Recently, hair follicle drug testing has become a more prevalent method for substance screening. Employers, legal systems, and Substance Abuse professionals often favor hair tests over urine tests. Hair tests are the preferred choice for zero-tolerance policies, judicial use, and probation purposes. The main advantage of hair testing is its longer detection window, up to 90 days, coupled with secure collection that makes tampering difficult. For recent drug use, within 5 days, urine tests still provide the best accuracy.

Hair analysis is considered an effective method for identifying drug and alcohol consumption. Hair retains a long-term record of drug and alcohol intake by embedding biomarkers within the fibers of the hair shaft as it grows. When taken near the scalp, hair offers around a 3-month window for detecting alcohol and drug use. It is easy to collect hair, challenging to tamper with, and straightforward to mail.
A sample measuring 1.5 inches, consisting of about 200 hair strands (roughly the thickness of a #2 pencil) near the scalp, will yield 100mg of hair, the preferred amount for testing and verification. For tests such as EtG, add-ons, or tests exceeding 10 panels, it’s suggested to use 150mg of hair. It's advisable to weigh the sample using a jeweler's scale. Should scalp hair be inaccessible, an equivalent portion of body hair can be taken. In discussing head hair, only scalp hair is meant. The term body hair pertains to other types such as facial, axillary, etc.
Process Overview
The laboratory processing of a drug screening result includes four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a lab’s system. This step involves checking that the sample was properly sealed and dispatched, giving it a unique LAN (Laboratory Accessioning Number), and filling in any additional information not provided electronically.
Screening is a preliminary rapid test for the presence of drugs of abuse. Though Screening is a cost-effective means to eliminate drug use for most samples, a positive screen must be validated for it to be court-admissible. Samples that test presumptively positive in Screening necessitate subsequent confirmation.
If a sample shows presumptive positivity during Screening, more hair is extracted from the original sample and readied for Extraction. This involves extracting drugs from hair at significantly lower concentrations than those found in other methods (like urine or oral fluid), making hair drug screening the most complex method to execute.
Confirmation of any positive results from the screening is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples showing presumptive positivity undergo washing prior to confirmation as deemed necessary. The complete laboratory procedure from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair guidelines and accreditation standards of ISO / IEC 17025.

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.
