Estimation of Drug Expenditures, Consumption and Supply
The Office of National Drug Control Policy sponsored research to update previously published estimates of illegal drug availability on the streets of the United States based on both demand and supply data indicators. The demand-based methodology, published as What America’s Users Spend on Illegal Drugs (WAUSID), estimates the magnitude of drugs in the United States by calculating consumption based on surveys of drug use prevalence and frequency. The supply-based methodology, published as Drug Availability Estimates in the United States (DAEUS), estimates the magnitude of drugs in the United States based on supply indicators such as production estimates and seizures. Estimates were developed for the four major drugs (cocaine, heroin, marijuana, and methamphetamine) through 2006. Estimates through 2010 are currently in development.
