Dear Prudence,
Our 19-year-old son is home for a break before beginning his sophomore year of college. His vaping device fell out of his pocket while we were watching TV. All of his money comes from us. He had a “normal” freshman year, with perhaps a bit too much entertainment at the beginning, and grades that started out badly and improved through the year. I’ve discussed the dangers of e-cigarettes with him. Since I essentially paid for this stupid device, can I take it away from him? I know that won’t do any good—he can just buy another. So what do I do now?
