Use of Hair for Drug Testing Gaining Momentum with Transportation Companies

If hiring drug-free employees is important to your company, urinalysis can detect recent use, but hair testing can tell you much more.

Hair testing can identify drug use as far back as three months and it is much more difficult to tamper with than urine testing.

This article reveals key findings from a comparative test conducted by J.B. Hunt, a top for-hire motor carrier, a comparative drug testing index by Quest Diagnostics and more.
