This is just a guess but I think that the song means just don't believe what you are told actually take the time to understand and get facts, here is an example the government says that weed is bad they say that it can make you do stupid things like jump off buildings but if you ask a doctor that won't lie to you the only thing that is bad about is you are breathing in something that is burning anything like that can be bad. But yea. Lol.
