The only way to stop these large criminal enterprises is to legalize the stuff. Just like alcohol prohibition created some of the most notorious American criminals, South American drug prohibitions produce powerful criminals down there. There isn't any large crime related to South American cocoa or coffee imports. Legalize it and then spend money and make laws regulating consumption, it would greatly reduce the miser…
Even today tobacco, mostly cigarettes, is smuggled and it is legal, people hate the high taxes implemented to help cover healthcare costs. The majority of legal drug (tobacco, alcohol) users it seems are low income so it would make sense taxes are a large part of the purchase price.
It's the same for alcohol easy to make and I think if I remember hearing it correctly from high school teacher that (here in Canada) the cost of alcohol is 99% tax.
Then people would say tobacco, alcohol, and probably drugs too if they are legalized should not be taxed so high, it's never ending.
If I said I didn't care if someone killed themselves using drugs that sounds callous but if I said I cared and thought people should not be able to use meth or crack then I'm told to mind my own business.
And people are living shorter lives due to morbid obesity because they can't manage to eat a healthy diet what would happen if drugs are legalized? People balk at taxing unhealthy food I can't imagine adding legal crack into that mess. People in the US and Canada can't seem to regulate their vices, I foresee massive numbers of deaths if drugs are legalized.
