Everyday, there are several millions of people that are increasingly unable to combat their frustrating and even fatal romance with getting high and/or experiencing Bnormal^ feelings of well-being. In the USA, the FDA has approved pharmaceuticals for drug and alcohol abuse: tobacco and nicotine replacement therapy. The National Institute on Drug Abuse (NIDA) and the National Institute on Alcohol Abuse and Alcoholism (NIAAA) remarkably continue to provide an increasing understanding of the intricate functions of brain reward circuitry through sophisticated neuroimaging and molecular genetic applied technology. Similar work is intensely investigated on a worldwide basis with enhanced clarity and increased interaction between not only individual scientists but across many disciplines. However, while it is universally agreed that dopamine is a major neurotransmitter in terms of reward dependence, there remains controversy regarding how to modulate its role clinically to treat and prevent relapse for both substance and non-substance-related addictive behaviors. While the existing FDA-approved medications promote blocking dopamine, we argue that a more prudent paradigm shift should be biphasic-short-term blockade and long-term upregulation, enhancing functional connectivity of brain reward circuits.

Scientific explorations from around the globe agree that
substance and non-substance-seeking behaviors are
considered an endemic societal problem affecting multimillions.
Certainly, we have come a long way since Bill Wilson and
Dr. Bob Smith began their crusade in 1933 embracing the
BCambridge^ theories and doctrines, resulting in the most
powerful anti-alcohol/drug program and fellowship in the
worldAlcoholics/Narcotic Anonymous. Many years after
Jelnicks famous article in 1956 providing the medical
profession with the Bconcept of alcoholism as a disease,^ the
American Society of Addiction Medicine (ASAM) espoused
a new definition of addiction indicating that BAddiction is a
primary, chronic disease involving brain reward, motivation,
memory and related circuitry^; it can lead to relapse,
progressive development, and the potential for fatality if not treated.
While pathological use of alcohol and, more recently,
psychoactive substances has been accepted as an addictive disease,
developing brain science has set the stage for inclusion of the
process addictions, including food, sex, shopping, and
gambling problems, in a broader definition of addiction as set forth
by the American Society of Addiction Medicine in 2011 [1].
To carry out this review, we searched a number of
important databases including the following: filtered resources
Cochrane Systematic Reviews, DARE, PubMed Central
Clinical Queries, National Guideline Clearinghouse;
unfiltered resourcesPsychINFO, ACP PIER, PsychSage,
PubMed/MEDLINE. The major search terms included the
following: dopamine agonist therapy for addiction, dopamine
agonist therapy for reward dependence, dopamine
antagonistic therapy for addiction, dopamine antagonistic therapy for
reward dependence. Our results produced the following:

According to Belcher et al., drug addiction is characterized
by a compulsive drive to take drugs despite serious negative
consequences and is a disorder that involves complex
interactions between genetic and environmental variables [3]. For
example, undoubtedly, heroin addiction is a complex phenomenon
of the brain involving both affective and cognitive processes [4].
It has been found that in heroin-dependent individuals, there is
increased white matter intensity in the frontal area and decreased
gray matter density in the bilateral prefrontal cortices and in the
temporal regions compared to healthy subjects [5]. It was also
found that there is a high accuracy in the activation pattern
differences between heroin-dependent subjects and healthy
individuals during resting-state brain activities. These
differences of activation patterns included orbitofrontal cortex
(OFC), hippocampal/parahippocampal region, amygdala,
caudate, putamen, as well as the insula and thalamus [6].
Moreover, similar effects were found for alcohol as well.
Specifically, Luhar et al. [7] compared non-smoking
non-alcoholicsalcoholics who smoke had volumetric abnormalities in
pre- and paracentral frontal cortical areas and rostral middle
frontal white matter, parahippocampal and temporal pole
regions, the amygdala, the pallidum, the ventral diencephalic
region, and the lateral ventricle. The comorbid group (...truncated)
