The health benefits of medical marijuana are downplayed, dismissed and rejected by the government's Food and Drug Administration (FDA). In its advisory, FDA claimed that "no sound scientific studies supported medical use of marijuana for treatment in the United States."
On the other hand, in 2008 the ten largest pharmaceutical companies made a combined $276.5B in U.S. sales. To put into perspective, that is over a quarter of a trillion dollars from ten corporations.
Do you think these corporations are interested in giving up market share to anyone, much less a multi use natural remedy that anyone can grow for themselves?
