Not long ago, just a few decades back, anti marijuana propaganda movies were a required part of students education. The propaganda films were about bunch of nonsenses about marijuana that the students had to believe to. There are rumors around that Uncle Sam payed for those anti marijuana propaganda movies to fright American people, make them to believe that the cannabis will destroy their families, make thefts and drug addicts from their children. Which is complete opposite to what has been proven in the past few years. It has been scientifically proved and tested on millions of people that marijuana is a natural medical treatment for a lot of sicknesses. If you watch at least one of those movies now, you will crack out, because they look more like a silly comedy then anti-cannabis propaganda movies.
Just to prove our words, check this few movies out.
