The absurd drug war originated in the US
A war of human societies against themselves 

Theodore Roosevelt appointed Dr. Hamilton Wright (1908) as the first United States Opium Commissioner in 1908.
In 1909, Wright attended the International Opium Commission in Shanghai as the American delegates. He was accompanied by Charles Henry Brent, the Bishop Bishop
On March 12, 1911, Dr. Wright said in a New York Times article: "Opium, the most pernicious drug known to mankind, is surrounded, in this country, with much less guarantees than any other nation in Europe. "
Wright further stated that "it has been authoritatively asserted that cocaine is often the direct incentive for the crime of rape of blacks in the South and other parts of the country,", He did not provide any proof of his claim.
Wright also said that "one of the most unfortunate phases of opium smoking in this country is the large number of women who have been involved and lived as concubines or cohabiting with Chinese in the Chinese neighborhoods of our different cities."
The culmination of the repressive process was the Harrison Anti-Narcotics legislation (1914) which consisted of three projects of the US Chamber. imposing restrictions on the availability and consumption of the psychoactive opium drug.
The editors were based on fears that there were "drugged blacks, sexual maniacs" and made references to blacks under the influence of drugs murdering whites, degenerate Mexicans smoking marijuana, and "Chinese" seducing white women with drugs. [ 19] [20] Dr. Hamilton Wright declared at a Harrison Law hearing "drugs make blacks uncontrollable, gave them superhuman powers and caused them to rebel against white authority." Dr. Christopher Koch of the Pennsylvania State Pharmacy Board said that "Most attacks on white women in the south are the direct result of blacks freaking out of cocaine." [6]
Before the law was passed, on February 8, 1914, The New York Times published an article by Edward Huntington Williams entitled "Black demons drugged with cocaine" and then said "they are the new threat in the South: Murder and the madness is growing among black low-class blacks "also reported that in the South the sheriffs had increased the caliber of their weapons to .32 to .38 to bring down blacks under the effect of cocaine.
Despite the extreme racialization of the issue that took place in the previous approval of the Law, contemporary research on the subject indicates that black Americans used cocaine and opium at much lower rates than white Americans.
Later, on January 17, 1920, Amendment XVIII to the United States Constitution that established “the Prohibition” where alcohol was banned. This "prohibition" lasted for 13 years, Finally, due to its thunderous failure creating “mafias” and criminal organizations the law was repealed on December 5, 1933.
In 1937, marijuana was banned through the Marijuana Tax Act and years later, international pressure would be internationally exerted until the rest of the world was forced to embark on an absurd and cruel prohibitionist crusade that has caused and continues to cause millions of victims for several decades
