Here is the link to the NY Times article, US DRONES FIGHT MEXICAN DRUG TRADE in today's paper. It details what probably is only the surface of US involvement. If the US thinks it is just the head honchos that make up the problem and the drugs are the only product of concern they don't know much yet except from a fairly ignorant US point of view. The ignorance is, of course, born of selfishness: the US refusal to consider its own habits are what usually are mentioned in this context. But stuff like unfair trade practices (extremely unfair) are among many others. And I guess the whole notion that the US is doing all this training is really kind of repulsive.
