Over recent years, the inclusion of hair follicle testing in drug testing has increased. More employers, judicial systems, and substance abuse specialists prefer this over the conventional urine tests. Hair follicle drug testing suits organizations with stringent drug policies, judicial mandates, and probation monitoring, offering the advantage of detecting usage for up to 90 days, secured in a monitored collection process, minimizing options for deception. Yet, for drug screening in the past 5 days, urine testing proves more precise.

Hair testing has become recognized as an effective means for identifying drug and alcohol consumption. Hair retains a prolonged history of substance use by embedding biomarkers in the fibers of the developing hair shaft. When cut near the scalp, hair can offer about a 3-month timeframe for detecting alcohol and drugs. The collection of hair is straightforward, hard to tamper with, and simple to transport.
A 1.5-inch segment consisting of around 200 hair strands (akin to the thickness of a #2 pencil) that is nearest to the scalp will yield 100mg of hair, which is the perfect sample size for both screening and confirmation. For EtG, supplementary tests, and tests exceeding 10 panels, 150mg of the sample is advised. It is advisable to weigh the sample using a jeweler's scale. Should scalp hair be inaccessible, an equivalent quantity of body hair can be used. By head hair, we specifically mean scalp hair. Body hair refers to any other types of hair (facial, axillary, etc.).
Process Overview
The laboratory processing of drug test results comprises four principal stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a lab's system. This includes ensuring the sample was correctly sealed and delivered, assigning a random LAN (Laboratory Accessioning Number), and finalizing any extra data input not covered by an electronic chain of custody procedure.
Screening is a preliminary rapid evaluation for substances of abuse. While Screening is an economical method to dismiss drug usage in most samples, a positive outcome necessitates confirmation to be valid in court. All samples that are initially positive in Screening require subsequent confirmation.
Should a sample suggestively test positive during the Screening phase, additional hair is extracted from the initial sample and set for Extraction. In this phase, substances are extracted from hair at much lower levels than in other processes (e.g., urine or oral fluid), making hair drug screening the most challenging technique to execute.
Confirmation of any positive screening outcome is performed using GC/MS, GC/MS/MS or LC/MS/MS. Any samples suspected as positive are cleansed prior to confirmation if required. The entire lab process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards.

The joint meeting of the Society of Hair Testing (SoHT) and the Italian Group of Forensic Toxicologists (GTFI) was organized in Verona, June 8–10, 2022, and hosted by the Legal Medicine team of the Verona University Hospital, directed by Franco Tagliaro together with Federica Bortolotti and Rossella Gottardo.
It served as a prominent platform for knowledge exchange and collaboration, facilitating groundbreaking advancements in hair testing and analysis. In this special issue of Drug Testing and Analysis, we aim to showcase the remarkable manuscripts presented at this significant event, shedding light on the latest research and highlighting the future directions in this field.
Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.
Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis. The impact of hair treatments on the oxidation/decomposition of drugs in hair was also explored, as the long-term fate of drugs incorporated in the keratin matrix. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.
Forensic Applications and Interpretation: One of the vital objectives of hair testing is its application in forensic investigations and legal proceedings. The SoHT meeting in Verona emphasized the significance of rigorous interpretation of analytical results and the need for standardized protocols. Manuscripts in this section present advancements in forensic toxicology, and have explored the challenges posed by emerging designer drugs and strategies to combat their proliferation. The pitfalls encountered when the exogenous/endogenous nature of a substance is questioned were presented and discussed. The special issue presents also manuscripts that delve into the ethical implications of drug testing in drug facilitated sexual assaults.
Clinical Applications of hair testing are witnessed by the insight on environmental tobacco smoke exposure, assessed by hair analysis in a population of students and the study of in utero-exposure to drugs of abuse through neonatal hair analysis. Exposure to drugs was also important in cases of child abuse/neglect, when the clinical purpose of hair testing merge with its forensic applications.
The legal framework surrounding hair testing and the achievement of guidelines to ensure fairness, accuracy, and confidentiality in drug testing practices have also been discussed,and the SoHT consensus on general hair testing and testing for drugs of abuse was presented at the meeting and published as a Letter to the Editor.
In conclusion, the special issue of Drug Testing and Analysis, featuring manuscripts from the SoHT–GTFI meeting in Verona 2022, reflects the remarkable advancements achieved in this field. The manuscripts provide valuable insights into novel analytical techniques, biomarkers, pharmacokinetics, forensic applications, and ethical considerations. As we embrace these advancements, we pave the way for a safer, healthier society, where drug testing and analysis serve as powerful tools in protecting public health and maintaining integrity in various sectors.
