Insightful posting over on Drug WarRant about pot arrests in the U.S. since the '70s:
* "We are winning this war [on drugs]." --Pres. Richard Nixon, Oct. 15, 1972
* "It is the declared policy of the United States to create a Drug-Free America by 1995." --The Anti-Drug Abuse Act of 1988, Sec. 5251-B, enacted by Congress and Pres. Ronald Reagan
Sure looks like you're winning to me, Mr. President. Obviously arrests are what matter, and the fact that availability has remained more or less unchanged is surely just a trivial matter of inflation or something similar. Nothing to worry about - drug situation is firmly under control.
There's also another conjecture in another post about
how Drug Czar John Walters is really a drug lord that I found rather amusing.
