As someone who works in medical research, I'm pretty sure it's possible to create a GM bacterial version of poppy's, just like we've got that for insulin, that would end the drug wars, by enabling hundreds of grams of the stuff to be produced in a single bottle that can be kept virtually anywhere (it has to be kept heated, and shaken from time to time).

Such a bottle's contents can be trivially duplicated and the whole process is essentially the same as the first steps in brewing beer.

Doing it for cocaine is simpler than doing it for insulin, which is in one university a second-year exercise. I don't think it'll be that long before this happens.
