While a few
upstarts may be determined to foil drug tests, the giant
drug-testing industry is bent on foiling the foilers. But it
isn't easy.
The industry has created ways to detect adulterant products in
urine samples designed to hide the signs of drug use. It's
starting to use tests based on hair and oral fluid, supposedly
tougher to beat than urine tests. And it's taken its case to
state governments -- several of which recently banned the
marketing and use of drug-test adulterants.
Based on sheer size, the industry should be quashing its
upstart opponents. Sixty-seven percent of major U.S. firms
drug-test employees, according to a 2001 American Management
Association survey, and the industry expects 2003 revenues to
reach an estimated $947 million, according to Market data.
The drug-test foilers, meanwhile, are mostly mom-and-pop-type operations
that sell their wares through Web sites and retail stories.
But the
behemoth drug-testing industry is fragmented. With test
manufacturers, testing labs, consultants, employers and the
government all playing a part, it can be hard to put up a
united front against inventive adversaries willing to try
anything from simple tablets to prosthetic penises that serve
as hidden sacks of somebody else's urine.
Plus, ensuring
that samples aren't tampered can be an expensive proposition,
one that some companies aren't willing to bear.
So far, the
industry's best success seems to be tests that detect common
adulterants, such as bleach, in urine. About half of
Quest Diagnostics Inc.'s clients opt for a series of tests
called TestSure, says Barry Sample, director of science and
technology at Quest. TestSure adds an additional $2 to the
cost of the drug test, which can vary from $16 to $28.

Syva Co., a
unit of diagnostic company Dade Behring based in Deerfield,
Ill., says its adulterant-screening products have seen 50%
growth over the past two years, while Roche Diagnostics, a
division of Switzerland's
Roche Holding AG, says sales for its similar Intect 7 test
strips have increased 77% since 1998.
Quest says
oxidants, a common agent in adulterants, are being found less
frequently. Of the approximately 6.3 million tests tracked by
Quest's Drug Testing Index in 2001, a scant 0.54% tested
positive for an oxidizing adulterant, compared with 0.92% in
2000 and 1.7% in 1999.
Government
guidelines due next year would make testing for adulterants
mandatory for federal and safety-sensitive workers, like
pilots and truck drivers.
That could
prompt the private sector to follow suit and use tests for
adulterants with every drug test, says Jim Wright, director of
compliance at DISA Inc., a Houston-based drug-testing advisory
firm.
Some in the
industry believe that nonurine tests, such as hair and
oral-fluid tests, will be the winning approach. More companies
are using these tests, such as Cambridge, Mass.-based
Psychemedics Corp.'s hair tests and oral-fluid tests from
OraSure Technologies Inc. in Bethlehem, Pa., which are
marketed as impervious to current adulterants. Hair tests
liquefy hair to get at drug traces deposited in the center of
strands over long periods of time, an approach that is said to
defeat foiling shampoos that clean the outside of hair.

Meanwhile, both
tests are administered by or in front of another person -- an
inch-size snip of hair at the root or a swab of saliva --
eliminating private time in a bathroom when urine samples can
be altered. Another option is on-site spot urine sampling
devices used, for example, when a candidate arrives to
interview, to minimize risk of advanced planning to thwart the
test.
Finally, the
law is increasingly on the industry's side. In November, North
Carolina joined New Jersey, Texas, Nebraska and Pennsylvania
in criminalizing drug-test foiling; neighboring South Carolina
outlawed adulterants in 1999, imposing fines of up to $5,000
and three years in prison.
Meanwhile,
industry lobbyists are shooting for federal legislation,
according to Laura Shelton, executive director of the Drug and
Alcohol Testing Association. "I think right now it's just a
matter of finding out who's in Congress and what is the right
approach as far as introducing legislation."
Sometimes
foiling the foilers comes down to individual determination.
Syed Hussain, owner of an Examination Management Services Inc.
testing branch in midtown Manhattan, recalls one man who came
for a hair test shaved head to toe -- not once, but twice. The
third time, at the client company's suggestion, Mr. Hussain
whipped out a razor and shaved the stubble on the man's head.
"They cannot
beat the system," Mr. Hussain says.

Foiling Products
|
|
Urine tests Donor gives
sample at testing center. The test screens for signs of
drug usage one to 30 days prior (window depends
primarily on the drug type). |
The industry "gold
standard," these tests have withstood legal challenges
and have been around longest. |
Donor alone in bathroom.
The foiling industry has had years to develop
strategies. |
A range of drinks, pills,
and urine additives of varying efficacy. If outdated,
the additives can be detected in the sample.
|
|
On-site urine tests Donor
gives sample on the spot, usually without prior warning.
The collection devices themselves, usually cups, can
reveal signs of drug usage, one to 30 days prior (window
depends primarily on the drug type). |
Donor lacks prior
knowledge of test. Results available in minutes.
|
Donor alone in a bathroom.
Devices can be read incorrectly. |
Because detoxifying drinks
must be taken at least 45 minutes ahead of a test, they
won't work for surprise tests. Donor must use urine
additives. |
|
Oral-fluid tests Donor
sticks a swab in mouth in front of administrator. The
test screens for signs of drug usage one to three days
prior. |
Donor lacks privacy and
prior knowledge of test. |
Not yet fully tested in
courts. |
Detoxifying mouthwashes
purport to coat the mouth with solution and stop saliva
flow for 30-40 minutes, preventing the testing lab from
obtaining a positive reading. |
|
Hair tests Administrator
cuts about 60 strands near a donor's scalp (or
elsewhere) and liquefies sample to wash out
contaminants. The test screens the wash for signs of
drug usage in the past 90 days. |
Donor lacks privacy. Have
withstood legal challenges. |
Will not detect recent
(one-to-seven day) usage. |
Shampoo products coat the
hair with a compound that is said to destroy traces of
illicit drugs released when the hair specimen is
dissolved for testing. |
*All
tests detect at least marijuana (THC), cocaine, opiates,
amphetamines and PCP. Positive samples are often verified,
as above tests are screens, by another test called gas
chromatography-mass spectrometry.
