Seen as a potent method for recognizing drug and alcohol consumption, hair testing has gained prominence. Hair fibers capture biomarkers, creating a lengthy record of alcohol and other drug usage. When harvested near the scalp, hair offers an approximate 3-month window for detecting alcohol and other drugs. The process of collecting hair is straightforward, relatively tamper-resistant, and convenient for shipping.
By obtaining a 1.5-inch section comprising roughly 200 hair strands (comparable to the diameter of a #2 pencil) near the scalp, 100mg of hair can be acquired, which is the preferred amount for both screening and confirming tests. For tests like EtG or panels exceeding ten, 150mg of the sample is suggested. It's advisable to weigh the sample on a jeweler's scale. If scalp hair lacks availability, an equivalent portion of body hair can be substituted. When mentioning head hair, it specifically refers to scalp hair, whereas body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of drug test results encompasses four critical steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is about the initial integration of a sample within a lab's system. This step validates the sealing and proper shipping of the sample, allocates a random LAN (Laboratory Accessioning Number), and concludes any outstanding data entry not handled by an electronic chain of custody system.
Screening provides a swift preliminary check for drug abuse. Though cost-efficient for excluding drug use in numerous samples, a positive screen must be confirmed for courtroom validity. Samples identified as presumptively positive during Screening require further confirmation.
Should a sample yield a presumptively positive result in Screening, more hair is extracted from the initial batch for the Extraction phase. Here, drugs are isolated from hair at concentrations significantly lower than alternative methods (e.g., urine or oral fluid), emphasizing the complexity of hair drug screening.
Confirmation of positive results from screening employs methods like GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo pre-confirmation washing as necessary. The complete laboratory protocol from Accessioning to Confirmation is scrutinized under both CAP (College of American Pathologists) Hair criteria and 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.
