From a forensic toxicology point of view, human hair samples are extremely well suited for determining a person’s consumption pattern of medication or drugs of abuse over a period of time.

A human hair grows between 0.25 and 0.4 millimetres per day, which equates to 7.5 and 12 millimetres per month.

Once consumed, drugs active ingredients from medications as well as the metabolites formed, are distributed throughout the body and also incorporated into human hair as it grows.

Please read this great article, where you can see how the Institute of Forensic Medicine and GERSTEL have successfully automated the manual method  previously used at the Institute.
