Another unique advantage of hair analysis is that it not only can detect if drugs of abuse have been used, but in-depth testing can also provide information on the quantity and historic pattern of individual drug use.
ASTOUNDING RESULTS FROM AN ANALYSIS OF 90,000 PAIRED HAIR AND URINE RESULTS J.B. Hunt Transport Services is one of the largest transportation logistics companies in North America, and as a motor carrier, must conduct urinalysis drug tests in accordance with DOT regulations. However, a series of events led the company to believe that urinalysis alone was not working, including two unfortunate crashes where J.B. Hunt drivers were involved in accidents that claimed three lives. Both drivers had clean records, but both tested positive at the scene for cocaine. All required urinalysis tests had been conducted and it was concluded that these drivers were likely substituting their urine samples. Tese incidents caused J.B. Hunt to
look into more stringent safety measures, and hair testing was one of the options
28 datia focus
they explored. With hair testing, users cannot “beat the system” by abstaining from drug use in the days leading up to the test, or take evasive action by adulterating or tampering with the test. Despite the extra costs, a decision
was made to begin hair testing. Since implementing the hair testing drug program, J.B. Hunt has consistently lowered the positive rate of drug users from year to year, and has significantly lowered the number of accidents occurring on the job, making J.B. Hunt a much safer place to work. • Pre-employment positives on the hair tests started out near 15% and then dropped quickly aſter the hair testing program was implemented.
• Te DOT Random Urine positive rate began to drop rapidly as drug users were removed from the fleet. Once hair testing was implemented the DOT random urine positive rate declined 79%.
• As this program continued and it became clear that job applicant and current employee drug use would be detected, the overall quality of hire increased.
• When it comes to the hiring of drivers and promoting a culture of safety, J.B. Hunt is hailed as an industry leader, including being selected for the 2014 “Company of the Year on Workplace Substance-Abuse Prevention” award.
UNDERSTANDING THE SCIENCE OF HAIR TESTING Hair testing is already a well established workplace tool offering benefits such as a simplified (observed) collection process and elimination of transportation constraints. Hair samples, which are not a bio-hazard, can be shipped from anywhere in the world without the risk of deteriorating during transit. Hair stores drugs and their metabolites permanently, and is not influenced by the normal hazards of transportation that affect urine, saliva and blood. Another unique advantage of hair analysis
is that it not only can detect if drugs of abuse have been used, but in-depth testing can also provide information on the quantity and historic patern of individual drug use. When proper wash protocols are followed by the laboratory, environmental contamination is not an issue, as proven by independently validated sources like the FBI.7
Proper testing methods that
remove any melanin content also eliminate any concern with hair-color bias; various landmark reports and peer-reviewed scientific papers have demonstrated the lack of any hair-color bias.8
in the process of establishing the technical and scientific guidelines for hair testing,
94,715 Paired Hair and DOT Urine Tests on the Same Individuals
May 2006 to December 2015 (Positive includes refusal to test) Urine Positive
714 Positive Rate 0.75%
Psychemedics Hair Positive
Positive Rate 4,842 5.12%
J.B. Hunt conducted its own paired hair and urine analysis. From May 2006 to December 2015, the company performed a comparison of 94,715 paired hair and DOT urine tests on the same individuals. The results were astounding, with 4,842 (5.12%) testing positive with Psychemedics hair tests, but only 714 (0.75%) testing positive with urinalysis.
