Comfortably numb!
Bottom line here, lungs were meant to breath oxygen <--- period. Anything else is only inviting trouble and, sorry no, one does not have to be a rocket scientist to figure it out. I've been a vaper since 2010. I smoked for 33yrs. Vaping is merely a "safer" alternative to smoking (for those who can't quit). Read not a safe way. Combusting anything and breathing is not a good thing.
