Hair testing has emerged as an effective instrument for detecting drug and alcohol consumption. Hair captures a prolonged history of substance use by embedding biomarkers within the fibers of the developing hair strand. When sourced near the scalp, hair can offer approximately a 3-month detection timeframe for alcohol and other substances. Its simplicity in collection, resistance to tampering, and ease of shipment make it advantageous.
Acquiring a 1.5-inch segment of nearly 200 hair strands (comparable to a #2 pencil) closest to the scalp yields 100mg of hair, ideal for screening and confirmation. For EtG, add-ons, or tests exceeding 10 panels, 150mg is advised. We suggest weighing the sample on a jeweler’s scale. In the absence of scalp hair, a similar quantity of body hair can be taken. When mentioning head hair, we imply scalp hair exclusively. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The procedure for processing a drug test result in a laboratory includes four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning comprises the initial handling of a sample into the laboratory’s framework. This stage involves ensuring the sample was sealed and dispatched correctly, assigning an arbitrary LAN (Laboratory Accessioning Number), and executing any additional data entry absent from an electronic chain of custody system.
Screening represents an initial rapid assessment for drug abuse. While Screening is an economical method to eliminate drug use in most samples, a positive result must be validated for legal acceptance. Samples presumptively positive during Screening require further confirmation.
Should a sample be presumptively positive at the Screening phase, more hair is extracted from the original sample for preparation in Extraction. Here, drugs are extracted from hair at substantially lower concentrations than other approaches (e.g., urine or oral fluid), rendering hair drug screening particularly challenging to execute.
Confirmation of any positive screening outcome is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo a wash before confirmation if necessary. The comprehensive laboratory process from Accessioning to Confirmation undergoes a review under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Commonly termed as "hair follicle tests", the focus is on the hair strand rather than the subscalp hair follicle.

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.
