I don't know maybe because it's 3 am or because I'm really tired but can't sleep.. but I have a weird question. I've seen in threads people talking about how to properly taste their vape to get a full sense of the flavor.. 'picking up nuances' one person referred to it by exhaling through the nose. I know part of taste comes from sense of smell... but I don't get it.. All I get out of it is an urge to sneeze. So what's the deal with this, does it really make a difference?
