War on Drugs: Heroin Price, Purity, and Quantities Seized Over the Past 10 Years

Pursuant to a congressional request, GAO provided information on the fluctuations in heroin's street price and purity levels, which are indicators of heroin availability, over the past 10 years, as well as data on heroin seizures, concentrating on seizures in New York City. GAO also provided information on the progress of the reduction in double-counting of drug seizures caused by multiple agencies reporting the same seizure.
