How
Do Drugs Affect the Mind?
The
mind is our most important tool. With our mind, we solve the
problems we face in life. Drugs do several things that harm
one's ability to think or to be fully aware of the present surroundings.
These effects continue long after the effects of the drug appear
to have worn off.
Addictive
drugs activate the brain's reward systems. The promise of reward
is very intense, causing the individual to crave the drug and
to focus his or her activities around taking the drug. The ability
of addictive drugs to strongly activate brain reward mechanisms
and their ability to chemically alter the normal functioning
of these systems can produce an addiction. Drugs also reduce
a person's level of consciousness, harming the ability to think
or be fully aware of present surroundings.
Because
of the effects of drugs on the mind, a person with a history
of drug use isn't quite tracking with what is going on around
him. Right before your eyes, while apparently in the same room
as you are, doing the same things, he is really only partially
there and partially in some past events. The drug taker is not
moving in the same series of events as others. This can be slight,
wherein the person is seen to make occasional mistakes, or it
can be as serious as total insanity - where the events apparent
to him are completely different from those apparent to anyone
else. And it can be all grades in between.
It
isn't that the drug user doesn't know what's going on. It is
that he perceives something else going on instead of the actual
series of events that are happening around him. The person no
longer responds to the drug in the way that person initially
responded. So for example, in the case of heroin or morphine,
tolerance develops rapidly to the analgesic (painkilling) effects
of the drug. While the development of tolerance is not addiction,
many drugs that produce tolerance also have addictive potential.
The
fact remains that there is scientific research to support all
of these concepts. The question of whether addiction is genetic,
behavioural or biochemical does not have an absolute answer. The
distinguishing feature of this condition commonly called addiction
is the ability of the drug to dominate the individual's behaviour,
regardless of whether physical dependence is also produced by
the drug.
There
are a wide variety of treatment methods being used today, administered
based on whatever school of thought the treatment provider believes
in. With a 16% to 20% recovery rate based on statistical analysis
of national averages, the message is clear that we have a lot
more to learn if we are to bring the national recovery rate to
a more desirable level.
There
is a fourth school of thought that has proven to be more accurate.
It has to do with the life cycle of addiction.
This data is universally applicable to addiction no matter which
hypothesis is used to explain the phenomenon of drug dependency.
