratio provides valuable information for DUID investigation purposes.

[PMID: 37603111 DOI: 10.1080/15389588.2023.2246163] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/14/2023] [Revised: 08/05/2023] [Accepted: 08/05/2023] [Indexed: 08/22/2023]
Abstract
OBJECTIVE This study aimed to measure the prevalence of drugs of abuse (DOA) among the goods carriage drivers associated with the southern State of India, Kerala. METHODS Point-of-collection testing (POCT) of oral fluid collected from the participants (n = 249) was done using the Evidence MultiSTAT DOA Oral Fluid II Assay kits and the Evidence MultiSTAT analyzer. RESULTS Out of the total samples, 53 (21.29%) were positive for one or more DOA. A high prevalence of tetrahydrocannabinol (THC) (10.04%) and synthetic cannabinoids were detected in the samples. The use of ketamine, alpha-PVP, LSD, methamphetamine, opiate, 6-MAM, benzodiazepines I, methadone, PCP, tramadol, and amphetamine was also detected and their frequency of use ranged between 4.02 and 0.80%. An association between drug abuse and distance of travel was found in drivers in this study, χ2 (5, N = 249) = 123.5, p < 0.001. Confirmatory analysis using ultra-high performance liquid chromatography-tandem mass spectrometry showed excellent agreement with the results of the screening test. CONCLUSIONS This was the first study conducted among drivers in India for the detection of DOA. Tetrahydrocannabinol (THC) was used more by the goods carriage drivers associated with Kerala State, India. The use of psychoactive substances significantly increased with the distance of travel. Point-of-collection testing (POCT) by the biochip array technology is an efficient method for the detection of these substances.

Abstract
Drug impaired driver detection is a critical element of traffic safety. However, shifting drug use patterns over time and geography may limit long-term reliability of assay-based screening tools. In this work, we compare qualitative results from the Abbott SoToxa® oral fluid (OF) screening device to Quantisal™ OF and whole blood. Our objective was to examine these three qualitative toxicological approaches, scope applicability of OF collection at the roadside, and compare to a previous analysis of SoToxa® in Wisconsin. OF specimens were screened with the SoToxa® for six drugs or drug classes including amphetamine, benzodiazepines, cocaine, methamphetamine, opioids, and tetrahydrocannabinol (THC). OF and blood specimens were collected from 106 participants. Quantisal™ OF and blood specimens were screened for drugs on ultra-performance liquid chromatography coupled to quadrupole time-of-flight high-resolution mass spectrometry (UPLC-QToF-HRMS) using a data independent acquisition mode. UPLC-QToF-HRMS data was compared to comprehensive spectral libraries and drugs were qualitatively identified. Drug Recognition Expert evaluations were performed, and face sheets submitted for 21 participants in this work. In general, the SoToxa® results were consistent with the combined qualitative results observed in Quantisal™ OF specimens and whole blood specimens. Limitations were uncovered for benzodiazepines, opioids, and THC. The SoToxa® benzodiazepine assay has high cutoff concentrations for diazepam and clonazepam, limiting its sensitivity and positive predictive value when considering these drugs. SoToxa® opioid screening did not detect fentanyl, which is increasingly prevalent among drug users. Finally, ∆9-THC and its major metabolite 11-nor-9-carboxy-∆9-THC are lipophilic, limiting partitioning into oral fluid. Despite these limitations, the SoToxa® instrument may be useful in assisting law enforcement with identifying individuals driving under the influence of drugs and establishing probable cause at roadside for making impaired driving arrests. Furthermore, Quantisal™ OF may be useful as screening specimens due to their ease of collection and results consistent with whole blood.

Roadside Drug Testing Approaches. Molecules 2021; 26:molecules26113291. [PMID: 34072538 PMCID: PMC8199318 DOI: 10.3390/molecules26113291] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2021] [Revised: 05/21/2021] [Accepted: 05/26/2021] [Indexed: 01/01/2023] Open
Abstract
The purpose of this review is to present an overview of roadside drug testing, driving enforcement, and drunk/drug driving detection around the world. Drunk and drug driving is a severe problem, not only in the UAE, but also around the world. This has important implications for road safety as drunk or drug driving may increase the chances of a driver’s involvement in a road crash when compared to a drug-free driver. Recently, due to increases in drug-impaired drivers’ crash involvement, many mobile roadside drug testing devices have been introduced to the market. These devices use oral fluid, urine or blood matrices. These are on-the-spot tests, which are easy to use and are applied by law enforcement agencies and the public. Law enforcement agencies most commonly use oral fluid to detect the presence of illicit drugs in drivers. This review discusses all the available devices in the market used by the authorities. It also describes the type of drugs widely abused by drivers along with behavioral testing methods. The different types of matrices used for roadside drug testing are also evaluated. Sample collection, storage, and pre-treatment methods are discussed, followed by the confirmatory analysis of positive samples. This article will significantly help law enforcement agencies compare and evaluate all the reliable roadside testing devices and new emerging confirmatory devices available to them in the market. This will help them make an informed decision on which device to adapt to their individual needs.

Abstract
The collection and analysis of drugs in oral fluid (OF) at the roadside has become more feasible with the introduction of portable testing devices such as the Alere™ DDS®2 Mobile Test System (DDS®2). The objective of this study was to compare the on-site results for the DDS®2 to laboratory-based confirmatory assays with respect to detection of drugs of abuse in human subjects. As part of a larger Institutional Review Board approved study, two OF samples were collected from each participant at a music festival in Miami, FL, USA. One OF sample was field screened using the DDS®2, and a confirmatory OF sample was collected using the Quantisal™ OF collection device and submitted to the laboratory for testing. In total, 124 subjects participated in this study providing two contemporaneous OF samples. DDS®2 field screening yielded positive results for delta-9-tetrahydrocannabinol (THC) (n = 27), cocaine (n = 12), amphetamine (n = 3), methamphetamine (n = 3) and benzodiazepine (n = 1). No opiate-positive OF samples were detected. For cocaine, amphetamine, methamphetamine and benzodiazepines, the DDS®2 displayed sensitivity, specificity and accuracy of 100%. For THC, the DDS®2 displayed sensitivity of 90%, specificity of 100% and accuracy of 97.5%, when the threshold for confirmation matched that of the manufacturers advertised cut-off. When this confirmatory threshold was lowered to the analytical limit of detection (i.e., 1 ng/mL), apparent device performance for THC was poorer due to additional samples testing positive by confirmatory assay that had tested negative on the DDS®2, demonstrating a need for correlation between manufacturer cut-off and analytical reporting limit. These results from drug-using subjects demonstrate the value of field-based OF testing, and illustrate the significance of selecting an appropriate confirmation cut-off concentration with respect to performance evaluation and detection of drug use.

Abstract
Background In the context of road safety, this study aims to examine the prevalence of drug use in a random sample of drivers. Methods A stratified probabilistic sample was designed to represent vehicles circulating on non-urban roads. Random drug tests were performed during autumn 2014 on 521 drivers in Catalonia (Spain). Participation was mandatory. The prevalence of drug driving for cannabis, methamphetamines, amphetamines, cocaine, opiates and benzodiazepines was assessed. Results The overall prevalence of drug use is 16.4% (95% CI: 13.9; 18.9) and affects primarily younger male drivers. Drug use is similarly prevalent during weekdays and on weekends, but increases with the number of occupants. The likelihood of being positive for methamphetamines is significantly higher for drivers of vans and lorries. Conclusions Different patterns of use are detected depending on the drug considered. Preventive drug tests should not only be conducted on weekends and at night-time, and need to be reinforced for drivers of commercial vehicles. Active educational campaigns should focus on the youngest age-group of male drivers.

Abstract
The use of point-of-collection testing (POCT) devices for drugs of abuse in oral fluid (OF) is an advantageous tool that has been used for different purposes-particularly traffic enforcement. However, even with the widespread report of cocaine consumption, the reliability of POCT devices has been reported in different magnitudes. This study evaluated the reliability of two POCT devices for the detection of cocaine in OF samples of 110 cocaine users: (i) the DDS2™ (cutoff = 30 ng/mL) and (ii) the Multi-Drugs Multi-Line-Twist Screen Test Device™ (MDML) (cutoff = 20 ng/mL). Results of the screening tests were compared with a Liquid Chromatography-Mass Spectrometry (LC-MS) assay. Sensitivity, specificity and accuracy of DDS2™ were 100, 77.77 and 80% when compared with LC-MS with a cutoff of 30 ng/mL, and 88.89, 89.15 and 89.09% with a cutoff of 10 ng/mL. The MDML™ device achieved sensitivity, specificity and accuracy of 100, 65.6 and 70.9% when compared with LC-MS with a cutoff of 20 ng/mL, and 92.6, 71.1 and 76.6% with a cutoff of 10 ng/mL. When compared with a 10 ng/mL cutoff, the DDS2™ achieved reliability parameters higher than 80%. On the other hand, the MDML™ device did not achieve the minimal recommendation of 80% for all parameters at the same time. Taking into consideration the reliability results showed here, the authors believe that the use of these POCT devices seems to be suitable for cocaine detection in forensic tests only if all positive specimens are further confirmed by a validated method.

Abstract
Abstract
BACKGROUND
Roadside oral fluid (OF) Δ9-tetrahydrocannabinol (THC) detection indicates recent cannabis intake. OF and blood THC pharmacokinetic data are limited and there are no on-site OF screening performance evaluations after controlled edible cannabis.
CONTENT
We reviewed OF and blood cannabinoid pharmacokinetics and performance evaluations of the Draeger DrugTest®5000 (DT5000) and Alere™ DDS®2 (DDS2) on-site OF screening devices. We also present data from a controlled oral cannabis administration session.
SUMMARY
OF THC maximum concentrations (Cmax) were similar in frequent as compared to occasional smokers, while blood THC Cmax were higher in frequent [mean (range) 17.7 (8.0–36.1) μg/L] smokers compared to occasional [8.2 (3.2–14.3) μg/L] smokers. Minor cannabinoids Δ9-tetrahydrocannabivarin and cannabigerol were never detected in blood, and not in OF by 5 or 8 h, respectively, with 0.3 μg/L cutoffs. Recommended performance (analytical sensitivity, specificity, and efficiency) criteria for screening devices of ≥80% are difficult to meet when maximizing true positive (TP) results with confirmation cutoffs below the screening cutoff. TPs were greatest with OF confirmation cutoffs of THC ≥1 and ≥2 μg/L, but analytical sensitivities were <80% due to false negative tests arising from confirmation cutoffs below the DT5000 and DDS2 screening cutoffs; all criteria were >80% with an OF THC ≥5 μg/L cutoff. Performance criteria also were >80% with a blood THC ≥5 μg/L confirmation cutoff; however, positive OF screening results might not confirm due to the time required to collect blood after a crash or police stop. OF confirmation is recommended for roadside OF screening.

Abstract
Traffic accidents are responsible for 1.25 million deaths worldwide and are the most common cause of death among those aged 15-29 years. In Brazil, traffic accidents caused more than 44,000 deaths in 2014. The use of psychoactive drugs is an important risk factor for being involved in traffic accidents. Previous studies have found that psychoactive substances are commonly used by truck drivers in Brazil to maintain their extensive work schedule and stay awake while driving during nighttime hours. The state of Sao Paulo is one of the most important states regarding goods transportation. Important highways cross through Sao Paulo to other regions from Brazil and to other countries in Latin America. This study aims to determine the prevalence of illicit drug use by truck drivers in the state of Sao Paulo through toxicological analyses of oral fluid. Truck drivers were randomly stopped by police officers on federal roads during morning hours. Oral fluid samples were collected using the Quantisal™ device. In addition, a questionnaire concerning sociodemographic characteristics and health information was administered. Oral fluid samples were screened for amphetamine, cocaine, and tetrahydrocannabinol (Δ9-THC) by ELISA and the confirmation was performed using ultra performance liquid chromatography with tandem mass spectrometry detection (UPLC-MS/MS). Of the 764 drivers stopped, 762 agreed to participate. The participants were driving an average of 614km and 9.4h a day. Of the total samples, 5.2% (n=40) tested positive for drugs. Cocaine was the most frequently found drug (n=21), followed by amphetamine (n=16) and Δ9-THC (n=8). All drivers were men with an average age of 42.5 years. With these results we were able to verify that many truck drivers were still consuming psychoactive drugs while driving, and cocaine was the most prevalent one. This reinforces the need for preventive measures aimed at controlling the use of illicit drugs by truck drivers in Brazil.

Abstract
Oral fluid has become an important matrix for drugs of abuse analysis. These days the applicability is challenged by the fact that an increasing number of new psychoactive drugs are coming on the market. Synthetic cannabinoids and synthetic cathinones have been the main drug classes, but the diversity is increasing and other drugs like piperazines, phenethylamines, tryptamines, designer opioids and designer benzodiazepines are becoming more prevalent. Many of the substances are very potent, and low doses ingested will lead to low concentrations in biological media, including oral fluid. This review will highlight the phenomenon of new psychoactive substances and review methods for oral fluid drug testing analysis using on-site tests, immunoassays and chromatographic methods.
