Recently, hair follicle drug tests have become a preferred method for screening. Many employers, judicial systems, and Substance Abuse professionals lean towards hair testing over urine tests. The main advantage of these tests lies in their lengthy detection window, which provides up to 90 days of drug use history, is collected under supervision, and offers almost no room for cheating. However, for detecting recent drug use within 5 days, urine tests remain the most accurate.

Hair analysis has emerged as an effective mechanism for identifying drug and alcohol consumption. Hair retains a prolonged record of alcohol and drugs by embedding biomarkers inside the fibers of the growing hair. When taken near the scalp, hair can offer up to a 3-month detection timeframe for alcohol and drugs. It is straightforward to gather, relatively hard to tamper with, and simple to transport.
A 1.5-inch segment of roughly 200 hairs (approximately the size of a #2 pencil) nearest to the scalp yields 100mg of hair, the ideal quantity for testing and validation. For EtG, additional tests, and/or panels exceeding 10, a 150mg sample is advised. We suggest measuring the sample with a jeweler’s scale. If scalp hair is unavailable, an equivalent quantity of body hair may be used. By head hair, we exclusively mean scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Summary
The four primary phases in the laboratory processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the preliminary processing of a sample into a lab’s system. This encompasses ensuring the sample was properly sealed and shipped, assigning a randomized LAN (Laboratory Accessioning Number), and completing any extra data entry not supplied by an electronic custody system.
Screening entails an initial cursory check for substances of abuse. While Screening is cost-effective for eliminating drug usage in most samples, a positive screen needs confirmation for it to be court-admissible. Samples that test presumptively positive during Screening require secondary confirmation.
If a sample tests presumptively positive during Screening, additional hair is drawn from the initial sample and readied for Extraction. During this step, drugs are extracted from hair at much lower concentrations compared to other methods (such as urine or oral fluid), which explains why hair drug analysis is among the most challenging methods to conduct.
Confirmation of any positive screening finds is done through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation if necessary. The complete laboratory process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair classification and the accreditation to ISO / IEC 17025 standards.

Drawbacks:
Note: Commonly known as "hair follicle tests", these tests actually examine the hair strand, not the follicle beneath the scalp

With its multidisciplinary nature, hair testing brings together researchers, scientists, and experts from various domains to develop innovative techniques, explore new methodologies, and address emerging concerns, responding to the ever-evolving challenges of drug abuse, therapeutic drug monitoring, and environmental exposures to pollutants.
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.
