Ignorant or not, they're oblivious to the information that has just recently come out. I'd hate to call them ignorant for never being told the truth. It's only been 16 years since they discovered that our Brains are equipped to smoke pot, and they've only known Melatonin has existed for about 20 years, and then it took them several to find out about Pot and it's ability to promote Melatonin in the Pineal of the Brain.
