Yes, I know. Smoking is bad, mmmmkay. I understand that inhaling the particulate smoke of ANY burning substance is putting chemicals, and particles into your lungs. I also understand that the moment anyone makes a smoking topic there are two likely distractions: 1) It's just bad, people who do it are bad, and I love telling people that I am smarter than they are. 2) Smoke weed instead, it cures everything and I love telling people that I am smarter than they are. Please don't derail this in either of those two directions. I don't need to hear #1 and I will ban for #2 (you don't want to test me). My question is this. I know of a lot of people who DO smoke cigarettes. I used to myself, a long time ago and I was able to quit. But I am seeing more and more people using e-cigarettes (or "vaping" which I guess is the hipster term for it). I am pretty up to date on the physics, medical aspects, health risks, consequences etc. for cigarette smoking. However, I am not as well-versed or up-to-speed on vaping. From what I can tell, it is an atomizer that uses a liquid (of varying compositions and flavors) and the vapor is inhaled. Does anyone have any first or secondhand knowledge of this? Anyone smoke e-cigs? What are the positives, negatives, differences, etc. If you have reviews, data, links, I would appreciate it. But I would not appreciate this topic falling victim to distractions 1 OR 2. Thanks in advance.
