In recent developments, hair follicle drug testing is gaining preference. Many firms, judicial systems, and addiction specialists opt for this method over traditional urine tests. Suitable for zero-tolerance workspaces, courts, and individuals under supervision, a key advantage is the extended 90-day detection window, challenging to evade. For recent usage, however, urine testing remains the most precise choice.

The use of hair testing has evolved into a potent method for identifying drug and alcohol consumption. Hair offers a comprehensive overview of alcohol and drug use by embedding biomarkers within its growing strands. When gathered near the scalp, hair can extend the detection window to around three months for both alcohol and drugs. The collection process is straightforward, tampering with hair samples is challenging, and they are easy to transport.
Harvesting a 1.5-inch section of roughly 200 hairs (similar in size to a #2 pencil) nearest to the scalp yields 100mg of hair, which is optimal for screening and verification. For EtG, additional tests, or tests covering more than 10 panels, a 150mg sample is advisable. It's suggested to weigh the sample using a jeweler’s scale. Should scalp hair be unavailable, collecting an equivalent amount of body hair is an option. References to head hair refer solely to scalp hair, while 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.
The Accessioning stage involves the sample's initial integration into the laboratory’s system. This process includes ensuring the sample was properly sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and performing any other necessary data entry not already covered by an electronic chain of custody system.
Screening is a preliminary quick scan for substance misuse. Although Screening is a budget-friendly approach to eliminate drug usage for the majority of samples, a positive screen needs verification before it can be considered admissible in court. Samples that test presumptive positive at the Screening phase require subsequent confirmation.
When a sample tests presumptive positive during the Screening phase, additional hair is extracted from the original sample and prepared for the Extraction stage. Here, drugs are isolated from the hair at lower concentrations compared to other methods (e.g., urine or oral fluid), underscoring why hair drug screening is recognized as a challenging methodology.
Verification of any positive results from screening happens through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are washed as required before confirmation. The complete process, from Accessioning to Confirmation, undergoes evaluation under the CAP (College of American Pathologists) Hair designation as well as the accreditation to ISO / IEC 17025 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. 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.
