The use of hair follicle drug tests has surged in recent years. Employers, courts, and substance abuse authorities now favor these over urine tests. For employers with rigorous no-drug policies, and for individuals on probation, these tests are invaluable. They offer a prolonged detection window of up to 90 days, with an observed collection method that is nearly tamper-proof. Yet, for detecting recent drug use within 5 days, urine tests remain superior.

Hair testing is increasingly regarded as an effective method for identifying drug and alcohol use. Hair captures a comprehensive record of substances, trapping biomarkers within the fibers of its growing strands. When collected near the scalp, hair can offer a detection period of up to around three months for drugs and alcohol. Hair is easy to gather, relatively hard to tamper with, and convenient to send.
A 1.5-inch sample comprising approximately 200 hair strands (roughly the diameter of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal sample for both screening and confirmation processes. For EtG, additional analyses, and/or panels exceeding 10 tests, a 150mg specimen is advisable. It's suggested to weigh the sample using a jeweler’s scale. If scalp hair isn't accessible, an equivalent quantity of body hair may be used. When mentioning head hair, it is specifically scalp hair. Body hair includes other types like facial or axillary hair.
Process Overview
The primary steps in the lab processing of a drug test result involve Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the initial stage of processing a sample into a lab’s system. This step ensures the sample was correctly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and concludes any data entry not already available through an electronic chain of custody system.
Screening provides an initial rapid test for drugs of abuse. While Screening is cost-efficient for eliminating drug use in most samples, a positive result must be verified for court acceptance. Samples showing presumptive positives in Screening require secondary confirmation.
If Screening indicates a presumptive positive, additional hair is extracted from the initial sample and prepped for the Extraction stage. Here, drugs are drawn from hair at a significantly lower concentration than other methods (like urine or oral fluid), making hair drug screening the most challenging to execute.
Confirmation of positive results is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives are washed before confirmation when necessary. The entire laboratory workflow, from Accessioning to Confirmation, aligns with both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation 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.
