The war on drugs has also been a war on disfavored groups, particularly blacks. From Alfred McCoy at consortiumnews.com:
Fifty years ago, on June 17, 1971, President Richard Nixon stood before the White House press corps, staffers at his side, to announce “a new, all-out offensive” against drug abuse, which he denounced as “America’s public enemy number one.” He called on Congress to contribute $350 million for a worldwide attack on “the sources of supply.” The first battle in this new drug war would be fought in South Vietnam where, Nixon said, “a number of young Americans have become addicts as they serve abroad.”
While the president was declaring his war on drugs, I was stepping off a trans-Pacific flight into the searing tropical heat of Saigon, the South Vietnamese capital, to report on the sources of supply for the drug abuse that was indeed sweeping through the ranks of American soldiers fighting this country’s war in Vietnam.
As I would soon discover, the situation was far worse than anything Nixon could have conveyed in his sparse words. Heroin vials littered the floors of Army barracks. Units legendary for their heroism in World War II like the 82nd Airborne were now known as the “jumping junkies.” A later survey found that more than a third of all GIs fighting the Vietnam War “commonly used” heroin. Desperate to defeat this invisible enemy, the White House was now about to throw millions of dollars at this overseas drug war, funding mass urinalysis screening for every homeward-bound GI and mandatory treatment for any who tested positive for drugs.
