How does the hair shaft capture drug use?

Drugs which are ingested circulate in a person’s bloodstream and nourish the developing hair follicle. Trace amounts of the drugs become entrapped in the core of the hair shaft in amounts proportional to the rate of ingestion. These trace amounts of drugs remain in the hair as it grows out from the head at a rate of approximately 1cm per month. Unlike urine, where drug residues can simply be flushed out of the system, drugs are stable in hair for longer periods of time, creating a drug history.

  • A drug or alcohol hair test appointment is 30 minutes and will require identification such as drivers licence or 100 points of identification to proceed
  • For 3-4 months history a hair sample of 3.9cm is required. Samples are generally taken from the head however hair from the beard, chest, back, arms or legs can also be used.
