Abstract: In this talk, we investigate a stochastic heroin epidemic model. By constructing suitable stochastic Lyapunov functions, we establish sufficient conditions for the extinction of the drug users. Moreover, we also establish sufficient conditions for the existence of ergodic stationary distribution to the model, which reveals that the drug users will persist. The sensitivity analysis indicates that prevention would be more important than cure.
