I can tell you from anecdotal evidence of my own that I bought a high end american manufactured vape about 5 or 6 years ago. Everything cost around 120 to get shipped to me. I spent about 20 dollars on e juice every 3 weeks to a month. My lung health had improved signifcantly, rarely get a couch, and am revolted by the smell of cigarettes now. Once I started with the vape, I never even thought about smoking cigarettes again. I'm currently on the 6mg of nicotine level e juice. I smoked up to a pack of day for 15 years before that at 4 to 10 dollars a pack. I still find it amusing when certain hipsters who care what people think make fun of people who vape. Imagine being so worried about what others think, but you still hate on others for making themselves healthier.
