Hair analysis has emerged as a strong method for identifying the use of drugs and alcohol. Hair records a comprehensive timeline of substance use by embedding biomarkers within its developing strands. When taken from near the scalp, hair can provide an approximate 3-month period of substance detection for both alcohol and drugs. It is straightforward to gather, somewhat challenging to tamper with, and convenient for transportation.
A sample measuring 1.5 inches with roughly 200 hair strands (akin to a #2 pencil size) next to the scalp yields 100mg of hair, which is ideal for analysis and corroboration. For tests including EtG or exceeding 10 panels, it's advised to obtain 150mg of the specimen. Using a jeweler’s scale to measure the specimen is suggested. If head hair isn't available, a similar quantity of body hair can be utilized. Mention of head hair pertains specifically to scalp hair. Body hair encompasses all other hair types (such as facial, axillary, etc.).
Process Overview
There are four key steps in processing a laboratory drug test result: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the preliminary steps of integrating a sample into a lab system, ensuring that it was correctly sealed and transported, assigning it a LAN (Laboratory Accessioning Number), and completing any lacking information not included by an electronic custody chain.
Screening executes an initial quick evaluation for drugs. It serves as an economical approach to exclude drug presence in most samples, but a positive screen must undergo confirmation for legal proceedings. Presumptive positives identified during Screening necessitate secondary confirmation.
When a sample tests presumptively positive during Screening, further hair is extracted from the original sample for Extraction. Here, substances are isolated from hair at much reduced levels relative to other techniques, like urine or oral fluid, thus making hair drug analysis one of the hardest techniques to execute.
Confirmation of any positive screening is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All samples marked as presumptively positive are cleansed prior to confirmation if required. Both the entire lab procedure from Accessioning to Confirmation is done under the CAP (College of American Pathologists) Hair certification and the accreditation to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although referred to as "hair follicle tests", the test actually assesses the hair shaft 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.
