Hair analysis is now a recognized method for identifying drug and alcohol usage. Hair strands can capture markers within their fibers, offering a chronicled view of substance use. When obtained near the scalp, hair can reveal drug and alcohol consumption over a span of around 90 days. Hair collection is straightforward, relatively tamper-proof, and easily transportable.
A 1.5-inch segment comprising roughly 200 hair strands (approximately the girth of a #2 pencil) near the scalp provides 100mg of hair, which constitutes the perfect amount for both screening and verification. For EtG, supplementary tests, or panels beyond 10, a 150mg sample is suggested. It's advisable to weigh the hair using a jeweler's scale. If scalp hair isn't an option, a similar volume of body hair can be used. The term 'head hair' specifically refers to scalp hair alone, whereas 'body hair' encompasses all other types (such as facial, axillary, etc.).
Process Overview
The process for laboratory drug testing encompasses four vital stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary integration of a sample into the laboratory workflow. This procedure includes confirming that the sample is sealed and dispatched correctly, assigning a unique LAN (Laboratory Accessioning Number), and entering any further data not captured by an electronic chain of custody.
Screening consists of an initial rapid assessment for illicit substances. Although this method is cost-effective for negating drug presence in most samples, any positive findings must be validated to be legally recognized. Samples testing positive at this stage necessitate subsequent confirmation.
In cases where the Screening result is presumptively positive, additional hair is retrieved from the initial sample and readied for Extraction. This phase involves extracting drugs from hair at substantially lower concentrations than other methods (such as urine or saliva), rendering hair drug analysis one of the most challenging techniques to execute.
Confirmation of a positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicating presumptive positivity are cleansed prior to confirmation if necessary. The full laboratory sequence, from Accessioning to Confirmation, is guided by the CAP (College of American Pathologists) Hair criteria and compliance with ISO/IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Commonly labeled as "hair follicle tests," the analysis actually examines the hair strand, excluding 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. 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.
