Mexico's narcos have traditionally grown heroin and marijuana. They've been the primary smugglers of Colombian cocaine since the 1980s, and in the 1990s moved into meth, to satisfy that insatiable middle-american market.
But all this time, they've been overlooking a real potential cash cow (or should i say, pig).
If the narcos had any sense, they'd start exporting cochinita pibil. It's highly addictive, dirt cheap, and can be ingested in a variety of ways.
Apologies for breaking off topic, but I needed to write something to brighten my day.
