can abusing over the counter painkillers containing codiene cause brain apathy

The abuse of over the counter painkillers containing
codeine may very well cause brain apathy for the following
reasons.

As far back as 1972 scientists discovered that the
human brain actually has receptors that work specifically to take in substances such as
codeine, morphine, and heroin. The reason for it is because these substances have a way
to attach themselves, or combine themselves in those receptors the way endorphins (good
substances) can.  If you think about it, if endorphins produce in us a feel-good feeling
by attaching to the natural receptors in the brain, so can heroin, codeine, and morphine
since all these substances have a very similar make-up.

The
way that codeine would work in your brain would be by attaching itself to the endorphin
receptors and controlling the amount of endorphin that rushes through our bodies. It can
either block or speed the production of endorphin. In a normal person who takes codeine
for specific reasons, and within a small period of time, this will not be a
problem.

However, a person whose social and
phsychological well-being is based on the control of senses and emotions, will find that
self-medicating with codeine, or any other substance of the kind, will create a yo-yo
effect of highs and lows. Ultimately, this is what a true addict is searching for: A way
to control highs and lows and to produce them at once.  If the substance is removed, the
withdrawals begin. Some individuals run to get larger dose of drugs to counteract them,
and some because they develop tolerance. So, in other words yes your brain can develop
apathy with the effects of codeine in the system.
