Technical Report for 'The Price and Purity of Illicit Drugs: 1981 Through the Second Quarter of 2003'   [open pdf - 884KB]

"The purpose of this technical report is to provide detailed documentation of all programming and statistical activities involved in the construction of the price and purity series presented in 'Price and Purity of Illicit Drugs: 1981 Through Second Quarter of 2003', a companion report prepared for the Office of National Drug Control Policy (henceforth referred to as the main report). This technical report contains information on the precise steps taken to (a) acquire the data, (b) assess the quality of the data, (c) clean the data, (d) use the data to generate city-specific price and purity series, and (e) build national indices of price and purity from city-specific estimates. It serves as a roadmap for anyone interested in replicating the results presented in the main report. Because decisions had to be made at various stages about which data to use and how to use them, this document also provides a justification for the decisions made throughout the development of the main report."
