On-site Workplace Drug Screening increases 31% in 2012
On-site Workplace Drug Screening increases 31% in
2012
>
> The number of on-site workplace drug tests
has increased 31% over the last year reports the New Zealand
Drug Detection Agency (NZDDA) in the release of its annual
statistics. In 2012 NZDDA conducted 68,561 on-site drug
screening tests, up from 52,124 tests carried out in 2011.
This follows an increase of 77.7% from the 29,513 tests
carried out in 2010.
>
> Screening for alcohol in the
workplace, in 2012 NZDDA conducted 39,369 breath alcohol
tests – up 32% from 2011 when 29,791 tests were carried
out. In 2010 there were 13,821 tests conducted. Of the
39,369 alcohol tests performed last year, 0.4% of the tests
were positive, the same figure as for 2011. In 2010, 1.9% of
alcohol tests were positive.
>
> NZDDA’s chief
executive Chris Hilson says, “The rise in the number of
on-site workplace drug and alcohol tests in 2012 illustrates
that many more employers are taking workplace safety very
seriously. Most of our testing takes place in the
safety-sensitive sectors such as forestry, transport and
construction – sectors in which it’s vital for employee
safety but also for their customers and suppliers and, in
some cases, the general public. There’s no second chance
if there’s any impairment from drugs and alcohol in those
workplaces.”
>
> NZDDA is New Zealand’s only fully
compliant AS/NZS4308:2008 International Accreditation New
Zealand (IANZ)-accredited on-site drug and alcohol testing
provider. The company is considered to be a leader in its
field.
>
> All NZDDA’s workplace drug tests are
retested at the Canterbury Health Laboratory (CHL) for the
legally required independent verification. All testing is
carried out to the rigorous AS/NZS4308:2008 standard.
CHL’s head scientist Grant Moore says, “CHL uses highly
sensitive equipment which identifies individual drugs,
rather than drug classes. So we can pinpoint a drug such as
Ecstasy rather than listing it as an amphetamine-type
substance. This is a very important safeguard as it helps
ensure prescription drugs aren’t confused with illegal
drugs if they’re in the same toxicology
group.”
>
> Of the 68,561 on-site drug tests NZDDA
carried out in 2012, 6.4% tested ‘non-negative’, an
indication that the presence of a drug is detected. This is
a slight decrease from the 2011 figure when 7% of tests were
found to be non-negative.
>
> Cannabis (THC) continues
to be the most frequently detected drug in workplace drug
screening, with 71% of the non-negative tests detecting this
drug, up from 68.5% in 2011. In 2010 the figure was 70.3%.
Opiates (including codeine) were detected in 18% of
non-negative tests, compared with 15.9% the previous year,
and 16.2% in 2010. Methamphetamine was found in 6% of
non-negative tests in 2012, 9.1% in 2011 and 16.2% in 2010.
Benzodiazepines were detected in 1% of non-negative tests in
2012, down from 1.2% in 2011 and 2% in 2010. Cocaine
hasn’t been detected at all in tests in 2012 and 2011, and
0.2% of non-negative tests in 2010.
>
> Mr Hilson says
it’s pleasing to be seeing a downward trend in the
detection hard drugs such as benzodiazepines and
amphetamines, and no cocaine detected in on-site workplace
drug testing over the last three years.
>
> NZDDA’s
2012 statistics don’t include synthetic cannabis data says
Mr Hilson. “NZDDA began testing for synthetic cannabis in
the latter part of last year with the introduction of
FDA-approved (US Food & Drugs Administration) test strips,
so our data only covers a few months and can’t be included
in our annual reporting. We do have, however, strong
anecdotal evidence that its use is on the rise. We’ll be
including synthetic cannabis test results in our 2013
statistics.”
>
> Hair testing data is provided for
the first time in this 2012 report. Hair testing provides
evidential results which give a history of drug and/or
alcohol use over the previous 90 days. Two hundred tests
were conducted in 2012; 65 of those returning positive
results – 38 tests detected cannabis and 29 showed up
methamphetamine use. Mr Hilson says hair testing mostly
takes place for ‘white collar’ pre-employment testing
and the testing of witnesses in court, in particular the
Family Court.
>
> Workplace drug and alcohol testing
takes place mostly in safety sensitive industries such as
construction, forestry, freezing works, manufacturing,
mining, oil and gas, transport and waste.

>
NZDDA’s 2012 statistics analyse the test reasons
(pre-employment, post-incident, re-test, random, reasonable
cause or voluntary) on a national basis as well as
regionally and by North/South Island, by sector and by drug
type detected.
>
> Overwhelmingly 31% of non-negative
results detected are testing for ‘reasonable cause’; in
2011 this was 30%. At the other end of the scale random
testing records 6% of non-negative test results, up from 5%
the previous year. Cannabis is detected more frequently in
traditional cannabis growing areas such as Northland, the
Bay of Plenty, and the North Island’s east coast.
Wellington also has a high cannabis usage rate.
>
> In
addition to workplace drug and alcohol testing, NZDDA also
offers advanced drug and alcohol manager and training
programmes, as well as assisting clients in designing and
implementing workplace drug and alcohol policies.
>
>
Andrew Schirnack, partner of specialist employment law firm
LangstonHudsonButcher says, “Having a carefully drafted
policy that is both appropriate to the particular workplace
and properly introduced is the starting point for lawful
workplace drug and alcohol testing. Employers should then
take care to abide by their own policies when undertaking
testing. The Employment Court has made it clear that it
won’t tolerate employers departing from the rules
they’ve set for themselves in policy.”

NZDDA’s chief executive Chris Hilson concludes,
“Employers have a responsibility to provide a safe
workplace for all, and in particular in safety sensitive
sectors. We’re heartened to see that more employers are
training their managers and supervisors, and also their
employees, in workplace policy planning and
implementation.
>
> “Workplace safety is vital to
the health of New Zealand industry. On a personal level
people’s heath and livelihoods are at stake. Having the
ability to accurately test and identify the presence of
drugs and alcohol in the workplace has got to be good for
business and, ultimately, the New Zealand
economy.”
