I have a problem with calling any obsessive activity an addiction. True addictions have clear withdrawal symptoms if the addictive agent is denied for more than a very brief period. Certainly research has shown that our brains respond to any activity we find pleasurable by releasing chemicals affecting areas of the brain's pleasure centers. We are biologicaly programmed to seek pleasure, sugar, sex etc. Although it has become popular to call any activity which can be overdone an addiction and their are some valid similarities in brain responses their are also significant differences. Does anyone really belive addicts could go three or four months without access to their addictive substance without a major effort. Certainly any obsessive activity can be very harmful, stamp collectng, computer games, etc. It is indeed rare for individuals to continue these activites even when they will clearly cause death, quite common in true addiction. I suspect calling an obsession addiction is more socially acceptable but I feari it may keep people with a real problem from seeking assistance and appropriate responses.
