I agree, it's the government's fault. Nobody knew that drugs which got you high were bad for you, except for everyone over the last fifty years.
Think it's a form of "bible brain". Were you raised in a religious household? When you're raised to believe in something like god, where you can hear about crazy magic and ask your parents if it's true and they say "of course it is!!", versus being told "ah it's just a story", then it trains the brain for conflict with a world that doesn't exist. Also why right leaning people are so infuriated by "fake news", because the idea that something which may not be true, is totally confusing and infuriating from the gullibility their parents have fostered. Whereas others who were raised to put very little stock into things other people say, fake news is nothing.
