why does vapor make me cough?

[one percenter]

Its the hot vapor hitting your throat......high temps = harsher vapor hits.......lower temps = smother vapor hits.

340-365*F gives off smooth vapor hits above that its gets harsher .....in my volcano anyway

drawing your vapor through a bong cools the vapor also...nice smooth hits

Care to elborate on the bong set up? I have an EZ Vape and am looking for a way to cool the hits down to lessen coughing. How do you hook this up? Your help would be greatly appreciated. Thanks
