Hair analysis is regarded as an effective method for identifying the use of drugs and alcohol. Hair captures a prolonged record of substances by embedding biomarkers within the strands as they grow. When taken from near the scalp, hair can provide insights into drug and alcohol usage over a period of roughly three months. Hair samples are easy to gather, relatively tamper-resistant, and simple to transport.
A hair sample measuring 1.5 inches, consisting of about 200 strands (approximately the thickness of a #2 pencil) and cut closest to the scalp, yields 100mg of hair, which is optimal for both screening and verification. For EtG, extra tests, or when requiring more than 10 panels, a sample of 150mg is preferable. We suggest using a jeweler’s scale for accuracy. In cases where scalp hair is not accessible, an equivalent amount of body hair is suitable. By head hair, we mean scalp hair exclusively, while body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The process in the lab for processing a drug testing result involves four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the sample’s initial setup within the laboratory’s framework. This involves making sure the sample is securely sealed and sent correctly, assigning a unique LAN (Laboratory Accessioning Number), and filling in any required data not already provided by an electronic custody system.
Screening is a preliminary evaluation for illicit substances. While Screening efficiently rules out drug use for most samples, a positive outcome must be verified for legal acceptability. Samples flagged as potentially positive in Screening need further confirmation.
When a sample shows potential in the Screening phase, additional hair is extracted from the initial sample for Extraction. Here, substances are separated from hair at lower levels compared to other methods (ex. urine or saliva), adding complexity to hair drug testing procedures.
Confirming a positive Screening result employs techniques like GC/MS, GC/MS/MS, or LC/MS/MS. All possibly positive samples undergo cleansing before confirmation as required. The resulting laboratory operation, from Accessioning to Confirmation, is audited by both the CAP (College of American Pathologists) Hair program and the ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Although often called "hair follicle tests", the examination targets 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.
