when was hemp made illegal in the united states
Legal history of cannabis in the United States The decision of the United States Congress to pass the Marihuana Tax Act of 1937 was based on poorly attended hearings and reports based on questionable studies.[41][42] In 1936 the Federal Bureau of Narcotics (FBN) noticed an increase of reports of people smoking marijuana, which further increased in 1937. The Bureau drafted a legislative plan for Congress seeking a new law, and the head of the FBN, Harry J. Anslinger, ran a campaign against marijuana.[43][44] Newspaper mogul William Randolph Hearst's empire of newspapers used the "yellow journalism" pioneered by Hearst to demonize the cannabis plant and spread a public perception that there were connections between cannabis and violent crime.[45] Several scholars argue that the goal was to destroy the hemp industry,[46][47][48] largely as an effort of Hearst, Andrew Mellon and the Du Pont family.[46][48] They argue that with the invention of the decorticator hemp became a very cheap substitute for the wood pulp that was used in the newspaper industry.[46][49] However, Hearst newspapers owed large debts to Canadian suppliers of paper, who used wood as raw material. If an alternative raw material for paper had emerged, it would have lowered the price of the paper needed to print Hearst's many newspapersâ€”a positive thing for Hearst.[50][51] Moreover, by the year 1916 there were at least five "machine brakes" for hemp[52] and it is unlikely that in 1930s hemp became a new threat for newspapers owners.
Lead-based paint in the United States Congress banned the use of lead-based paint in 1971,[3] and the Consumer Product Safety Commission followed with implementing regulations, effective in 1978.[4] Additional regulations regarding lead abatement, testing and related issues have been issued by the Environmental Protection Agency (EPA).
