Abstract This paper considers the spread of drug addiction when addiction is by taking one of two competing drugs available. Community is assumed to be closed and each individual is classified as belonging to one of three mutually exclusive groups: susceptibles, addicts and pushers. A deterministic model is presented in general form and, in a special case, the stochastic model is analysed. An illustration is also presented where the parameters take a specific set of numerical values.
