Hair testing has emerged as a significant method for identifying drug and alcohol usage. Hair retains a prolonged history of alcohol and drug consumption by enclosing biomarkers within its strands. When gathered near the scalp, hair can offer up to a 3-month period for detecting alcohol and drugs. It's easy to collect, challenging to tamper with, and convenient to transport.
A 1.5-inch section consisting of around 200 hair strands, comparable in size to a #2 pencil and situated nearest to the scalp, yields 100mg of hair, which is the optimal sample for both screening and confirmation. For EtG, additional panels, or tests exceeding 10 panels, 150mg of the specimen is advised. Utilizing a jeweler’s scale is recommended for weighing the specimen. If scalp hair is unobtainable, an equivalent portion of body hair may be used. References to head hair specifically mean scalp hair. Body hair encompasses all other types (such as facial or axillary).
Process Overview
The laboratory processing of drug test results encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial integration of a sample into the laboratory system. Tasks include verifying the sample's proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any necessary data entry that an electronic chain of custody system hasn't provided.
Screening entails a preliminary, swift check for drugs of abuse. This cost-efficient method is effective for ruling out drug use in most samples, but any positive screening result must be validated for court acceptance. Samples that test presumptive positive in Screening require further confirmation.
If a sample tests presumptive positive during the Screening phase, additional hair is extracted from the initial specimen for the Extraction process. Here, drugs are extracted from hair at notably lower concentrations compared to other methods (such as urine or oral fluid), underscoring the complexity of hair drug screening.
Positive screening confirmations are performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples are properly cleansed before confirmation as necessary. The entire laboratory workflow, from Accessioning to Confirmation, is overseen under CAP (College of American Pathologists) Hair designation and adheres to ISO/IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: These tests are frequently mistaken as "hair follicle tests", yet they analyze the hair strand rather than the follicle beneath the scalp.

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.
