Hey guys. I know vapor is safer than smoke so I was wondering about second hand vapor around my son who is 2. In the car? Windows up? Down? In the house? Etc. Please don't tell me that vapor is harmless in every way imaginable. It is not natural, therefore in my opinion it is not 100% "safe" as there are different chemicals used for consistency and flavors and many, many different brands of e liquids made in many, many different labs or even in a local shop's back room. Should I have concerns? I keep the liquid and vapor away from him of course but still curious. Thanks!
