1920-1970: Oil Barons Rockefeller, Standard Oil, and Rothschild of Shell, etc., realized the possibilities of Henry Ford’s vision of cheap methanol fuel, so they kept oil prices at between one dollar and four dollars a barrel (almost 42 gallons in a barrel), so that no other energy source could compete with it, until 1970, after all competition was erased, when then price of oil jumped to almost $40/barrol over the next 10 years.

1930s: Following action by the Federal Bureau of Narcotics and a campaign by William Randolph Hearst, propaganda is created against hemp from companies with vested interest in the new petroleum-based synthetic textiles. Even though hemp reinvented itself, thanks to new technology that eased processing and expanded its use, the timber (Hearst) and oil interests (Dupont, Anslinger, Mellon) crushed competition from plant-based cellulose by demonizing marijuana, and paralleling its use to Mexican immigrants and later Black jazz musicians. The effects of marijuana are demonized with such movies as “Marijuana: assassin of youth,” Devil’s weed,” and “Reefer Madness.” Throughout this assault hemp’s link to marijuana is exaggerated.

1941-1945: Hemp for Victory
During World War II, Japan cut off our supplies of vital hemp and coarse fibers. The hemp was needed for making, among other things, rope, webbing, and canvas, to be used on navy ships. So a program was started to grow Hemp for military use under the banner of “Hemp For Victory”. After the war, licenses were subsequently revoked; at a similar time to the last hemp crops being grown in the U.K. The U. S. Department of Agriculture released an educational film called “Hemp for Victory”, which showed farmers how to grow and harvest industrial hemp. Hemp harvesting machinery was made available at low or no cost. From 1942 to 1945, farmers who agreed to grow hemp were waived from serving in the military, along with their sons; that’s how vitally important hemp was to America during World War II. The fields of hemp were termed victory gardens.
1942: Patriotic farmers plant 36,000 acres of seed hemp, an increase of several thousand percent from the previous year.
1943: Both the US and German governments urge their patriotic farmers to grow hemp for the war effort. The US shows farmers a short film – ‘Hemp for Victory’ which the government later pretends never existed.
