Abstract
Although the term "addiction" is still widely used current theorists and scholars are tending to use the term "dependence" in modern research and studies. People can become dependent not only on external substances that are ingested but also to risky behaviors such as gambling, extreme sports etc. In this respect anything that induces a pleasurable physiological change has the potential to lead to dependence or addiction. Brain cells have a central core covered by a sheath; at one end of the cell are roots at the other end "fronds". A charge is passed through the fronds to the fronds of another brain cell and neurotransmitters are released, these neurotransmitters are responsible for feelings of euphoria and heightened pleasure. Some substances mimic neurotransmitters or may cause receptors to cut out; the use of some substances (such as alcohol or opiates) may cause the brain to stop producing neurotransmitters leading to dependence.Orford and Heather (2003) have identified the puzzling aspect of addiction, the fact that although the addict wants to give up the addiction they often find themselves returning to the substance or action that they are dependent on.
