I take it you just don't understand how important it is for cartels to keep the supply of their goods restricted so their prices can be exorbitant, nor do you understand just how long the drug cartels have been running the world. Well, before we were a nation, we had merchants joining in with the British opium trade. It was a great international corporation called the British Far East Trading Company. First they had agents beating the bushes of Africa to round up some cheap labor, and packed their empty holds for the run to the Americas for sale, where they picked up sugar, rum, cotton, furs and lumber for the run to England, where they provided the raw materials for the sweatshop factories of Liverpool. Then, loaded with cotton cloth products they sailed to India where they undersold local cotton growers and weavers, and with the help of military occupation troops forced the Indian cotton growers to grow opium, instead. In India they loaded up with opium and sailed for China, where with gunboat "diplomacy" they forced the Chinese to allow them to offload their drugs for the supply of the opium dens, and picked up tea and silk. And on back through Singapore to pick up spices and tin perhaps. . . . but everywhere they went, the left cats and drug addicts.
George Bush's ancestors were involved in the opium trade, and many of our largest and most influential banks have through all time facilitated the drug cartels by accepting deposits from them, and furnishing them cover for their business.
The war on Hemp began with the invention of nylon, and the urgent necessity of outlawing competitive rope materials.
But the place where the drug legalization folks lose my sympathy is in not recognizing that the use of drugs and other products of practically no necessary utility and significant negative health impacts, like is the case with alcohol, tobacco, and many pharmaceuticals, is something we can well afford to dispense with. The end of the British Slave Trade was accomplished with a neat slogan "No Sugar For My Tea", and "No Tea, please." and exposing the persons whose wealth was derived from the slave trade.
I agree there is no constitutional authority for the government to regulate the materials we trade or the use we make of them, but take it one step further and refuse to patronize the damned cartels, OK.
