Hair testing is recognized as an effective method for identifying drug and alcohol use. Hair archives a comprehensive history of alcohol and other substances by embedding biomarkers within the fibers of the growing hair strand. When taken close to the scalp, hair can offer a detection window spanning nearly 3 months for both alcohol and other substances. Collecting hair is straightforward, relatively resistant to tampering, and easy to transport.
A 1.5-inch segment comprising about 200 strands of hair (equivalent to the thickness of a #2 pencil) near the scalp offers 100mg of hair, serving as the optimal sample for both screening and confirmation tests. For EtG tests, add-ons, or for tests exceeding 10 panels, 150mg of the specimen is advisable. We suggest using a jeweler’s scale to weigh the specimen. If scalp hair is not accessible, a comparable amount of body hair can be used. References to head hair pertain specifically to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result consists of four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial integration of a specimen into a laboratory’s system. This step entails verifying the sample’s seal and proper shipment, issuing a random LAN (Laboratory Accessioning Number), and completing any further data entry lacking from an electronic chain of custody system.
Screening is a preliminary rapid analysis for substances of abuse. While Screening is a cost-efficient strategy to negate drug use in most specimens, a positive screen requires confirmation to stand in a legal setting. Any specimens that are preliminarily positive in Screening necessitate additional confirmation.
Should a sample test presumptively positive during Screening, further hair is extracted from the original specimen and prepared for Extraction. During this stage, substances are retrieved from hair at significantly lower concentrations compared to other techniques (e.g., urine or oral fluid), establishing hair drug screening as the most challenging procedure to execute.
Confirmation of any positive Screening outcome is conducted via GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples are cleaned as necessary. The complete laboratory procedure from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair certification as well as the accreditation to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although commonly termed "hair follicle tests", the examination analyzes 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. 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.
