I'd like to see the response to this:
The primary industry that funded and created the campaign to outlaw cannabis in the early 20th century, is none other than the lumber industry. The industry that would be the most easily replaced by Cannabis crops. The campaign, of course, was based on serious misinformation and used Freudian style propagandistic techniques to achieve a cultural response. Many of the products and consumables produced by the lumber industry would be more effectively grown and exponentially more harvestable in the very unique cannabis crop. 1 acre of cannabis produces at minimum what 4 acres of controlled forests produce. There is absolutely no doubt that legalizing and growing cannabis crops would take a large chunk of the lumber industries market.
In years prior to cannabis' prohibition, the industry and its private and political allies banded together in creating one of the most scientifically void, terrorizing propoganda campaigns in the history of mankind. 'Reefer Madness' being the crux and epitome of such a campaign, a movie which profoundly influenced early prohibition, and a movie which even by todays standards is void of sound, empirical reasoning. Since then, the rhetoric has changed - but its still just as empty.
Heres the 1930's rhetoric, courtesy of reefer madness, it was sensationalized nonsense then, and its sensationalized nonsense now.
Keep in mind, now not even the most anti-drug campaign would try to paint cannabis as a violence inducing susbtance. With the cultures greater awareness of its effects, they realize it is nonsense, but back then - people were still ready to believe it. The lies have since then changed, but the emptiness of the rhetoric is still ever present.
Propaganda is a concerted set of messages aimed at influencing the opinions or behaviors of large numbers of people. As opposed to impartially providing information, propaganda in its most basic sense presents information in order to influence its audience. Propaganda often presents facts selectively (thus lying by omission) to encourage a particular synthesis, or gives loaded messages in order to produce an emotional rather than rational response to the information presented. The desired result is a change of the cognitive narrative of the subject in the target audience to further a political agenda. - Wiki
