About cartels and/or drug trafficking in Latin America

Hi there.

As you can probably guess, I'm mexican. Here, we have a very serious problem with cartels, as I'm sure most of you know. I also understand this is a serious issue in places like Brazil, Ecuador, Venezuela, etc.

What I'm curious about is, how big is the problem in other countries we often don't hear about? Like, for example, Dominican Republic, Cuba, Chile, Argentina, Paraguay, etc? Are we not hearing about it because it's not that big of an issue, or is it because it gets buried under all the Mexico/Venezuela content?

Thanks for reading, good night.
