Cartels wouldn't have a business selling something like marijuana post-legalization. Just about anybody can grow it almost anywhere so its natural market value is extremely low. I doubt there are a lot of gangs financing their criminal activity off of potato sales or whatever.

Extortion and kidnapping must be way less pleasant and much more difficult than dealing drugs. It's very hard to believe that they could scale up to be the same sort of revenue source.

As for the US and its supposed success, sure, it's better off than Honduras, but it still spends a fortune on law enforcement and has a massive prison population. I don't want to think of how many lives have been ruined over needless drug-related convictions. US demand and money are also what's fuelling a lot of the violence in Latin America.

I disagree. I think the cartels or some large agro businesses would set up huge farms just like tobacco farms. I'm fairly certain it's perfectly legal to grow tobacco in your backyard, but no on does because it's so much cheaper and easier to buy it from a farm.

So those people with expertise in growing it would continue to do so but out in the open in huge farms and profits would plummet to near at-cost production levels as they compete with similar large farms.
