Additionally, drug addiction alters the dopamine systems natural levels, and results in the body being unable to balance the levels of dopamine due to the reduction of dopamine available for release. In conclusion, dopamine receptor gene has been attributed to an increase in the propensity for drug addiction, alcoholism, and thrill seeking behavior (Beaver, 2013).
Reward Dominance Theory
The study of neurology and neurotransmitters has led to the creation of the neurobiological theory known as the reward dominance theory (Walsh et al., 2012). The behavioral activating system and the behavioral inhibition system are two of the principal systems of behavioral control located within the brain (Walsh et al., 2012) .The reward dominance theory emphasizes two functions of systems of the brain : the behavioral approach system, and behavioral inhibition system (Walsh et al., 2012). Furthermore, the behavioral approach system is the system that determines what drives an individual towards rewards and satisfaction (Wright et al., 2008). In this regard, the behavioral approach system is made up of a collection of brain structures, and is primarily located in the frontal cortex, and the limbic system (Wright et al., 2008).
In regards to drug addiction, the limbic system is the primary pleasure centers of the brain due to the effects of dopamine (Walsh et al., 2012).Thus, a drug offender’s motivation and drug seeking behavior can partially be attributed to the brain and the
