Since the 1960s and the emergence of the New Left, and the introduction of the Frankfurt School and 60s post modernism into academia, there has been a widespread belief amongst a large segment of the population that everything traditional is wrong. A social stigma is merely ignorance, that which is seen as bad is actually good, traditions are wrong. All of these things need to be overturned for the enlightenment. Since society deemed marijuana bad, it is therefore good. As those people who were went through that indoctrination in the 60s as students got older, they got into power. They took power in universities. By the 90s they were pushing all of the ideas as the status quo. Students in the 90s then took those ideas, and when they got into power in Media, they pushed those ideas into all movies and tv.
