Contextual Interventions for Controlling Alcohol Drinking

The dynamics of an alcohol drinking population are subject to environment-specific control programs. The stochastic model is developed that includes populations of light, moderate, and heavy drinkers, interacting in two contrasting risk-level drinking environments. For colleges with serious drinking problems, the times to disappearance of serious drinkers show that environment-dependent control programs have lasting efficacy when they are implemented according to the risk level of the environments and not by simply focusing on heavy drinking.
