The US is experiencing the worst drug addiction crisis in decades. Heroin addiction is out of control. Whole towns are being wiped out by heroin. I have students who are escaping such towns and they tell of terrible things.
94% of all the heroin in the US comes from Mexico. In Mexico, cartels are slaughtering each other and the innocent civilians for access to the distribution areas of the drug in the US. Drugs cross the border with ease.
The problem is that there is no evidence that clamping down the border will help. When there is such a huge demand, there’s no likelihood that it will go unmet.
In the last years of the USSR, an attempt was made to battle alcoholism. But when the access to alcohol was limited, not a single addict got cured. Those of the lower social classes drank cologne and sniffed glue. Those higher up switched to hard drugs. The anti-alcoholism campaign turned out to be part of a concerted effort to promote drug addiction in the USSR.
Addicts will find their drug and the drug will find its way to them. Drug addiction rates can only be addressed from the consumption side. Treating people and creating conditions that will prevent new addicts from appearing will defeat cartels. Borders never did and never will. I wish this weren’t true. I hate drugs and I’d support any kind of border security that could limit the flow of heroin into this country. But there is no evidence that it ever helped.
