Cannabis 100 Year "Smear Campaign" cannot be sustained here in the information age. People are learning the truth by the thousands and once it is excepted as medicine by society, next will come many revolutions in other industries - textiles, foods, oils, Hemp Brick construction = AMAZING! btw), and the list goes on and on. The Cannabis plant can provide almost everything humans need for basic survival and the rich who would be put out of business if.. will fight it to the death. They need to continue using fossil fuels, chemicals and toxins in things like medicines and paper etc... but the reality is they are trying to create patent-able products that simply do what Cannabis does naturally, safely and with no dangerous side affects (and is easily available to anyone who can shove a seed in the ground).
Saw a medical conference a while back where a scientist stood up and stated that they had been trying to kill test animals with Cannabis and they concluded that the only way was to drop a brick of cannabis on the animals head... It was funny but he was very serious about the point he was making.
