Implications of Inertia for Assessing Drug Control Policy: Why Upstream Interventions May Not Receive Due Credit

Caulkins, Jonathan P. - 2007

Background: There is ongoing interest in assessing the effectiveness of various drug control strategies, including policy intended to reduce initiation and prevalence. Compartmental models of trajectories of drug use have been developed that demonstrate that drug “systems” display...
