I wholeheartedly understand that "nootropic" is at best a vernacular terminology and not a scientific term, but one thing I do not quite understand is why caffeine is considered a "nootropic" while amphetamines are commonly related to as "tweaked drugs" and other derogatory terms. The positive cognitive enhancing effects of amphetamines have been proven across the board for a wide range of conditions and this has been known for more than 100 years. Could this whole linguistic controversy be purely contributed to the fact that propaganda even seeps through the internet and the people who use it? Who knows?
