Prescription Pain Releiver Abuse up Nearly 40%

A review of the data shows that drug abuse rates among workers have been stagnant for past decade... drug abuse is NOT declining.

Any statement that workplace drug abuse is lower, would be unsupportable by the findings.

The data does potentially indicate that that drug abusers have learned to cheat urine-based drug tests. This being supported by research recently concluded by the U.S. Government General Accounting Office (GAO) noting that cheating urine-based testing is easily accomplished and virtually undetectable.


The report also neglects to point out the opiate detection rates continue to climb. .. particularly oxycodones have gone up nearly 40% in one year!

" Use of Methamphetamine Among U.S. Workers and Job Applicants Drops 22 Percent in 2007 and Cocaine Use Slows Dramatically, Reports Quest Diagnostics"

Findings from Quest Diagnostics Drug Testing Index® also show that overall drug positivity remains at record lows

MADISON, NJ, March 12, 2008 — The percentage of positive tests for methamphetamine among U.S. job applicants and workers in the general U.S. workforce dropped more than 22 percent between 2006 and 2007.

These findings, from the Quest Diagnostics Drug Testing Index®, reflect the reversal of an upward trend in use of the drug by more than 73 percent from 2002 to 2004. These data were released today by Quest Diagnostics Incorporated (NYSE: DGX), the nation's leading provider of employment-related drug testing services.


The report also shows that positive tests for cocaine in the general U.S. workforce were down 19 percent between 2006 and 2007 and that overall drug use, among workers subject to drug testing, remains at an all-time low.

Methamphetamine, the most commonly abused type of amphetamine, increased in production and trafficking during the 1990’s to become the most prevalent illegally manufactured synthetic drug in the United States. Analysis of the Quest Diagnostics Drug Testing Index, released semi-annually, suggests that efforts to reduce illicit, clandestine production of methamphetamine may be having an impact on workplace positive tests for the drug.

"The fact that America's workers are using cocaine and methamphetamine at some of the lowest levels in years is further evidence of the tremendous success that law enforcement is having at impacting the nation's illicit drug supply," said DEA Acting Administrator Michele M. Leonhart. "DEA will continue its relentless assault on the drug supply to help keep these dangerous drugs out of our neighborhoods."

While the 2007 Quest Diagnostics Drug Testing Index shows that positive methamphetamine tests have decreased, it also indicates that the use of amphetamine in the general workforce has increased slightly, by about five percent. Testing for methamphetamine and amphetamine was conducted among employees and applicants in the U.S. workforce tested for the class of drugs called amphetamines.

"Although some may conclude that there is a reduced availability for methamphetamine, the fact that our data show an increase in amphetamines suggests that some workers might be replacing one stimulant drug for another in the larger drug class of amphetamines," said Barry Sample, Ph.D., Director of Science and Technology for Quest Diagnostics' Employer Solutions division.

Methamphetamine and amphetamine are both types of stimulants, which typically are used by individuals to increase alertness and relieve fatigue. Stimulants are also used for euphoric effects or to counteract the "down" feeling of tranquilizers or alcohol. Possible side effects of stimulants include increased heart and respiratory rates, elevated blood pressure, dilated pupils and decreased appetite. High doses may cause rapid or irregular heartbeat, loss of coordination or collapse. Indications of possible misuse may include excessive activity, talkativeness, irritability, argumentativeness or nervousness.

Cocaine Use Continues to Decline

The Quest Diagnostics Drug Testing Index shows that the percentage of positive tests for cocaine was down 19 percent among the U.S. general workforce since the first half of 2007 - the largest single-year drop since 1997. Positive tests for cocaine among the general workforce declined to 0.58 percent in 2007 from 0.72 percent in 2006.

Overall Drug Use Remains at All-Time Low

Additionally, drug use by employees remains at its lowest level since Quest Diagnostics began publishing the Drug Testing Index in 1988. Among the combined U.S. workforce, only 3.8 percent of the tests had positive results — the same level reported in 2006 — compared to a high of 13.6 percent in 1988. Further, among safety-sensitive federal workers only, the Drug Testing Index showed that drug use was at an all-time low of 1.8 percent of the tested work force.

The 2007 Drug Testing Index is a summary of results from 8.4 million workplace drug tests performed by Quest Diagnostics between January and December 2007. Results are based on tests that Quest Diagnostics performs for employers that conduct pre-employment, random or for-cause drug testing. For more information, see additional results below.

About the Drug Testing Index

The Drug Testing Index is published as a public service for government, media and industry and has been considered a benchmark for national trends since its inception in 1988. It examines positivity rates — the proportion of positive results for each drug to all such drug tests performed — among three major testing populations: federally mandated, safety-sensitive workers; the general workforce; and the combined U.S. workforce. Federally mandated, safety-sensitive workers include pilots, bus and truck drivers, and workers in nuclear power plants, for whom routine drug testing is mandated by the U.S. Department of Transportation and the Nuclear Regulatory Commission.

Kansas House approves bill to require drug testing in ‘major’ wrecks.

Drivers and passengers involved in “major” traffic wrecks in Kansas would be required to submit to drug testing, if a bill approved by the state’s House becomes law.

State law now allows law enforcement officers to order drug testing, if there is “reasonable suspicion” that the person is under the influence.

The House voted 117-5 to forward a bill to the Senate that would require truckers and other drivers, as well as their passengers, to undergo drug testing when they are involved in certain types of wrecks.

Officers would no longer need a presumption of a drug violation to force drivers to submit to the testing.

Supporters say changes are needed to make it easier to test people involved in wrecks resulting in fatalities or serious injuries. The bill would allow law enforcement to collect evidence for potential criminal prosecutions, they say.
Opponents say it is unconstitutional to force someone to submit to a blood or urine test if there is no probable cause to suspect them of a crime.
A provision added to the bill would permit people to refuse to a test. Taking that route, however, could result in loss of driving privileges.
Another change to the bill would authorize officers to waive the test requirement if they believe the actions of the driver did not contribute to the wreck.

The bill – HB2617 – has moved to the Senate Judiciary Committee.

On-site Oral Fluid / Saliva Drug Screens - Accurate

Journal of Psychoactive Drugs

A comparison between instant and laboratory oral fluid analysis among arrestees. Yacoubian GS; Wish ED.

Research studies that collect biological measures of drug use have traditionally utilized laboratory urinalysis.

Several recent studies have also documented the utility of laboratory oral fluid (OF) analysis.
A new method of drug testing -- instant OF technology -- may offer a quicker, equally accurate alternative to laboratory OF assays.
To date, however, no field studies have compared the two methods.

In the current study, an instant OF test (Avitar ORALscreen (TM)) was administered to adult arrestees surveyed through Maryland's Substance Abuse Need for Treatment among Arrestees (SANTA) study.

Following a research interview, a second OF sample was collected (Avitar ORALconfirm (TM)) and shipped to the manufacturer's laboratory for analysis.

The Avtiar ORALscreen instant OF test was:

96% sensitive and 83% specific for cocaine,

100% sensitive and 75% specific for opiates, and

100% sensitive and 94% specific for marijuana.

Courts Uphold Workplace Drug Testing - Once Again

Alberta Court of Appeal ruling upholds construction workplace drug testing
(Source: Canadian News)

EDMONTON - Construction and energy companies are happy with an Alberta court ruling that upholds the right of employers to test workers for drugs.

The Alberta Court of Appeal's decision overturned a lower court judgment that said Kellogg, Brown & Root Co. discriminated against a man in 2002 when it fired him from an oilsands project near Fort McMurray after he tested positive for marijuana.

John Chiasson, who admitted to being a recreational pot smoker, filed a complaint with the Alberta Human Rights Commission, which ruled against him. The commission said there needs to be a balance between an individual's human rights and the needs of an employer in protecting others.
But Court of Queen's Bench Justice Sheilah Martin then ruled in his favour. She said he should have been treated the same as someone with a drug addiction, which is considered a disability in human rights case law.

The panel of three Appeal Court justices disagreed. The judges said it is legitimate for Kellogg, Brown & Root to presume that people who use drugs at all are a safety risk in an already dangerous workplace.

"We see this case as no different than that of a trucking or taxi company which has a policy requiring its employees to refrain from the use of alcohol for some time before the employee drives one of the employer's vehicles," the justices wrote.
"Extending human rights protections to situations resulting in placing the lives of others at risk flies in the face of logic."

Kellogg, Brown & Root, one of the largest construction firms in the world, was helping to build an expansion to Syncrude Canada's plant at the time of Chiasson's case and is still active in the oilsands.
Andrew Robertson, a lawyer for the company, said the Appeal Court's decision is important to energy and construction industries.

"It is refreshing to see the Alberta Court of Appeal factor in risk management in safety-sensitive workplaces in a circumstance when there had been a recent focus on human rights issues," he said.
Heather Browne, a spokeswoman for Texas-based Kellogg, Brown & Root, hailed the ruling.
"KBR is a leader in workplace safety, and maintaining that commitment is the company's top priority," Browne said Wednesday.

"The court ruling upholds that commitment and we look forward to continuing our work in that regard."
Robertson noted that the Alberta appeal justices did not follow an Ontario Court of Appeal's decision in a similar case that said employees who test positive for drugs are to be dealt with as if they have an addiction even if they don't.

He said courts in provinces outside of Alberta and Ontario hearing similar cases will now have two different precedents to refer to.
Commission lawyer Janice Ashcroft said the Court of Appeal ruling will be reviewed before determining whether to seek leave to have the case heard by the Supreme Court of Canada.
"It is important to employers and employees to clarify what is the role of human rights when it comes to drug testing," Ashcroft said.

"This affects a lot of people and it is important. The commission does have a duty to ensure that the rights of all Albertans - both employers and employees - are balanced in this respect."
During the original court case, officials with oilsands giant Syncrude testified that the company's lost-time rate from accidents has dropped in part because of drug and alcohol testing.
Syncrude, Suncor, Albian Sands and other major oilsands heavyweights test their employees for drugs before they are allowed on jobsites.

Kara Flynn, a spokeswoman for Syncrude, said that in a broad sense, the Appeal Court ruling supports the company's drug-testing policy and goals.

"Any judicial decisions that support that are greatly appreciated," she said.
The impact of the ruling is already starting to ripple beyond Alberta's boundaries.
Phil Hochstein, president of the Independent Contractors and Business Association in British Columbia, said while workplace drug testing is common on major projects in Alberta, it is the exception in B.C.
He expects that is going to change.
"I think that workplace testing of construction workers is probably an issue whose time has come," he said from Vancouver.
"I think this case is going to spur more of this jobsite testing, not only on big industrial jobs, but on commercial and institutional jobs throughout the country."

Urine DOT Drug Testing Not Working - New Government GAO Report

Now even the US Government knows the obvious ....

Drug testing without observed specimen collection, is a waste of time and money.

Private interest groups, consisting largely of urine drug testing laboratories, urine-centric TPA's, occupational health clinics, some unions, as well as a select group of archaic government bureaucracies (DOT, FAA, etc.) continue to exclusively support urine-based testing vs. superior, user-friendly technologies - most notably oral fluid / saliva and hair-based drug screening.

Oral fluid / saliva and hair-based drug screening technologies allow for observed specimen collection and are relatively non-invasive vs. traditional urine drug testing. Oral fluid delivers information on "current" / "on-the-job" drug and/or alcohol use, while hair detects "historical drug abuse".

Oral fluid / saliva is suitable for random, post-accident, and reasonable suspicion testing, and also can be used for pre-employment testing.

Hair is most appropriate for pre-employment testing, especially for employers that wish to track drug use history for a period of up to 90 days.

The DOT and other government agencies, including "regulatory agencies" such as SAMHSA are largely to blame for the continued emphasis upon traditional urine-based testing, and ultimately serving to help perpetuate America's problem with substance abuse.

Why? Government agencies resist moving to newer technologies either due to the fear of having to "do more work", and/or are impacted by private interest groups with heavy lobbying budgets and well established "old boy networks".

In their defense, the DOT claims "success" by noting a "2% positive rate". This is a blatant misuse of statistics. Of course the is only a 2% positive rate... as most drug abusers are cheating the test!

As noted below, if drug testing involved observed specimen collection, and/or more stringent techniques the positive rate soars to 10%.

Urine-based drug testing is simply:

1. too difficult, costly, and noxious to apply consistently and on a corporate-wide / industry-wide basis,

2. prone to drug abusers "beating the test".

Several documented cases support the above facts:

For example, a recent construction site that had a low "positive rate" using tradition urine drug testing, but had several site issues and eventually discovered hypodermic needles on-site.

When they implemented Avitar's oral fluid-based testing, conducing a full site-based random screen, the positive rate registered 20%!

Urine testing laboratories, in most cases, are not able to determine if urine samples are adulterated or substituted, other than in the most basic and severe cases.

Despite this fact, they continue to spread misinformation, claiming the opposite.

The Director of Workplace Drug Testing for SAMHSA is on record, testifying before Congress, that detect adulterants, that labs can only detect a very small fraction of the many products available on the Internet available to beat urine-based drug tests, and that substituted drug free urine and synthetic urine also are undetectable.

GAO: Easy to cheat on trucker drug tests

Three-quarters of testing sites don’t provide secure conditions, report finds

The Transportation Department estimates that fewer than 2 percent of truck drivers test positive each year for controlled substances.

But when Oregon conducted its own tests, 9 percent of truck drivers tested positive.

Dozens of products on the Web are marketed to truckers as fail-safe ways to defeat the mandatory drug tests.

WASHINGTON - Undercover federal investigators discovered that it was surprisingly easy to cheat on random drug tests designed to catch truck drivers who use drugs, NBC News has learned.

Undercover investigators with the Government Accountability Office (GAO), the investigative arm of Congress, used bogus truck driver’s licenses to gain access to 24 drug-testing sites.

They found that 75 percent “failed to restrict access to items that could be used to adulterate or dilute the [urine] specimen, meaning that running water, soap, or air freshener was available in the bathroom during the test.”

The GAO team also bought drug-masking products over the Web and was able to mix them with real specimens at the drug-testing sites “without being caught by site collectors,” the agency said in a report scheduled to be made public ThursdayDrug - screening labs never realized that there was a problem.

“Every drug masking product went undetected by the drug screening labs,” said the report, a copy of which was obtained by NBC News.Rep.

Jim Oberstar, D-Minn., chairman of the House Transportation and Infrastructure Committee, said the report was “frankly astonishing and shocking and dismaying.

You can manipulate the tests, you can mask substance abuse and go undetected on the roadways.”Oberstar, who planned to hold a hearing Thursday, said the drug-testing system was broken and was placing other drivers in danger.“It fails, it is not sufficient, it is not protecting the public interest,” he said.

How many are cheating?

The Transportation Department estimates that fewer than 2 percent of truck drivers test positive each year for controlled substances in random federal tests.

But when Oregon law enforcement officials conducted their own random tests this year, 9 percent of truck drivers tested positive.

Dozens of products widely available on the Web are marketed to truckers as fail-safe ways to defeat the mandatory drug tests.

“My first reaction was total disbelief. I just felt sick,” said Kathleen Ellsbury, whose husband, Tony Qamar, was killed two years ago when a truck driver in Washington state lost his load of logs on a curve, crushing Qamar’s car.

Also killed was Daniel Johnson, a fellow seismologist at the University of Washington.Ellsbury learned later that the truck driver, who was sentenced to 4½ years in prison for vehicular homicide, had previously been convicted of possessing methamphetamines and that he had meth in his blood at the time of the crash.

“The system has big holes, let’s say that,” said Ellsbury, who said she had a message for truck drivers who might be tempted to cheat:

“I’d like to be standing right outside the bathroom and hold up a picture of my husband — remind them there's consequences.”

Truckers promise to do betterSpokesmen for the trucking industry said truck drivers were among the safest drivers on the road, with much lower rates of drug use than the general population. Still, they said, having roughly 30,000 drivers test positive each year was unacceptable.
