I've been a smoker for 19-20yrs and finally quit smoking using a tececig "rookie mistake" but at least I'm not smoking anymore. I have found that this "rodeo" called vaping is a very absorbing activity, not that there is anything wrong with that. I am still learning about vaping techniques, mods, tanks, ect... I thought hmmmm e cig easy fool proof then I dig deeper and HOLY CRAP new info around every corner.
