Expensive is a subjective term. Perhaps I should have said "can be". My car is no hot rod but it costs over $500 per month to own and operate. To me that is so expensive I want to ride my bike to work (not feasible considering my 22 mile commute). I'm no cloud chaser either but I was dropping $120 for 2 people on liquid (before DIY). Think about somebody who didn't already have $200 or so carved out of their budget for tobacco. If I didn't want the nic fix, enjoy the sensation of the inhale and visible exhale, and like vaping as a hobby, I'd say dude that's as much as my cell phone bill, nvm. Too many variables to consider. Friend should be warned about the potential expense.
