Hair testing is now recognized as a robust mechanism for detecting drug and alcohol consumption. Hair retains a historical record of substances by embedding biomarkers within the strands as they grow. When sourced near the scalp, hair offers an approximate detection window of three months for alcohol and drugs. Hair is straightforward to collect, challenging to tamper with, and simple to send for testing.
A sample measuring 1.5 inches, comprising roughly 200 hair strands (equivalent to the thickness of a #2 pencil) closest to the scalp, yields about 100mg of hair, which is the optimal amount for both screening and confirmation. For EtG, additional tests, and/or analyses exceeding 10 panels, a specimen weighing 150mg is advisable. Utilizing a jeweler's scale is recommended for weighing the sample. If scalp hair is not available, a similar quantity of body hair can be used. The term head hair specifically refers to scalp hair, whereas body hair denotes all other types, including facial and axillary hair.
Process Overview
The laboratory analysis of a drug test result involves four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a lab's system. This process includes confirming the sample's proper sealing and shipping, assigning a Laboratory Accessioning Number (LAN) randomly, and completing any additional data input not included by an electronic chain of custody system.
Screening represents an initial rapid assessment for drugs of abuse. While Screening effectively eliminates drug usage in most samples at a lower cost, any positives must be verified to be valid in legal contexts. Presumptive positives from Screening require secondary validation.
When a sample is presumptively positive during the Screening phase, additional hair is drawn from the original specimen for Extraction preparation. In this phase, drugs are retrieved from hair at much lower concentrations compared to methods like urine or oral fluid testing, making hair drug screening exceptionally challenging.
Confirmation of any positive outcomes from Screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive specimens are washed for Confirmation as necessary. The complete lab procedure from Accessioning to Confirmation undergoes scrutiny under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:

Note: Although often termed "hair follicle tests," the test evaluates the hair strand, not 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. The manuscripts provide valuable insights into novel analytical techniques, biomarkers, pharmacokinetics, forensic applications, and ethical considerations.
