A study of the frequency of deaths resulting from the use of drugs and chemicals in Los Angeles County in the period 1947--1980 indicated that there was a substantial increase in the number of such deaths in 1968/69. This trend continued until 1976/77 when the number of deaths decreased, and the declining trend continued until 1979/80. An additional study in the period 1974--1981, based on the analyses of 35 drugs in biological samples taken in autopsies, showed that those drugs were more often present in overdose cases of death than in drug-related cases of death where drugs were not directly responsible fo the occurrence of death. Ethanol and phencyclidine were, however, more frequently found in drug-related cases of death.
一项对1947年至1980年期间洛杉矶县因使用药物和化学品导致的死亡频率的研究表明，1968/69年此类死亡人数大幅增加。这一趋势持续到1976/77年，之后死亡人数下降，且下降趋势一直持续到1979/80年。另一项基于对尸检时采集的生物样本中的35种药物进行分析的1974年至1981年期间的研究表明，与并非直接导致死亡的药物相关死亡病例相比，这些药物在药物过量致死病例中出现的频率更高。然而，乙醇和苯环己哌啶在药物相关死亡病例中更常被发现。
