Lately, hair follicle drug tests have become more widespread as a method for drug detection. Employers, legal authorities, and Substance Abuse experts often prefer hair tests over traditional urine tests. These tests are ideal for organizations with strict anti-drug policies, judicial settings, and with probation. The key advantage of hair testing is its extended detection timeframe—up to 90 days—with strict observation during collection, greatly minimizing cheating risks. However, urine tests remain more precise for recent consumption within the last 5 days.

Hair testing has gained recognition as an effective method for identifying drug and alcohol consumption. By encapsulating biomarkers within the strands of hair, it offers a comprehensive history of alcohol and drug use. When taken from just above the scalp, hair can reveal evidence of drug and alcohol use for a timespan of up to three months. The collection process for hair is straightforward, difficult to tamper with, and convenient to transport.
A hair sample of 1.5 inches, consisting of around 200 strands (comparable to the thickness of a #2 pencil), proximal to the scalp, will yield approximately 100mg of hair—a suitable amount for both screening and validation. For EtG, additional testing, or tests exceeding 10 panels, a sample size of 150mg is preferred. It is advisable to weigh the sample using a jeweler’s scale. Should scalp hair be inaccessible, a comparable quantity of body hair can be utilized. "Head hair" refers specifically to scalp hair, whereas "body hair" encompasses all other types (including facial and axillary hair).
Process Overview
The laboratory processing of a drug test result encompasses four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial integration of a sample into a lab’s system, which involves checking that the sample is properly sealed and sent, allocating a randomized LAN (Laboratory Accessioning Number), and finalizing any data input missing from an electronic chain of custody system.
Screening is an initial evaluation for substances of abuse. Although it provides a budget-friendly method to exclude drug use in most samples, confirmed results are necessary for legal admissibility. Samples deemed presumptively positive in the Screening phase require additional validation.
If screening implies positivity, further hair is harvested from the original sample for Extraction. At this juncture, drugs are isolated from hair at significantly lower concentrations than in different testing methods (such as urine or oral fluid), making hair drug screening one of the most challenging techniques.
To verify any positive results from Screening, GC/MS, GC/MS/MS, or LC/MS/MS methods are employed. Presumptively positive samples are cleansed as necessary before Confirmation. The lab process, covering Accessioning to Confirmation, undergoes scrutiny based on 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.
