Hair analysis has gained recognition as a robust method for identifying drug and alcohol consumption. Hair captures a prolonged record of substances by embedding biomarkers in the strands of hair as it grows. Collected near the scalp, hair can show drug and alcohol use for up to a three-month period. This method is easy to gather, hard to tamper with, and straightforward to send for analysis.
A sample length of 1.5 inches comprising about 200 hair strands (approximately the diameter of a #2 pencil) taken near the scalp yields 100mg of hair, which suffices for screening and confirmation. For more extensive testing, including EtG and tests exceeding 10 panels, 150mg is optimal. It's advised to measure the specimen using a jeweler’s scale. If scalp hair is missing, an equal portion of body hair is acceptable. When discussing head hair, it indicates scalp hair specifically, while body hair includes all other types (e.g., facial, axillary).
Process Overview
Key stages in lab processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning starts with the sample's entry into the lab system. This step ensures the sample’s seal and shipment were intact, assigns it a random LAN (Laboratory Accessioning Number), and records any extra information not captured electronically via chain of custody.
Screening provides a preliminary assessment for drugs. Despite being cost-efficient in excluding drug use across most samples, a positive screen necessitates further confirmation for legal validity. Samples that test positive during Screening must undergo additional confirmation.
If Screening indicates a presumptive positive, additional hair is extracted from the original batch and readied for Extraction. In Extraction, drugs are drawn from hair at lower concentrations compared to methods like urine testing, highlighting hair screening’s complexity.
Positive screening confirmations employ GC/MS, GC/MS/MS, or LC/MS/MS. All samples showing presumptive positives are cleaned before confirmation as required. The whole lab process from Accessioning to Confirmation observes both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.
Advantages of hair drug testing:
Limitations:
Note: Though often named "hair follicle tests", the procedure examines the hair strands, 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. 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.
