First of all, vape isn't smoke thus why it is called "vape". Second of all you don't get high from smoking tobacco or smoking vape. Third why do you care what someone else does with their own body? Tobacco isn't heroine, it's not going to screw you over if you do it once everyday. Also the side-effects of tobacco are often exaggerated, though I know the risks of tobacco if you over do it. I should know because my Grandmom died because of lung cancer, but then again she smoked, did pot, and was a woodstock hippie. Also it is highly implassible for someone to get cancer for just solely taking in secondhand smoke, and walking through smoke or vape isn't going to make you smell. Learn to pick your battles, and not get overworked over small things like smoking. I used to hate the smell of smoke because my family always did it, now I just don't care because I know it's something too little to get overworked over.
