Hair testing has emerged as an effective approach for detecting drug and alcohol consumption. Hair offers a comprehensive history of substance use by capturing biomarkers within the strands of growing hair. When taken from close to the scalp, hair can reveal drug and alcohol use within approximately a 3-month period. Hair collection is straightforward, relatively tamper-resistant, and convenient for transport.
A sample of 1.5 inches in length, consisting of about 200 hair strands (roughly the diameter of a #2 pencil) adjacent to the scalp will yield 100mg of hair, which is the preferred quantity for both screening and verification. For EtG, additional tests, or when exceeding 10 panels, 150mg of the sample is suggested. It is advisable to measure the hair specimen using a jeweler’s scale. If scalp hair cannot be obtained, an equivalent volume of body hair can be used. When mentioning head hair, we specifically mean scalp hair. Body hair encompasses all other kinds (facial, axillary, etc.).
Process Overview
The core steps in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial integration of a sample into a laboratory's system. It involves checking that the sample is properly sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional data entry absent from an electronic chain of custody system.
Screening facilitates an initial rapid assessment for substances of abuse. Although Screening is an economical method to eliminate drug usage for most samples, any positive findings must be confirmed for them to be legally viable in court. Hence, samples with presumptive positive results during Screening require a subsequent confirmation.
For samples with presumptive positives during the Screening phase, more hair is extracted from the original sample for the Extraction phase. In this step, drugs are isolated from the hair at concentrations much lower than those in other methods (e.g., urine or saliva), explaining why hair drug testing is among the most complex methodologies.
Confirmation for any positive screening findings is carried out using GC/MS, GC/MS/MS or LC/MS/MS. All samples with presumptive positive results undergo a washing procedure before confirmation if necessary. The entire lab procedure, from Accessioning to Confirmation, is examined under both the CAP (College of American Pathologists) Hair designation and 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.
