This is a very good documentary. It is not done with bias, and results are compared side by side as to the effects of smoking, vaping, never smoked or vaped. It is very nice to see these studies done in a "this is what happens when you vape, but this is what happens when you smoke" format. I put this in the new vapers section since these are interesting facts new vapers should know. Especially those who are either quitting smoking or never smoked but started vaping for their own reasons. Enjoy!
