Hair testing is now regarded as a significant method for detecting drug and alcohol consumption. Hair can capture a long-term record of alcohol and other drugs by embedding biomarkers in the strands of growing hair. When taken near the scalp, hair offers a detection period of up to 3 months for alcohol and other drugs. Hair collection is straightforward, relatively tamper-resistant, and convenient to transport.
A hair sample of 1.5 inches, consisting of about 200 strands or the size of a #2 pencil, near the scalp yields 100mg of hair, which is ideal for both screening and confirmation. For EtG, additional tests, or tests exceeding 10 panels, a specimen of 150mg is suggested. It’s advisable to weigh the specimen using a jeweler’s scale. If scalp hair is not accessible, an equivalent amount of body hair can be used. When we mention head hair, it strictly refers to scalp hair, whereas body hair includes all other hair types (facial, axillary, etc.).
Process Overview
The laboratory process for a drug test result involves four main steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial sample processing into a lab system, ensuring the sample was sealed and transported correctly, assigning a random LAN (Laboratory Accessioning Number), and completing supplemental data entry missing from an electronic chain of custody system.
Screening provides a preliminary rapid assessment for drugs of abuse. While Screening is an economical method to initially rule out drug use in most samples, any positive result must be confirmed for legal admissibility. Samples testing presumptive positive in Screening need further confirmation.
If Screening indicates a presumptive positive, more hair is extracted from the initial sample for Extraction. In this phase, drugs are isolated from hair at a lower concentration compared to other methods (e.g., urine or oral fluid), which makes hair drug testing one of the most challenging methodologies.
Positive Screening results go through Confirmation using technologies like GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive specimens are cleansed before confirmation if required. The full lab procedure from Accessioning to Confirmation is under scrutiny by both the CAP (College of American Pathologists) Hair standards and the accreditation 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.
