Posts Tagged ‘Neuroscience research. two models of drug use compared’

I saw  this new research—animal models of drug abuse together with the existence of a reward structure in the brain—as an entirely novel paradigm, full of promise in a world where the old model was visibly failing.

Below I have summarized the two models as I understand them to be. This  will be followed by discussion of what I regard as significant aspects of the neuroscience model.

 

The diagram below shows the differences between the two models as I understand them.

PSYCHO-ACTIVE DRUG ISSUES

 

ISSUE TRADITIONAL MODEL  NEUROSCIENCE  MODEL
EXPLANATION OF  WHY PSYCHO-ACTIVE DRUG PLANTS IMMEDIATELY  REWARD  USERS No explanation Drug plants contain chemical analogues of brain neurotransmitters; drugs can replace the latter, and  act on reward strata in human (+ animal)  brains.
INHERENT PATTERN OF DRUG USE  Moderate drug use until and unless addiction develops  Being biological in origin, initial drug use is reinforced, leading to  unrestrained drug use, in absence of existing or imposed restraints 
ROLE OF SOCIO-CULTURAL FACTORS INCL. LEGAL, ECONOMIC + PERSONAL  Adverse socio-cultural factors incl. individual psycho- pathologies lead to 

Excessive Drug  Use/Abuse

 

Positive socio-cultural factors +  accurate drug information alter   unrestrained drug use toModerate Drug Use
