I am 21 and have not really ever had a serious problem with smoking.. I tend to have the urge though to smoke when surrounded by other smokers ( club, Fiance, group of co-workers, etc) and i just bought a zero nicotine Blu Cig.. I think my addiction if i can call it that is the oral fixation while surrounded by other smokers.. I was curious if the zero nicotine carts are really zero nicotine and am i getting any other negative side effects from vaping on these E-Cigs (not that i will stop because surely this is a better option then analogs) but just wanted to know if i am harming anything else in the process. Thank you for your responses and please just informative post don't need to hear i shouldn't be smoking them if i am not addicted to nicotine.. i know that for one but i would rather have this to pull out when i am around other smokers then to take out a analog every once in a while. Thanks again!
