And I Don't believe that a Human can achieve a large Enough Drop in Pressure to cause anywhere near a 50 ~ 200F drop in the Boiling Point of an e-liquid.
But there is a Simple way for You to Test this.
And that is just take an Empty Glass Coke Bottle and fill it about half-way with Hot Tap Water. Then do a Huge Exhale and Suck as Hard as you can on it. I mean, Really go for Broke.
If you can see Tiny Bubbles coming out of the Water, then you are Correct.
If you Can't see any Bubbles, well... , lets just cross that Bridge if we get to it.
*passes out & thuds onto the floor resoundingly for demonstrative purposes of the experiment, realizes just as he passes out he could not achieve optimal Pressure Per Square Inch (PSI) to boil water*
