It has been a mystery why some people seem to be unable to overcome drug addiction, but the mystery is slowly being unravelled.

1. When Drug Testing Becomes a Reward System
It has been a mystery why some people seem to be unable to overcome drug
addiction, but the mystery is slowly being unravelled. The impact of various drugs
on brain functioning, and their ability to rewire
message signalling to the rest of the body, are
become less enigmatic with each study. As the
research continues, a new question is being asked:
Can addicts ever truly overcome their addiction? Are
once-addicts always attracted to their drug of choice,
and can the brain ever return to its original state? As
researchers attempt to find answers, it is important
to realise that there are people who do stop using
drugs and are able to resist succumbing to lure of
“getting high” again. For these people, random drug
and alcohol test in the workplace can become a
component of a personal reward system. Each
negative test reinforces success in the personal effort
to stay away from drugs.
Which Came First: Brain Abnormality or Drug-Induced Changes
The basis for a recent study reported in Biological Psychiatry began with questions
that went along these lines: Is a person using psychostimulants like cocaine
naturally more impulsive, and the drugs further alter the brain reward circuits,
increasing impulsiveness even more and eventually leading to addiction? Or do
brain abnormalities exist before addiction in a way that the abnormalities, and not
necessarily the drug effects on the brain, lead to addiction? 1 Another way to state
the problem is: Which came first, the abnormality or the drug-induced brain
changes?
To answer the question, a group of medical researchers conducted a study at the
Institute of Living at Hartford Hospital in which three groups of people performed
the same tasks. One was a control group made up of healthy individuals who do not
use drugs. The second group consisted of current cocaine users. The third group
had members who had not used cocaine for an average of four years. A very brief
description of the results is that people currently using cocaine and people who
were once addicted to cocaine have elevated impulsivity measures compared to the
control group. The measures were based on multiple brain regions associated with
reward processing. The possible interpretation of the study results is that the
people using cocaine or who once used cocaine had a pre-existing risk of
developing addiction.2
Drug Testing Becomes a Pat on the Back

2. Another implication of this study is that some people who stop using cocaine will
still retain some of their natural impulsivity, since it is not due entirely to the drug.
If further studies support the findings, it means that addiction recovery is a process
that lasts a lifetime. Workers who have ended drug abuse can benefit from reward
systems that encourage continued drug abstinence as they continually work to
overcome impulsive thinking that is a consequence of natural brain “wiring.”
For these employees, drug testing can become a “pat on the back” by reinforcing
success. Each negative drug test is proof the worker has stayed off drugs and is
doing a good job at managing their health. All too often, drug testing is viewed as a
management tool for detecting people using drugs, but there is another way to look
at it. Drug testing also shows who is not using drugs and these are the people to be
congratulated. A negative drug test to a person who was once addicted is a very
happy event.
As research studies continue to explore addiction, it is important for employers to
accentuate the positive elements of workplace health and safety that are the
ultimate targets of drug testing programs. CMM Technology (cmm.com.au) is an
