Hello! I'm pretty new to vaping and I keep it simple with a Caliburn pod system. I've used two other kinds, some e-cigarette in 2014 I can't remember the name of and a juul, but the Caliburn has been super helpful for me staying off the cigs after I returned to them (quit the pack and a half a day habit years ago but I've turned to cigs in times of stress, getting back up to about half a pack a day before trying to quit again). As a health professional, I care a lot about harm reduction and think vaping is a very effective method of it for former smokers.
