Hair follicle drug testing has become increasingly prevalent in recent years. Unlike traditional urine tests, hair tests are favored by employers, courts, and substance abuse professionals enforcing zero-tolerance policies. They offer a longer detection window of up to 90 days and are hard to tamper with. Urine tests, however, are still preferred for detecting recent drug use within a 5-day window.

Hair assessments have emerged as a significant method for identifying drug and alcohol consumption. Hair encapsulates a historical record of alcohol and substance intake by embedding biomarkers within the fibers of the hair as it grows. When collected near the scalp, hair can illustrate a detection timeline extending up to roughly three months for alcohol and drugs. The process of collecting hair is straightforward, hard to tamper with, and convenient to transport.
A specimen of 1.5 inches comprising around 200 strands of hair (comparable to the size of a #2 pencil) close to the scalp yields about 100mg of hair, which is perfect for screening and validation. For EtG tests, supplementary tests, and/or tests over 10 panels, a sample of 150mg is advisable. It's suggested to measure the sample using a jeweler’s scale. Should scalp hair be inaccessible, a comparable quantity of body hair could be gathered. When mentioning head hair, we mean solely scalp hair. Comparatively, body hair includes all other types such as facial and axillary hair.
Process Overview
The pivotal steps in the laboratory analysis of a drug test result involve Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary processing of a sample into the laboratory's framework. This step ensures the sample was correctly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and finalizes any supporting data entry absent in the electronic chain of custody system.
Screening encompasses an initial rapid inspection for drug abuse. Although Screening is an economical tactic to eliminate drug use across numerous samples, a positive result requires confirmation for legal admissibility. Any sample preliminarily positive in Screening mandates additional confirmation.
Should a sample show a potential positive during Screening, more hair is selected from the initial sample for Extraction. This phase involves extracting drugs from hair at considerably lower concentrations than other methods (e.g., urine or oral fluid), making hair drug analysis notably challenging.
Confirmation of any positive result from Screening is performed through GC/MS, GC/MS/MS, or LC/MS/MS. Any suspected positive samples undergo washing before confirmation, as necessary. The entire lab operation from Accessioning to Confirmation is conducted in line with the CAP (College of American Pathologists) Hair criteria and the accreditation to ISO / IEC 17025 standards.

Limitations:
Note: Although commonly called "hair follicle tests", the analysis is conducted on the hair strand, not on the hair follicle beneath the scalp.

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. The research presented in this special issue will undoubtedly shape the future of drug testing and analysis, fostering collaboration and inspiring further innovation in this crucial area of scientific inquiry.
