Although APEC has been including drug trafficking inside its human security agenda, I haven't heard of any researcher on human security dealing with this hot issue. Besides, if it is difficult to do so in the countries where the problem is a daily reality, much more here in Japan where a pop star with milligrams of a forbidden substance has been in the news for months.
Anyway, in what I personally believe would be the better possible human-security outcome, the argument seems to be is leaning towards some form of decriminalization. Much has been heard about U.S. administration stance in this respect, but there are many other changes going on around the globe. If you want to read a little bit more about the trend, here are some links:

It seems that some of the contents from the Economist are going to be blocked after some time... Hurry up!
