Hair testing has emerged as an effective means to identify drug and alcohol consumption. Hair strands encapsulate long-term biomarkers within their fibers, offering a detailed history of alcohol and drug use. When sampling close to the scalp, hair can reveal drug and alcohol presence within a time frame of about three months. The collection process is straightforward, the samples are resistant to tampering, and they are easy to transport.
Taking a 1.5-inch sample with approximately 200 hair strands (similar in width to a #2 pencil) nearest the scalp provides 100mg of hair, which is considered ideal for both screening and confirmation processes. For EtG, extended panels, and/or tests exceeding ten panels, a sample of 150mg is advisable. It is suggested to measure the hair on a jeweler’s scale. If scalp hair is inaccessible, an equivalent quantity of body hair can be obtained. References to head hair pertain solely to scalp hair, while body hair encompasses all other types (facial hair, armpits, etc.).
Process Overview
The process of laboratory evaluation for drug tests involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the introduction of a sample into a laboratory’s framework. This step involves checking the sample's proper sealing and shipment, allocating a random LAN (Laboratory Accessioning Number), and completing any missing details not included in an electronic chain of custody system.
Screening offers an initial assessment for drug abuse. While Screening economically eliminates drug use in many cases, a positive result must be confirmed for legal credibility. Samples with presumptive positive findings in Screening warrant a further confirmation test.
In cases where Screening suggests a positive result, additional hair from the initial sample undergoes preparation for Extraction. This stage extracts drugs from hair, presenting a lower concentration than seen in other methods, such as urine or oral fluid, highlighting that hair drug testing is notably challenging.
Confirmation of any positive Screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positives are washed before confirmation if necessary. The entirety of lab processes from Accessioning to Confirmation is audited under the CAP (College of American Pathologists) Hair program as well as ISO / IEC 17025 accreditation standards.

Note: Commonly dubbed as "hair follicle tests," the evaluation actually analyzes the hair strand rather than the follicle beneath the skin.

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.
