title: Efficiency evaluation of a police operation to fight the drug plague: distribution unit weight as an objective index.
abstract: Lod, a city near Tel-Aviv, is considered the main drug distribution center in Israel. A major police undercover operation in Lod, lasting close to a year, was terminated in May 2003. The success or failure of such an operation is frequently measured by the number of arrests made, the hierarchical level of the dealers arrested, the number of drug stations closed down, and the decrease in heroin seizures following the operation. In this work we suggest using an additional parameter, which has a scientific, objective basis, namely, comparing the changes in the average user weight unit ("dose") before and after the operation. We found that prior to the operation the average weight per unit was 1.1 g. Three months after the operation terminated the average weight per unit had decreased to 0.8 g and remained there for at least 4 months before rising again.
