A number of supply and demand-side indicators provide support for heroin's 're-incubation' in an era of crack cocaine's decline. The present paper ass esses the extent to which these and other trends converge with reports of h eroin market participants operating on the streets of a large midwestern Am erican city. Focal areas of investigation include quality, price and drug u se conduct norms. Conceptualization centres on the short and long-term impl ications of heroin's reported resurgence on emergent street drug markets.
