Hair testing is recognized as a potent method for identifying drug and alcohol consumption. Hair offers a prolonged record of alcohol and drug presence by capturing biomarkers within the strands of growing hair. When taken close to the scalp, hair can reveal up to around a 3-month period for detecting alcohol and drug use. Hair collection is straightforward, challenging to tamper with, and convenient to transport.
A 1.5-inch length of approximately 200 hair strands (around the diameter of a #2 pencil) near the scalp generates 100mg of hair, the preferred quantity for analysis and verification. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of hair is advised. It’s suggested to measure the sample with a jeweler’s scale. If scalp hair cannot be obtained, a comparable amount of body hair is acceptable. Head hair pertains solely to scalp hair, while body hair encompasses all other hair types (facial, axillary, and so forth).
Process Overview
The laboratory processing of a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning constitutes the initial handling of a sample into a laboratory's database. This process entails ensuring that the sample was correctly sealed and dispatched, allocating a unique LAN (Laboratory Accessioning Number), and finalizing any further data input not handled by an electronic chain of custody system.
Screening consists of a preliminary fast evaluation for potential drug abuse. Although Screening is an economical approach to exclude drug usage in the majority of specimens, any positive screen must be verified to be legally valid. Samples that show a presumptive positive in Screening need follow-up confirmation.
Should a sample display a presumptive positive during the Screening phase, additional hair from the initial collection is taken for Extraction. During Extraction, drugs are isolated from hair at a much lower concentration than other methods (e.g., urine or oral fluids), highlighting why hair drug testing is one of the most complex methodologies.
Confirmation of any positive screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo a wash prior to confirmation as needed. The comprehensive laboratory sequence from Accessioning through to Confirmation is evaluated in line with the CAP (College of American Pathologists) Hair recognition and ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Although commonly called "hair follicle tests", the test itself 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.
