As for as the drugs go it will not even slow the drugs down. As long as their is a huge market for them they will be coming into or made in this country,
Donald Trump tied the heroin epidemic gripping suburban white communities to the issue central to the campaign: border security and illegal immigration.
We’ve all heard of poppy fields blooming in Afghanistan, but is Trump right that heroin is entering the United States largely through the southern border?
Yes. Even though Southwest Asia supplies heroin to most of the rest of the world, nearly all of the heroin available in the United States comes from Mexico and South America.
Trump is right: Heroin is coming in through southern border
But what does that have to do with building a wall. Most of the drugs that come across the border do so by planes, motor vehicles and boats which will continue with or without a wall.
What does that piece say? It says most of our heroine comes across that southern border. No, it isn't flown from Mexico, it doesn't come on a boat, and it's not coming from customs. It's coming from a wall-less border and that needs to be stopped. If they can get it here other ways, then it will be a hell of a lot harder which means they would have to charge more money, and likely more people getting busted for it.
Nope:
The majority of illegal drugs entering the United States enter in an assortment of vehicles, with drugs hidden in secret compartments in door panels or the roof, gas tanks, tires and even engines.
Cargo trains, tractor-trailers and passenger buses have been used to move illegal drugs. Trucks and trains carrying fresh produce such as watermelons, limes and other fruits bring in millions of pounds of illegal drugs.
The next most common method of bringing drugs into the US is cargo ships and planes.
The least likely method for bring drug enter into the US is individuals carrying them across the border. One semi properly outfitted can bring in more drugs than 50 backpackers. One ship cargo container can bring in more drugs than a 700 backpackers. It's a matter of economic. Meeting the demand for drugs in the US with back packers coming across the border would be both impossible and far more expense than other methods. This is why building walls or other barriers along the border would have very little impact on drug importation.
The profit margin on illegal drugs is so high, you could close the entire southern border and all it would do is raise the price of drugs to cover the added cost of alternative transportation.
