Hair testing has emerged as a potent method for identifying drug and alcohol consumption. Hair serves as a chronicle of substance use by embedding biomarkers within the fibers of the hair as it grows. Hair samples collected near the scalp can offer a detection range of up to around three months for substances such as drugs and alcohol. The collection process is straightforward; it is relatively resistant to tampering and convenient for transport.
A sample 1.5 inches in length, comprising approximately 200 hair strands (similar in size to a #2 pencil) from the scalp, yields about 100mg—ideal for both screening and confirmation. For EtG tests, add-ons, and tests exceeding 10 panels, a specimen weighing 150mg is preferred. Using a jeweler’s scale is advised for measuring the specimen. In the absence of scalp hair, an equivalent quantity of body hair is acceptable. "Head hair" specifically refers to scalp hair, while "body hair" addresses all other types (face, armpits, etc.).
Process Overview
The laboratory procedure for processing drug test results consists of four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial phase of integrating a sample into a lab's system. This involves ensuring that the sample is appropriately sealed and transported, generating a random LAN (Laboratory Accessioning Number), and filling in any missing data not supplied by an electronic chain of custody system.
Screening provides a preliminary assessment for the presence of drugs. Despite being an economical option to dismiss drug usage in most samples, a positive screening requires confirmation for legal acceptance. Samples yielding a presumptive positive result in Screening necessitate further confirmation.
Should a sample exhibit a presumptive positive outcome during Screening, additional hair is extracted from the original specimen for the Extraction phase. This step involves retrieving drugs from hair at considerably lower concentrations than other methods like urine or oral fluids, making hair drug screening the most challenging technique.
Confirmation of any presumptively positive screening findings is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo washing prior to confirmation if required. The full laboratory process from Accessioning through Confirmation undergoes scrutiny in accordance with both the CAP (College of American Pathologists) Hair specification and accreditation according to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: The term "hair follicle tests" is misleading as the test primarily examines 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. 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.
