I'm not sure on international HA internal relations, but Canadian HA's have some of the more influential chapters, and some play a pretty big role in drug trade. When you bring in money, generally people look the other way.
I read about a case in the 90s where HA in London (UK) imported cocaine from Colombia with help from Canadian HA, I'm sure the Canadians still work at an international level with ties to Europe and Australia.
