Comment by AnthonyMouse

The Wartime Prohibition Act was passed during the drawdown from World War I and the basis for upholding it was the wartime powers of Congress because of a scarcity of grain from the war.

The last Congressionally declared war was World War II, so if that was supposed to be the constitutional basis for the Controlled Substances Act, there would seem to be the obvious problems that the war was generations ago and nobody is diverting scanty wheat from the food markets to make MDMA.
