Hair Drug Testing

How can hair reveal drug use?

When drugs are consumed, they begin to circulate in the bloodstream, which in turn provides nourishment to the hair strands. Because of this, trace amounts of drug metabolites can be found in hair even as it grows.

How is hair drug testing conducted?Worcester | Hair Drug Testing

In hair drug testing, around 150 strands of hair are collected. If a participant doesn’t have head hair, strands from other part of the body can be collected. When head hair can be used, the 1 1/2 inches of hair closest to the scalp is analyzed.

What is the detection window for hair drug testing?

After 10 days of growth, a hair drug test can detect substances. On average, hair growth is 1/2 inch per month. Thus, drug use can be discovered through hair tests from 10 to 90 days.

What drugs do hair drug tests detect?

The most common hair drug tests are 5-panel, which include marijuana, amphetamines, cocaine, PCP, and opiates. Other options include 5-panel plus expanded opiates that tests for synthetic opiates and the 14-panel which adds prescription drugs.
