Recently, the approach to drug testing has increasingly included hair follicle tests. Many employers, court systems, and substance abuse specialists prefer a hair test over the traditional urine test. Hair follicle drug tests are particularly favored by employers with zero-tolerance policies, courts, and probation programs. These tests offer an extended detection period of up to 90 days, making them nearly impossible to cheat, although urine tests remain the most effective for detecting recent drug use within the last 5 days.

Hair examination is recognized as an efficient approach for identifying drug and alcohol consumption. It offers an extensive record of alcohol and drug use by trapping identifiers in the structure of the developing hair. Hair collected near the scalp can indicate drug and alcohol usage for up to three months. The collection is straightforward, tampering is relatively challenging, and the samples are easy to send.
A haircut sample of approximately 1.5 inches, involving around 200 hair strands (comparable to the girth of a #2 pencil), taken close to the scalp can provide 100mg, the preferred amount for preliminary and confirming tests. For EtG, additions, and/or tests exceeding 10 panels, 150mg is advisable. Utilizing a jeweler’s scale for specimen weighing is suggested. If no scalp hair is present, an equivalent mass of body hair can be gathered. By head hair, we indicate solely scalp hair. Body hair signifies any other hair (such as facial, underarm, etc.).
Process Overview
The lab analysis of a drug testing sample comprises four key phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first phase where a sample is logged into the lab's system, ensuring that it was properly sealed and delivered, assigning a random LAN (Laboratory Accessioning Number), and finishing any lacking data entry from the electronic chain of custody system.
Screening, a primary evaluation for drugs, is a cost-effective means to exclude drug presence. However, to be used legally, any positive outcome from the Screening must undergo Confirmation. Any samples indicating potential positivity in Screening require additional confirmation.
In cases where Screening suggests a positive result, additional hair is extracted from the initial sample for the Extraction phase. This phase separates drugs from hair at a lower concentration compared to other methods (e.g., urine or saliva), rendering hair drug testing the most complex method.
Confirmation of positive Screening outcomes is executed with GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicating probable positivity are cleansed before confirmation, if necessary. The whole lab process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair categorization along with ISO / IEC 17025 standard accreditation.

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.
