Abstract

The University of Mississippi has a contract with the National Institute on Drug Abuse (NIDA) to carry out a variety of research activities dealing with cannabis, including the Potency Monitoring (PM) program, which provides analytical potency data on cannabis preparations confiscated in the United States. This report provides data on 46,211 samples seized and analyzed by gas chromatography-flame ionization detection (GC-FID) during 1993-2008. The data showed an upward trend in the mean Δ(9)-tetrahydrocannabinol (Δ(9)-THC) content of all confiscated cannabis preparations, which increased from 3.4% in 1993 to 8.8% in 2008. Hashish potencies did not increase consistently during this period; however, the mean yearly potency varied from 2.5-9.2% (1993-2003) to 12.0-29.3% (2004-2008). Hash oil potencies also varied considerably during this period (16.8 ± 16.3%). The increase in cannabis preparation potency is mainly due to the increase in the potency of nondomestic versus domestic samples.

摘要

密西西比大学与美国国家药物滥用研究所（NIDA）签订了一项合同，以开展各种与大麻相关的研究活动，包括效力监测（PM）项目，该项目提供在美国查获的大麻制剂的分析效力数据。本报告提供了1993年至2008年期间通过气相色谱 - 火焰离子化检测（GC - FID）查获并分析的46,211个样本的数据。数据显示，所有查获的大麻制剂的平均Δ(9)-四氢大麻酚（Δ(9)-THC）含量呈上升趋势，从1993年的3.4%增至2008年的8.8%。在此期间，哈希什的效力并非持续增加；然而，平均年度效力从1993 - 2003年的2.5 - 9.2%变化至2004 - 2008年的12.0 - 29.3%。在此期间，哈希油的效力也有很大变化（16.8 ± 16.3%）。大麻制剂效力的增加主要归因于非国内样本与国内样本相比效力的增加。
