It's pretty obvious that they have an agenda against this plant.. and actually, I think they might actually have more of an agenda against hemp than marijuana because it has so many uses. Ever read The Emperor Wears No Clothes by Jack Herer?

Here's an excerpt:

In the mid-1930s, when the new mechanical hemp fiber stripping machines and machines to conserve hemp's high-cellulose pulp finally became state-of-the-art, available and affordable, the enormous timber acreage and businesses of the Hearst Paper Manufacturing Division, Kimberly Clark (USA), St. Regis - and virtually all other timber, paper and large newspaper holding companies - stood to lose billions of dollars and perhaps go bankrupt.

Coincidentally, in 1937, DuPont had just patented processes for making plastics from oil and coal, as well as a new sulfate/sulfite process for making paper from wood pulp. According to DuPont's own corporate records and historians,* these processes accounted for over 80% of all the company's railroad carloadings over the next 60 years into the 1990s.

*Author's research and communications with DuPont, 1985-1996.

If hemp had not been made illegal, 80% of DuPont's business would never have materialized and the great majority of the pollution which has poisoned our Northwestern and Southeastern rivers would not have occurred.

In an open marketplace, hemp would have saved the majority of America's vital family farms and would probably have boosted their numbers, despite the Great Depression of the 1930s.

But competing against environmentally-sane hemp paper and natural plastic technology would have jeopardized the lucrative financial schemes of Hearst, DuPont and DuPont's chief financial backer, Andrew Mellon of the Mellon Bank of Pittsburgh.
