Prohibition is not an archaic concept. Though permanently tied to gangster stories from the 1930s, it happens every single day in this country. Fair dos, alcohol is legal enough - but many other things that people choose to put in their bodies are not. It has been thirty years since Reagan declared his war on drugs. To borrow a quip, “the people on drugs are winning”. Perhaps Obama has heard it.
That same country now offers legal marijuana for recreational purposes in some of its states. As soon as the dollar value is properly understood, I’m sure we’ll see more states going green.
