I was a pack a day cigarette smoker for 6 years before switching to vaping. Since then I have moved from small ego styled vaporizers to mods purchasing my juices in various flavors at 12 mg nic. The ability to choose my own juices was crucial to my success in quitting. I have been smoke free now for 1 and a half years . My health is better and even my doctor is in full support. Thanks to vaping I am no longer a slave to a filthy stinky habit.
