After Smoking hookah, I really liked it. I am NOT a smoker but i do like the flavors that is has and i like blowing out the vapors. I did a little homework and i saw that some E-cigs had flavors that did NOT contain any nicotine. I know its still not 100 percent safe and there are always some risks when inhaling anything but If it does not have nicotine and it does not contain tobacco then all i am really smoking is flavored water vapor right? I would like to know more about it. and if it is "safe". thanks.
