Future generations will look back at this time in history and shake their heads. We are the generation that put a man on the moon and then pissed away that start to the stars. This will be known as the time of constant war- war on drugs, war on terror,war on education..., all these wars formented in order to make bigger and bigger piles of money and to fight for control. It will also be seen as a time of really big stupid things like GMO foods with terminator tech built in. Stupid greedy people came up with that one. One of the things they will really shake their heads at is the fact that we outlawed and tried to irradicate the most useful plant on the planet. How does one go about outlawing a natural plant? You do it by wasting millions of lives and billions , if not trillions of dollars tracking down, jailing and processing (non)criminals through over stressed courts. People in the future will ask simple questions like "Why Hemp?" and then dig in to the discusting racist laws passed in the 1930's to see just how sick and passive the United States was then and by default see how "Big Brother" forced his warpped ideas on the rest of the world.
A breath of fresh air in the form of a vapour. They will also see how at the end of all the maddness many people rallied together to get the laws changed. It was also a time of innovations when it came to the delivery of Cannabis's medicinal properties, in the form of a modern day hookah called a vapourizer, came to be. Post- modern man will understand on an intuitive level that a plant multiplies on a logarithmic Scale and the thugs hired to rip them from the ground is a linear scale. Any government does not have the rescources to do that. Post - modern man will also be closer to nature so they will understand that all it takes is just one bird, eating one seed and then transporting that seed to another area, to start the growth cycle all over again. How can you fight against that? Insanity.
Post-modern man will most likely conclude that the poisons we injected in our environment drove us to be insane and formentors of war, any war ( even if it makes no sense).
