The concept of �addiction� has been created to explain why people repeatedly behave in certain ways which are usually not socially approved of. Why? Because, blaming people for their �bad� behaviour draws attention, not to the circumstances within which the behaviour occurs - the context, but to the person them self: an example of the Fundamental Attribution Error. To avoid this (and casting the user into the role of helpless victim) the drug itself becomes the �bad� element -an �addictive� drug. Science explains (partly) the drug�s pharmacological action. This is then taken as proof and the explanation (addiction) is then seen as the cause of the �bad� behaviour (taking the drug).
