In 1939, Henry P. Anslinger started to push for the criminalization of cannabis.
It was a racially motivated act that was driven by greed, as DuPont would lose a lot of cash (plastics had just been discovered), and, it made it easier to go after blacks and hispanics, as they were the main consumers of cannabis at the time.
Therefore.........
If you don't smoke pot, or allow others to smoke if they wish, you are a domineering, greedy racist and should be shot immediately, as you're too dangerous to allow to run around society with freedom intact.
And......if you don't believe that greed is bad for this country, I would gladly direct your attention to Wall St. as of late.
