Hair analysis is increasingly recognized as an effective means for identifying drug and alcohol consumption. Hair retains a chronicled record of alcohol and substance markers by embedding them in the hair fiber as it grows. When collected near the scalp, the hair can reveal drug and alcohol use for a period of up to three months. Collecting hair is straightforward, not easily altered, and convenient to transport.
A sample measuring 1.5 inches in length, consisting of around 200 strands (approximately the diameter of a #2 pencil) from closest to the scalp, yields 100mg of hair—ideal for testing. For EtG enhancements and/or testing beyond 10 panels, 150mg of the sample is advised. We suggest using a jeweler’s scale to weigh the sample. If scalp hair is inaccessible, an equivalent mass of body hair can be taken. Head hair denotes only scalp hair, whereas body hair implies any other hair type (facial, armpit, etc.).
Process Overview
In laboratory processing of drug tests, the four primary steps are Accessioning, Screening, Extraction, and Confirmation.
Accessioning incorporates entering a sample into a lab's system initially. This consists of confirming the sample was sealed and transported correctly, allocating a unique LAN (Laboratory Accessioning Number), and performing any supplementary data input absent from an electronic chain of custody system.
Screening is a preliminary rapid assessment for the presence of drugs. Although Screening efficiently eliminates drug use from most samples, a favorable result requires confirmation to stand in legal scenarios. All samples indicating potential positive results through Screening necessitate additional confirmation.
If Screening yields a possibly positive outcome, additional hair is drawn from the original sample for Extraction. At this phase, drug substances are separated from hair in considerably lower concentrations relative to methodologies like urine or oral fluid testing, rendering hair drug screening as a complex methodology to execute.
Verification of positive Screening results is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Washes are performed on all suspected samples before confirmation if needed. The entire lab procedure from Accessioning to Confirmation is scrutinized under the guidelines of both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: While habitually termed "hair follicle tests", the test analyzes the hair strand itself, not 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.
