Or why not just have the vaporizer deliver the vape directly into the the hot water stream. This means that no mouth delivery device is necessary.
Inhalation would come from passively inhaling the steam and vape mixture.
As an aside, I wonder if I throw
e-liquid on the hot 'coals' of a sauna it would give me a nic fix.
I'd donate $0.010000 to this kickstarter.
