Hair follicle drug tests have increasingly become a preferred method in recent years for many employers, courts, and substance abuse professionals. Instead of using traditional urine tests, these stakeholders now often require a hair drug test. Employers with zero-tolerance policies, probation departments, and courts favor them due to their extended detection period of up to 90 days. These tests are collected under observation, making them extremely difficult to manipulate, though urine tests remain more accurate for identifying recent drug use.

Hair evaluations have gained recognition as an influential method for identifying drug and alcohol intake. Hair offers a prolonged record of substances by capturing markers within the fibers of the emerging hair strand. When procured near the scalp, hair can present up to roughly a three-month detection period for alcohol and drugs. Hair collection is straightforward, relatively tamper-resistant, and convenient to transport.
A sample measuring 1.5 inches consisting of around 200 hair strands (about the thickness of a #2 pencil) closest to the scalp yields 100mg of hair, a prime quantity for both screening and confirmation. For EtG, additional analyses, and/or examinations beyond 10 panels, 150mg is suggested. It is advisable to use a jeweler’s scale to weigh the sample. In case scalp hair isn’t available, a comparable amount of body hair could be collected. Reference to head hair implies scalp hair only, while body hair encompasses all other hair types (such as facial or axillary hair).
Process Overview
The process of generating a drug test result in a laboratory entails four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is about initially integrating a sample into the lab's system. This phase includes confirming the sample's proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent in an electronic chain of custody system.
Screening involves a preliminary rapid assessment for drugs of abuse. While cost-effective for excluding drug presence in numerous samples, a positive screening outcome necessitates confirmation for legal acceptance. Samples with presumptive positives in Screening require further verification.
For Screening-stage presumptive positives, additional hair is extracted from the initial sample for the Extraction phase. Here, drugs are isolated from hair at notably lower concentrations than other methods (e.g., urine or oral fluid), making hair drug evaluation the most challenging to execute.
Confirmation of any positive screening is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples undergo washing prior to confirmation as needed. The comprehensive laboratory workflow from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

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.
