The price and purity of cocaine: the relationship to emergency room visits and death, and to drug use among arrestees.

This paper examines the relationship of the price and purity of cocaine to emergency room visits and deaths associated with cocaine use and to cocaine use among arrestees. A model is developed for the trend in cocaine prices at the retail level during the period January 1986 to December 1991. This trend is then compared to information on emergency room visits, medical examiner reports, and the percentage of arrestees testing positive for cocaine use over the same period. The principal conclusion is that there is a significant negative relationship between the estimated street price of cocaine and the level of related medical emergencies and deaths and the number of arrestees who test positive for cocaine.
