Illegal Drug Price and Purity Report

摘要

This edition of the Illegal Drug Price and Purity Report provides cocaine, heroin, marijuana, hallucinogen, depressant, and stimulant prices in the United States from January 1998 through December 2001. In addition, purity levels are included for cocaine and heroin as is the delta-9-tetrahydrocannabinol (THC) content for marijuana. The price data were compiled from DEA field division reports. The highest and lowest reported prices during the year for each drug provide the national range. The wide range in kilogram prices reflects the following variables: buyer/seller relationship; quantity of kilograms negotiated (more kilograms = lower price); purchase frequencies; location (higher prices paid in outlying areas); purity (higher price paid for higher purity); and transportation costs. Purity information for cocaine and heroin comes from DEA's System To Retrieve Information from Drug Evidence (STRIDE). Purity data are based on STRIDE printouts of average purities for the 1-to-10-gram, 1-to-10-ounce, and 1-to-10-kilogram ranges. STRIDE is a computerized data base program used to record, collate, and display the results of qualitative and quantitative chemical analysis of all drug evidence submitted to the DEA laboratory system. The University of Mississippi's Marijuana Potency Monitoring Project provides THC levels for marijuana.
