Wennberg E, Windle SB, Filion KB, Thombs BD, Gore G, Benedetti A, Grad R, Ells C, Eisenberg MJ. Roadside screening tests for cannabis use: A systematic review. Heliyon 2023; 9:e14630. [PMID: 37064483 PMCID: PMC10102219 DOI: 10.1016/j.heliyon.2023.e14630] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2022] [Revised: 12/20/2022] [Accepted: 03/13/2023] [Indexed: 04/04/2023] Open
Abstract
As more countries legalize recreational cannabis, roadside screening programs are imperative to detect and deter driving under the influence of cannabis. This systematic review evaluated roadside screening tests for cannabis use. We searched six databases (inception-March 2020) and grey literature sources for primary studies evaluating test characteristics of roadside screening tests for cannabis use compared to laboratory tests for cannabinoids in blood or oral fluid. The synthesis was focused on sensitivity and specificity of delta-9-tetrahydrocannabinol (THC) detection. 101 studies were included. Oral fluid tests were higher in specificity and lower in sensitivity compared to urine tests when evaluated against blood laboratory tests. Oral fluid tests were higher in sensitivity and similar in specificity compared to observational tests when evaluated against blood and oral fluid laboratory tests. Sensitivity was variable among oral fluid tests; two instrumented immunoassays (Draeger DrugTest 5000 [5 ng/mL THC cut-off] and Alere DDS 2 Mobile Test System) appeared to perform best, but definitive conclusions could not be drawn due to imprecise estimates. Specificities were similar. Overall, oral fluid tests showed the most promise for use in roadside screening for blood THC levels over legal limits; their continued development and testing are warranted. Urine tests are generally inadvisable, and observational tests require sensitivity improvements.

Liu C. Exploration of the longitudinal trend of DUI crashes in Pennsylvania, USA (2008 to 2019). TRAFFIC INJURY PREVENTION 2021; 22:593-598. [PMID: 34570629 DOI: 10.1080/15389588.2021.1975687] [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: 02/04/2021] [Revised: 08/29/2021] [Accepted: 08/29/2021] [Indexed: 06/13/2023]
Abstract
OBJECTIVE This study aims to explore the longitudinal trends of DUI crashes in Pennsylvania, USA to provide insights for making the long-term DUI countermeasures. METHODS Crash data of Pennsylvania from 2008 to 2019 are collected from the Pennsylvania Department of Transportation. DUI crashes are divided into alcohol-impaired, drug-impaired, and alcohol-drug-impaired ones in the analysis. The linear regression models are adopted to check whether traffic crashes had significantly changed over time. RESULTS Alcohol-impaired crashes decreased but drug-impaired crashes increased in the study period. Drugged driving is increasingly more deadly compared to drunk driving, and alcohol-drug-impaired crashes are the deadliest. Besides, illicit drugs dominate drug-impaired crashes now, drugged driving is increasing in rural areas, and older drivers are overwhelmingly involved in DUI crashes. CONCLUSIONS The growth of drug-impaired crashes, especially illicit drug-impaired crashes, raises new concerns to the proposal of marijuana legalization in Pennsylvania, where recreational use of marijuana is currently prohibited. The decreasing trend of alcohol-impaired crashes is suggestive of the success of the long-term crackdown to drunk driving and implies the necessity of developing the uniform and handy roadside drug test devices. Besides, rural areas and older drivers should be paid special attention to deter DUI in the context of urbanization and population aging.

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
With recent changes in the legalization of cannabis around the world, there is an urgent need for rapid, yet sensitive, screening devices for testing drivers and employees under the influence of cannabis at the roadside and at the workplace, respectively. Oral fluid lateral flow immunoassays (LFAs) have recently been explored for such applications. While LFAs offer on-site, low-cost and rapid detection of tetrahydrocannabinol (THC), their nominal detection threshold is about 25 ng/ml, which is well above the 1-5 ng/ml per se limits set by regulations. In this paper, we report on the development of a thermo-photonic imaging system that utilizes the commercially available low-cost LFAs but offers detection of THC at unprecedented low concentrations. Our reader technology examines photothermal responses of gold nanoparticles (GNPs) in LFA through lock-in thermography (LIT). Our results (n = 300) suggest that the demodulation of localized surface plasmon resonance responses of GNPs captured by infrared cameras allows for detection of THC concentrations as low as 2 ng/ml with 96% accuracy. Quantification of THC concentration is also achievable with our technology through calibration.

Reliability of point-of-collection testing devices for drugs of abuse in oral fluid: A systematic review and meta-analysis. J Pharm Biomed Anal 2017; 143:77-85. [PMID: 28577420 DOI: 10.1016/j.jpba.2017.05.021] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2017] [Revised: 05/06/2017] [Accepted: 05/11/2017] [Indexed: 11/18/2022]
Abstract
Point-of-collection testing (POCT) devices for drugs of abuse are used to screen for the presence of psychoactive substances (PAS) in different types of settings and environments. However, these quick and advantageous tools also present disadvantages, including low-reliability measures in comparison to chromatographic assays. Therefore, this article presents a systematic review and meta-analysis of studies evaluating the reliability of measurements of PAS detection in oral fluid using POCT devices. The reliability measures for detection of the five most important drug classes - cocaine, amphetamines, benzodiazepines, cannabinoids and opioids, are reported. The article also presents a subgroup analysis considering the reliability estimates for the different POCT devices that were evaluated by the studies contemplated in the review. A discussion considering the strengths and limitations of POCT techniques was performed in order to guide policymakers, traffic agents and other professionals who also conduct such tests. The use of POCT devices often involves legal and moral aspects of the subjects tested, which demands critical evaluation of these devices before they are implemented in different settings.

Abstract
Laboratory testing for drugs of abuse has become standard practice in many settings both forensic and clinical. Urine is the predominant specimen, but other specimens are possible including hair, nails, sweat, and oral fluid. Point-of-care test kits provide for rapid analysis at the site where specimens are collected allowing for immediate action on the results. POCT is based on immunochromatography where the drug in the patient's sample competes with drug and antibody conjugates in the test to develop or block the development of a colored line. Most POCTs are visually interpreted in a few minutes. The potential for false positives is possible due to drug cross-reactivity with the antibodies in the test. False negatives are also possible due to dilution of the sample and the potential for adulteration or sample substitution by the patient. POCT shows more variability than central laboratory testing because of the variety of operators involved in the testing process, but POCT has good agreement for most tests with mass spectrometry provided comparable cutoffs and cross-reactivity of drugs/metabolites are considered. Validation of the test performance with the intended operators will identify potential interferences and operational issues before implementing the test in routine practice. POCT offers faster turnaround of test results provided the limitations and challenges of the test are considered.

Abstract
The reliability of DrugWipe 5A on site test for principal drugs of abuse (cannabis, amphetamines, cocaine, and opiates) detection in oral fluid was assessed by comparing the on-site results with headspace solid-phase microextraction (HS-SPME) gas chromatography-mass spectrometry (GC-MS) analysis on samples extracted by the device collection pad. Oral fluid samples were collected at recreational settings (e.g., discos, pubs, and music bars) of Rome metropolitan area. Eighty-three club goers underwent the on-site drug screening test with one device. Independently from the result obtained, a second device was used just to collect another oral fluid sample subsequently extracted and analyzed in the laboratory following HS-SPME procedure, gas chromatographic separation by a capillary column, and MS detection by electron impact ionization. DrugWipe 5A on-site test showed 54 samples (65.1%) positive to one or more drugs of abuse, whereas 75 samples (90.4%) tested positive for one or more substances following GC-MS assay. Comparing the obtained results, the device showed sensitivity, specificity, and accuracy around 80% for amphetamines class. Sensitivity (67 and 50%) was obtained for cocaine and opiates, while both sensitivity and accuracy were unsuccessful (29 and 53%, resp.) for cannabis, underlying the limitation of the device for this latter drug class.

Abstract
OBJECTIVE There is currently a gap in on-site drug of abuse monitoring. Current detection methods involve invasive sampling of blood and urine specimens, or collection of oral fluid, followed by qualitative screening tests using immunochromatographic cartridges. While remote laboratories then may provide confirmation and quantitative assessment of a presumptive positive, this instrumentation is expensive and decoupled from the initial sampling making the current drug-screening program inefficient and costly. The authors applied a noninvasive oral fluid sampling approach integrated with the in-development chip-based Programmable bio-nano-chip (p-BNC) platform for the detection of drugs of abuse. METHOD The p-BNC assay methodology was applied for the detection of tetrahydrocannabinol, morphine, amphetamine, methamphetamine, cocaine, methadone and benzodiazepines, initially using spiked buffered samples and, ultimately, using oral fluid specimen collected from consented volunteers. RESULTS Rapid (∼10min), sensitive detection (∼ng/mL) and quantitation of 12 drugs of abuse was demonstrated on the p-BNC platform. Furthermore, the system provided visibility to time-course of select drug and metabolite profiles in oral fluids; for the drug cocaine, three regions of slope were observed that, when combined with concentration measurements from this and prior impairment studies, information about cocaine-induced impairment may be revealed. CONCLUSIONS This chip-based p-BNC detection modality has significant potential to be used in the future by law enforcement officers for roadside drug testing and to serve a variety of other settings, including outpatient and inpatient drug rehabilitation centers, emergency rooms, prisons, schools, and in the workplace.

Anal Bioanal Chem 2014; 406:4117-28.

Abstract
Oral fluid (OF) enables non-invasive sample collection for on-site drug testing, but performance of on-site tests with occasional and frequent smokers' OF to identify cannabinoid intake requires further evaluation. Furthermore, as far as we are aware, no studies have evaluated differences between cannabinoid disposition among OF collection devices with authentic OF samples after controlled cannabis administration. Fourteen frequent (≥4 times per week) and 10 occasional (less than twice a week) adult cannabis smokers smoked one 6.8% ∆(9)-tetrahydrocannabinol (THC) cigarette ad libitum over 10 min. OF was collected with the StatSure Saliva Sampler, Oral-Eze, and Draeger DrugTest 5000 test cassette before and up to 30 h after cannabis smoking. Test cassettes were analyzed within 15 min and gas chromatography-mass spectrometry cannabinoid results were obtained within 24 h. Cannabinoid concentrations with the StatSure and Oral-Eze devices were compared and times of last cannabinoid detection (t(last)) and DrugTest 5000 test performance were assessed for different cannabinoid cutoffs. 11-nor-9-Carboxy-THC (THCCOOH) and cannabinol concentrations were significantly higher in Oral-Eze samples than in Stat-Sure samples. DrugTest 5000 t(last) for a positive cannabinoid test were median (range) 12 h (4-24 h) and 21 h (1- ≥ 30 h) for occasional and frequent smokers, respectively. Detection windows in screening and confirmatory tests were usually shorter for occasional than for frequent smokers, especially when including THCCOOH ≥20 ng L(-1) in confirmation criteria. No differences in t(last) were observed between collection devices, except for THC ≥2 μg L(-1). We thus report significantly different THCCOOH and cannabinol, but not THC, concentrations between OF collection devices, which may affect OF data interpretation. The DrugTest 5000 on-site device had high diagnostic sensitivity, specificity, and efficiency for cannabinoids.

Abstract
BACKGROUND Although screening, brief intervention, and referral to treatment (SBIRT) is an evidence-based technique that, in some health-care settings, has been shown to cost-effectively reduce alcohol and drug use, research on the efficacy of SBIRT among criminal offender populations is limited. Such populations have a high prevalence of drug and alcohol use but limited access to intervention, and many are at risk for post-release relapse and recidivism. Thus, there exists a need for treatment options for drug-involved offenders of varying risk levels to reduce risky behaviors or enter treatment. METHODS/DESIGN This protocol describes an assessment of SBIRT feasibility and effectiveness in a criminal justice environment. Eight-hundred persons will be recruited from a large metropolitan jail, with the experimental group receiving an intervention depending on risk level and the control group receiving minimal intervention. The intervention will assess the risk level for drug and alcohol misuse by inmates, providing those at low or medium risk a brief intervention in the jail and referring those at high risk to community treatment following release. In addition, a brief treatment (eight-session) option will be available. Using data from a 12-month follow-up interview, the primary study outcomes are a reduction in drug and alcohol use, while secondary outcomes include participation in treatment, rearrest, quality of life, reduction in HIV risk behaviors, and costs of SBIRT. EXPECTED VALUE Individual reductions in alcohol and drug use can have significant effects on public health and safety when observed over a large population at risk for substance-use problems. With wider dissemination statewide or nationwide, a relatively low-cost intervention such as SBIRT could offer demonstrated benefits in this population.

Abstract
A preliminary field evaluation of a second-generation handheld oral fluid testing device, the Alere DDS2 Mobile Test System (DDS2), is described. As part of a larger study, drivers were randomly stopped at various locations across California (in 2012) and asked to submit voluntarily to a questionnaire regarding their drug and alcohol use, a breath alcohol test and collection of oral fluid with the Quantisal device. The Quantisal-collected oral fluid samples were sent for laboratory-based analyses. At one location, 50 drivers were asked to submit an additional oral fluid sample using the DDS2 collection device; these samples were analyzed by using the DDS2 mobile test system. Thirty-eight donors (76%) provided specimens that were successfully run on the mobile system; in 12 cases (24%), the device failed to provide a valid result. Thirty-two of the 38 collected samples were negative for all drugs; five were positive for tetrahydrocannabinol and one was positive for methamphetamine using the mobile device. These results corresponded exactly with the laboratory-based results from the Quantisal oral fluid collection.

Abstract
BACKGROUND Oral fluid (OF) testing offers noninvasive sample collection for on-site drug testing; however, to date, test performance for Δ(9)-tetrahydrocannabinol (THC) detection has had unacceptable diagnostic sensitivity. On-site tests must accurately identify cannabis exposure because this drug accounts for the highest prevalence in workplace drug testing and driving under the influence of drugs (DUID) programs. METHODS Ten cannabis smokers (9 males, 1 female) provided written informed consent to participate in this institutional review board-approved study and smoked 1 6.8%-THC cigarette ad libitum. OF was collected with the Draeger DrugTest(®) 5000 test cassette and Quantisal™ device 0.5 h before and up to 22 h after smoking. Test cassettes were analyzed within 15 min (n = 66), and Quantisal GC-MS THC results obtained within 24 h. Final THC detection times and test performances were assessed at different cannabinoid cutoffs. RESULTS Diagnostic sensitivity, diagnostic specificity, and efficiency at DrugTest 5000's 5 μg/L screening cutoff and various THC confirmation cutoffs were 86.2-90.7, 75.0-77.8, and 84.8-87.9%, respectively. Last detection times were >22 h, longer than previously suggested. Confirmation of 11-nor-9-carboxy-THC, absent in THC smoke, minimized the potential for passive OF contamination and still provided 22-h windows of detection, appropriate for workplace drug testing, whereas confirmation of cannabidiol, and/or cannabinol yielded shorter 6-h windows of detection, appropriate for DUID OF testing. CONCLUSIONS The DrugTest 5000 on-site device provided high diagnostic sensitivity for detection of cannabinoid exposure, and the selection of OF confirmation analytes and cutoffs provided appropriate windows of detection to meet the goals of different drug testing programs.

Abstract
The use of oral fluid (OF) as an alternative matrix for the detection of drugs of abuse has increased over the last decade, leading to the need for a rapid, simple, and reliable on-site OF testing device. Four on-site OF drug testing devices (Dräger DrugTest 5000, Cozart DDS, Mavand Rapid STAT, and Innovacon OrAlert) were evaluated on 408 volunteers at drug treatment centers. UPLC-MS-MS results were used as reference to determine sensitivity, specificity and accuracy for each device, applying Belgian legal confirmation cutoffs for benzoylecgonine, cocaine, and THC (10 ng/mL); morphine and 6-acetylmorphine (5 ng/mL); and amphetamine and 3,4-methylenedioxymethylamphetamine (25 ng/mL). Sensitivity for cocaine was 50%, 50%, 27%, and 11% for DrugTest, OrAlert, Rapid STAT, and DDS 806, respectively. For opiates, sensitivities were 84%, 73%, 77%, and 65%, respectively. For THC, the sensitivities were 81%, 23%, 43%, and 28%, respectively. For amphetamines, the sensitivities were 75%, 33%, 17%, and 67%, respectively. Specificity was >88% for opiates and THC, > 90% for amphetamines, and > 97% for cocaine. All tests showed good specificity. DrugTest had the highest sensitivity, although it was still low for some analytes.

Abstract
In this paper the development of the first direct surface plasmon resonance (SPR) immunoassay for the detection of benzoylecgonine (BZE) is described. Immunosensor chips consisting of a high affinity monoclonal anti-BZE-antibody (anti-BZE-Ab) immobilized at high density to a sensor chip were prepared. First, BZE detection in Hepes buffer was achieved by direct, real time monitoring of the binding between BZE in solution and the surface bound antibody. The detection protocol was based on calibration curves obtained from reaction rate data and end point data analysis of sensorgrams registered after injection of a series of known BZE concentrations over the chips. Moreover, immunosensor accuracy, reproducibility, stability and robustness were tested to demonstrate their good performance as reusable devices. The immunosensor was used for BZE detection in oral fluid (OF) showing that, within 180 s, our immunoassay detects BZE concentrations as low as 4 μg/L in filtered OF-buffer (1:4) samples. This value is remarkably lower than current cut off levels established by the Substance Abuse and Mental Health Services Administration. These results manifest the potential use of this direct SPR immunoassay for the in situ sensitive detection of recent cocaine abuse, of utility in roadside drug OF testing. Moreover, it exemplifies the high potential of direct SPR immunoassays for the rapid, sensitive detection of small molecules in contrast with the more established indirect methods.

Abstract
The performance of eight on-site oral fluid drug screening devices was studied in Belgium, Finland and the Netherlands as a part of the EU-project DRUID. The main objective of the study was to evaluate the reliability of the devices for testing drivers suspected of driving under the influence of drugs (DUID). The performance of the devices was assessed by their ability to detect substances using cut-offs which were set at sufficiently low levels to allow optimal detection of positive DUID cases. The devices were evaluated for the detection of amphetamine(s), cannabis, cocaine, opiates and benzodiazepines when the relevant test was incorporated. Methamphetamine, MDMA and PCP tests that were included in some devices were not evaluated since there were too few positive samples. The device results were compared with confirmation analysis results in oral fluid. The opiates tests appeared to perform relatively well with sensitivity results between 69 and 90%. Amphetamines and benzodiazepines tests had lower sensitivity, although the DrugWipe test evaluated was promising for amphetamine. In particular, it is evident that the cannabis and cocaine tests of the devices still lack sensitivity, although further testing of the cocaine tests is desirable due to the low prevalence and low concentrations encountered in this study.

Abstract
In the past decade much research concerning the impact of cannabis use on road safety has been conducted. More specifically, studies on effects of cannabis smoking on driving performance, as well as epidemiological studies and cannabis-detection techniques have been published. As a result, several countries have adopted driving under the influence of drugs (DUID) legislations, with varying approaches worldwide. A wide variety of bodily fluids have been utilized to determine the presence of cannabis. Urine and blood are the most widely used matrices for DUID legislations. However, more and more publications focus on the usability of oral fluid testing for this purpose. Each matrix provides different information about time and extent of use and likelihood of impairment. This review will focus on the practical aspects of implying a DUID legislation. The pros and cons of the different biological matrices used for Δ9-tetrahydrocannabinol screening and quantification will be discussed. In addition, a literature overview concerning (roadside) cannabinoid detection, as well as laboratory confirmation techniques is given. Finally, we will discuss important issues influencing interpretation of these data, such as oral fluid collection, choice of cut-offs, stability and proficiency testing.

Abstract
Currently, there is need for laboratory-based high-throughput and reliable point-of-care drug screening methodologies. We demonstrate here a chip-based label-free porous silicon (PSi) photonic sensor for detecting opiates in urine. This technique provides a cost-effective alternative to conventional labeled drug screening immunoassays with potential for translation to multiplexed analysis. Important effects of surface chemistry and competitive binding assay protocol on the sensitivity of opiate detection are revealed. Capability to tune sensitivity and detection range over approximately 3 orders of magnitude (18.0 nM to 10.8 muM) was achieved by varying the applied urine specimen volume (100-5 muL), which results in systematic shifts in the competitive binding response curve. A detection range (0.36-4.02 muM) of morphine in urine (15 muL) was designed to span the current positive cutoff value (1.05 muM morphine) in medical opiate urine screening. Desirable high cross-reactivity to oxycodone, in addition to other common opiates, morphine, morphine-3-glucuronide, 6-acetyl morphine, demonstrates an advantage over current commercial screening assays, while low interference with cocaine metabolite was maintained. This study uniquely displays PSi sensor technology as an inexpensive, rapid, and reliable drug screening technology. Furthermore, the versatile surface chemistry developed can be implemented on a range of solid-supported sensors to conduct competitive inhibition assays.

Abstract
Testing for drugs of abuse has become commonplace and is used for a variety of indications. Commonly employed testing methods include immunoassay and chromatography. Testing methods vary in their sensitivity, specificity, time, and cost. While urine remains the most common body fluid used for testing of drugs of abuse, over the last several decades the use of alternative matrices such as blood, sweat, oral fluids, and hair has increased dramatically. Each biological matrix offers advantages and disadvantages for drug testing, and the most appropriate matrix frequently depends on the indications for the drug test. Drugs of abuse that are most commonly tested include alcohol, amphetamines, cannabinoids, cocaine, opiates, and phencyclidine. Testing may involve detection of the parent compound or metabolites and sensitivity, specificity, and reliability of drug testing may vary depending on the drug being tested. Toxicologists have a responsibility to understand the strengths and limitations of testing techniques and matrices to be able to critically evaluate the results of a drug test.

Abstract
Driving under the influence of drugs is a major problem worldwide. At the moment, several countries have adopted a 'per se' legislation to address this problem. One of the key elements in the enforcement process is the possibility of rapid on-site screening tests to take immediate administrative measures. In this study, the reliability of three oral fluid screening devices (Mavand RapidSTAT, Securetec Drugwipe-5(+), and Dräger DrugTest 5000) was assessed by comparing their on-site results with confirmatory GC-MS plasma analysis. Our results demonstrate that for amphetamine screening, the oral fluid on-site devices on the market today are certainly sensitive enough. RapidSTAT, Drugwipe-5(+), and DrugTest 5000 demonstrated respectively a sensitivity of 93%, 100% and 92% for amphetamine/MDMA. For cocaine screening, sensitivities of 75%, 78% and 67% were obtained for the RapidSTAT, Drugwipe-5(+), and DrugTest 5000 devices, respectively. The studied devices were able to detect about 70% of all cannabis users in a roadside setting. However, a newer version of the DrugTest 5000 test cassette demonstrated a sensitivity of 93%, indicating an increased detection of Delta(9)-tetrahydrocannabinol using 'new generation' oral fluid screening tests with lowered cut-offs. Due to these promising results police officers and judicial experts are keen to use oral fluid screening devices. They believe that their ease of use and diminished amount of false positive results in comparison with urine screening will lead to more roadside tests and more appropriate juridical measures.

Abstract
BACKGROUND Oral fluid (OF) is an exciting alternative matrix for monitoring drugs of abuse in workplace, clinical toxicology, criminal justice, and driving under the influence of drugs (DUID) programs. During the last 5 years, scientific and technological advances in OF collection, point-of-collection testing devices, and screening and confirmation methods were achieved. Guidelines were proposed for workplace OF testing by the Substance Abuse and Mental Health Services Administration, DUID testing by the European Union's Driving under the Influence of Drugs, Alcohol and Medicines (DRUID) program, and standardization of DUID research. Although OF testing is now commonplace in many monitoring programs, the greatest current limitation is the scarcity of controlled drug administration studies available to guide interpretation. CONTENT This review outlines OF testing advantages and limitations, and the progress in OF that has occurred during the last 5 years in collection, screening, confirmation, and interpretation of cannabinoids, opioids, amphetamines, cocaine, and benzodiazepines. We examine controlled drug administration studies, immunoassay and chromatographic methods, collection devices, point-of-collection testing device performance, and recent applications of OF testing. SUMMARY Substance Abuse and Mental Health Services Administration approval of OF testing was delayed because questions about drug OF disposition were not yet resolved, and collection device performance and testing assays required improvement. Here, we document the many advances achieved in the use of OF. Additional research is needed to identify new biomarkers, determine drug detection windows, characterize OF adulteration techniques, and evaluate analyte stability. Nevertheless, there is no doubt that OF offers multiple advantages as an alternative matrix for drug monitoring and has an important role in DUID, treatment, workplace, and criminal justice programs.

Abstract
Drug oral fluid analysis was first used almost 30 years ago for the purpose of therapeutic drug monitoring. Since then, oral fluid bioanalysis has become more popular, mainly in the fields of pharmacokinetics, workplace drug testing, criminal justice, driving under the influence testing and therapeutic drug monitoring. In fact, oral fluid can provide a readily available and noninvasive medium, without any privacy loss by the examinee, which occurs, for instance, during the collection of urine samples. It is believed that drug concentrations in oral fluid may parallel those measured in blood. This feature makes oral fluid an alternative analytical specimen to blood, which assumes particular importance in roadside testing, the most published application of this sample. Great improvements in the development of accurate and reliable methods for sample collection, in situ detection devices (on-site drug detection kits), and highly sensitive and specific analytical methods for oral fluid testing of drugs have been observed in the last few years. However, without mass spectrometry-based analytical methods, such as liquid chromatography coupled to mass spectrometry (LC–MS) or tandem mass spectrometry (LC–MS/MS), the desired sensitivity would not be met, due to the low amounts of sample usually available for analysis. This review will discuss a series of published papers on the applicability of oral fluid in the field of analytical, clinical and forensic toxicology, with a special focus on its advantages and drawbacks over the normally used biological specimens and the main technological advances over the last decade, which have made oral fluid analysis of drugs possible.
