The cartels, of course, are adapting to the new reality. Seizure data appears to indicate that with marijuana profits tumbling, they're switching over to heroin and meth. This is a really interesting development. There's always been this "gateway drug" argument around pot: once people start with marijuana, they'll move onto the harder stuff.
