There would be no consumers if there was no product in the first place. President Trump is going to wage war on cartels who are not simply providing a "product" that some people may want to snort off their tables in Beverly hills etc but who are acting outside the rules of civilised conduct in how they operate their so called "business" murdering innocent people and elected officials.
The cartels by definition are not merely outlaws but are indeed terrorist organisations due to the sheer terror they instill upon the citizenry.
President Trump is correct to use the resources available to fight against cartels instead of wasting said resources making ordinary non violent peoples lives a misery . People who smoke pot or even snort coke should have the choice to buy it from government approved sources although I personally think coke should be best only an ingredient in coca cola like in the good old days.
Cartels are vicious but most of their customers are merely fools.
