The rational addiction (RA) model of Becker and Murphy (Becker GS, Murphy KM. A theory of rational addiction. J Pol Econ 1988; 96(4): 675–700) has rapidly become one of the standard models in the literature on addictive behaviour. This paper reviews some theoretical issues surrounding its use, and indicates areas in which caution should be used in applying this model. Copyright © 2000 John Wiley & Sons, Ltd.
