The War on Drugs: Methamphetamine, Public Health, and Crime
1995年美国政府打击甲基苯丙胺前体的行动成功提高了毒品价格、降低了纯度，并减少了相关住院和逮捕，但未显著减少财产或暴力犯罪，且效果短暂。
In mid-1995, a government effort to reduce the supply of methamphetamine precursors successfully disrupted the methamphetamine market and interrupted a trajectory of increasing usage. The price of methamphetamine tripled and purity declined from 90 percent to 20 percent. Simultaneously, amphetamine-related hospital and treatment admissions dropped 50 percent and 35 percent, respectively. Methamphetamine use among arrestees declined 55 percent. Although felony methamphetamine arrests fell 50 percent, there is no evidence of substantial reductions in property or violent crime. The impact was largely temporary. The price returned to its original level within four months; purity, hospital admissions, treatment admissions, and arrests approached preinter-vention levels within eighteen months.
