I see no problems with it, I also grew up with a mom who chain smoked 24/7 including while she was pregnant with me and my sisters and we all turned out fine. Oddly enough none of us ever smoked. Yes I vape but I never smoked, I chewed tobacco for almost 20 years. I only started to do that as a way to cut weight for wrestling and got addicted to it. All of my siblings always though smoking was disgusting. In fact I remember a number of times I threw out packs of my mom's cigarettes as a way to tell her to quit. She finally quit about 10 years ago cold turkey. I personally would much rather have my kid pick up vaping rather than smoking.
