I wonder how many people even Know how much hemp was raised as a commercial crop in America. Big oil and pharmaceutical companies went to D.C.and lobbied against it ,or it would still be a major industry. And the plastics that pollute our lands and waters just wouldn't be near the issue that they are.
Ford recognized the utility of the hemp plant. He constructed a car of resin stiffened hemp fiber, and even ran the car on ethanol made from hemp. Ford knew that hemp could produce vast economic resources if widely cultivated.
Ford's optimistic appraisal of cellulose and crop based ethyl alcohol fuel can be read in several ways. First, it can be seen as an oblique jab at a competitor. General Motors had come to considerable grief that summer of 1925 over another octane boosting fuel called tetra-ethyl lead, and government officials had been quietly in touch with Ford engineers about alternatives to leaded gasoline additives. Secondly, by 1925 the American farms that Ford loved were facing an economic crisis that would later intensify with the depression. ( How did that happen? We had the Federal Reserve watching over the economy. )Although the causes of the crisis were complex, one possible solution was seen in creating new markets for farm products. With Ford's financial and political backing, the idea of opening up industrial markets for farmers would be translated into a broad movement for scientific research in agriculture that would be labelled "Farm Chemurgy."
America could be so different, socially, economically, politically,,
But, corruption drove the legislation.
Maybe the pharmaceutical industry wasn't involved.
This campaign of lies, as well as other evidence, have led many to believe there may have been a hidden agenda behind Marijuana Prohibition.
Shortly before marijuana was banned by The Marijuana Tax Act of 1937, new technologies were developed that made hemp a potential competitor with the newly-founded synthetic fiber and plastics industries. Hemp's potential for producing paper also posed a threat to the timber industry (see New Billion-Dollar Crop). Evidence suggests that commercial interests having much to lose from hemp competition helped propagate reefer madness hysteria, and used their influence to lobby for Marijuana Prohibition. It is not known for certain if special interests conspired to destroy the hemp industry via Marijuana Prohibition, but enough evidence exists to raise the possibility.
After Alcohol Prohibition ended in 1933, funding for the Federal Bureau of Narcotics (now the Drug Enforcement Administration) was reduced. The FBN's own director, Harry J. Anslinger, then became a leading advocate of Marijuana Prohibition. In 1937 Anslinger testified before Congress in favor of Marijuana Prohibition by saying: "Marijuana is the most violence causing drug in the history of mankind." "Most marijuana smokers are Negroes, Hispanics, Filipinos and entertainers. Their Satanic music, jazz and swing, result from marijuana usage. This marijuana causes white women to seek sexual relations with Negroes." Marijuana Prohibition is founded on lies and rooted in racism, prejudice, and ignorance. Just as politicians believed Harry J. Anslinger to be a marijuana expert in 1937, many people still believe law enforcement officials are marijuana experts. In reality, law enforcement officials have no expert knowledge of marijuana's medical or health effects, but they do represent an industry that receives billions of tax dollars to enforce Marijuana Prohibition.
Before the government began promoting reefer madness hysteria during the 1930s, the word marijuana was a Mexican word that was totally absent from the American vocabulary. In the 1930s, Americans knew that hemp was a common, useful, and harmless crop. It is extremely unlikely anyone would have believed hemp was dangerous, or would have believed stories of hemp madness. Thus, the words marijuana and reefer were substituted
