The stories about users upping the amount of nicotine they consume is very true. I was a casual smoker (only a few cigs a day), and when I switched to juuling I quickly became a pod a day vaper, and was very addicted to niccotine. They really need to release differing concentrations -- while the 50mg is great for pack a day smokers, they need to release lower amounts for all the other types of smokers wishing to quit out there. The current formula has more nicotine per puff than when smoking a cigarette. I think they should get that on par, as many users with oral fixations just like to take many puffs, but may not want the nic.
However, when it came time to quit, it actually wasn't that bad. The biggest hurdle was the mental addiction to the act of juuling, but I didn't feel any withdrawals, and I didn't get quitting sickness (which I have gotten in the past when quitting directly from smoking)
