It took a Constitutional amendment to change the status of alcohol from legal to illegal.
Drugs were never legal,
You must be kidding. Coca Cola was orginally a cocaine concoction. And legal. Morphine was legal, and it and other modes of opium were the active ingredient in many patent medicines in the later 1800's, up until the KKK 1910's.
Vin Suprynowitz in his book “Send in the Waco Killers” raised this very point - if you look back at the 1800s, both alcohol and drugs were legal. It was acknowledged in the 1910s that the FedGov did NOT have the power to control alcohol production, distribution, and consumption under the Constitution, so a constitutional amendment was needed to make it happen. But the very year that a consitutional amendment was passed to eliminate Prohibition, Congress passed laws to control the production, distrubtion, and consumption of drugs ... with no outcry that the Consitution did not allow it. After all, with the Roosevelt as President, a Congress that passed laws to prohibit a farmer from growing wheat on his own land for his own consumption, and a Supreme Court that upheld such laws, banning drugs was no big deal.
This topic is also covered in the History Channel program “Hooked: Illegal drugs and how they got that way” (or something to that effect) which I see repeated every month or so.
Or go onto the net and do some research.
