Drug Testing to Detect Illicit Drug Misuse

It is generally accepted that, for an average person, head hair grows at a rate of approximately one cm per month. If an individual consumes a drug, then during its circulation in the bloodstream, a proportion of the drug and its metabolites will enter the hair follicle via the dermal papilla and become incorporated into the growth of the hair shaft.

To drug test the hair, the sample is measured and cut into segments according to the requirements of the case. Each segment is analysed separately for the presence of drugs and their metabolites. Combined with an estimate of the growth rate of the hair, this assists in the determination of  drug use for an individual.

The Benefits of Hair Drug Testing for court matters

Did you know that if you request an ‘overview’ drugs of abuse test to cover a period of three months, even if your client has abused drugs occasionally, the test may show positive for the whole three month period? This can give the impression that the sample donor had been abusing drugs for the whole period analysed.

To overcome this, we recommend a three month segmented legal hair drug testing is undertaken. As an example, the sample donor could show positive for one month and negative for the other two months. Therefore a more accurate reflection of the sample donor’s drug abuse/abstinence can be presented to the court.

For example, a six-month analysis requesting two segments would equate to an analysis of two three-month segments.
See the table below for example of hair analyses regularly performed at our laboratory:

Analysis Type Required (Months) Number of Segments Reported Time Period
3 1 Three Months
3 3 Three Individual Months
6 2 Two x Three Month Periods
6 6 Six Individual Months

Hair drug testing gives a detailed history of drug use from one week after ingestion, up to approximately a twelve month period. Drug testing can detect in urine soon after ingestion and for several days thereafter. Drugs can be detected in oral fluid shortly after being consumed and for up to forty eight hours.
