Notably absent from the 2005 list were Afghanistan, the People's Republic of China and Vietnam; Canada was also omitted in spite of evidence that criminal groups there are increasingly involved in the production of MDMA destined for the United States and that large-scale cross-border trafficking of Canadian-grown cannabis continues.
值得注意的是，2005年的名单上没有包括阿富汗、中华人民共和国和越南；加拿大也被遗漏，尽管有证据表明，那里的犯罪集团越来越多地参与生产运往美国的摇头丸，而且加拿大大麻的大规模跨境贩运仍在继续。
