Now of the 4 definitions listed above , only 1 , 2 , and 4 , are really scientific , 3 is more of a common usage definition . I should also point out addiction is usually defined as a compulsive behavior wherein an individual seeks out a stimulus as much as possible , generally to the point that they harm themselves or others the last part is rarely precise as to what counts as harm . 3 any harmful , depraved , or morbid condition , as of the mind or society His fascination with executions is a disease . The word disease literally comes from the word and prefix dis ease something that causes a lack of ease . I understand it is not scientific but I still think it is worth mentioning when determining what does and does not fit the real definition of disease . If you take that definition of addiction and remove the causes problems qualifier in its second half and I think we should because all habits cause at least one problem they take up time and energy , then we have no choice but to accept that addiction , though it may be a problem in many instances , is not a disease , because it represents our natural , inborn response to things that make us feel goodSome people are genetically predisposed to develop alcoholism . That alone does not disprove the statement I quoted but I would like to know how this idea fits in to your understanding of addiction .
