This paper examines how, in order to develop effective treatment programs for drug addicts, it is essential to maintain a
basic knowledge of the physiological basis of their cravings. It evaluates how the ability to explain the neuro-scientific effects of drug use allows those that are responsible for prevention to provide potential users with deterrents that are less dogmatic and more circumspect. It looks at how
neuroscience has developed a new understanding of the reasons for addiction and how behavioral neuroscience has taught us that humans, like other animals, crave certain
pharmaceutical agents. Studies have enabled scientists to better understand the neuro-chemistry of pleasure and of cravings.
