I live alone in a home I own. Recently invited by 10 years younger brother to live with me while working toward a pilot's license. He vapes daily and drinks. I do neither (religious).
He asked if he could vape in the house. He said "It's only nicotine, and it calms me down when I sleep," not as an excuse, but as an explanation. Do I allow vaping in the home, when I would never allow smoking? I don't mind the alcohol.
