Congratulations on getting off the addiction wagon. I'd certainly say "less is more" when it comes to things people put in their bodies. That said, after 20 years of smoking and switching to e-cigs myself, the most important advice I have to those interested in pursuing vaping is to use quality equipment and e-liquid. The cheap, disposable e-cigs found in many gas stations and their cheap rechargeable counterparts available online will disappoint most people. The quality control in the cheap products is nonexistent, leading to poor results in many cases.
After wasting a bunch of money on cheap crap, I listened to a few of my coworkers and bought one their mods, a ProVari v1. No, I am not being compensated by Provape; I have no association with the manufacturer, not even as a direct customer, having bought this mod from my friend. After adding a Kanger T3S tank and filling up with various tasty flavors from my local vape shop, I'm extremely happy. The difference between this and the cheap crap is absolutely night and day.
