Emerging trends show an increase in the preference for hair follicle drug tests over traditional methods. Entities such as employers, legal systems, and substance abuse experts mandate these to replace the standard urine test. Hair follicle exams are highly favored for their extensive detection windows, up to 90 days, with observation to prevent tampering. Yet, for recent use, urinary tests remain unmatched in accuracy over the initial five days.

Hair testing is now regarded as an effective method for identifying drug and alcohol usage. Hair captures a lengthy record of alcohol and other drugs by securing biomarkers within the fibers of the hair as it grows. When gathered near the scalp, hair can reveal alcohol and other drugs up to a roughly 3-month detection period. Hair is straightforward to gather, somewhat resistant to tampering, and simple to transport.
A 1.5-inch sample comprising around 200 strands of hair (similar to the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the ideal quantity for analyzing and confirming. For EtG, additional tests, and/or tests exceeding 10 panels, 150mg of the sample is advised. We suggest measuring the sample's weight with a jeweler’s scale. If scalp hair is not present, a comparable amount of body hair can be obtained. When mentioning head hair, we specifically mean scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The key phases in the laboratory processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial handling of a sample upon its entry into a laboratory’s system. This step encompasses verifying the sample's seal and proper shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any remaining data entry absent from an electronic chain of custody system.
Screening conducts an initial rapid test for drugs of abuse. While Screening offers a budget-friendly method to negate drug use in most samples, a positive screen necessitates confirmation for courtroom admissibility. All samples deemed presumptively positive during Screening mandate a secondary confirmation.
If a sample is found presumptively positive during the Screening phase, additional hair is sourced from the original sample and prepped for Extraction. In this phase, drugs are retrieved from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), thus making hair drug screening the most intricate technique to execute.
Confirmation of any positive screening outcome is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation when required. The entire lab procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the accreditation pursuant to 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. 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.
