The entrepreneurs of the drug trade usually keep a few steps ahead of the gumshoes. Traffickers have it pretty easy. A mere thirteen truckloads of cocaine can meet today's demand at current prices. Law enforcement admits that if it could intercept five percent of supply, it would be phenomenal. So much for the logic of interdiction.
Drug prices keep falling and quality keeps rising.
But results don't matter much in drug politics. Demand induces supply. The profit mechanism ensures it. The paying customer is king. The fundamental truth is that government has lost its drug war.
