Smoke Em If You Got Em!

So I was faced with a dilemma this evening as I went to meet a friend for coffee. A woman was walking down Park Ave and dropped her pack of cigarettes. Now I started to tell her that she dropped something, then I realized they were cigarettes and hesitated. I thought for a second that I would be doing her a favor if I just let them lay on the ground. However, I realized quickly that she would just go and buy more so I picked them up for her and handed them over. So, is it a good thing that I gave them back or a bad thing that I am contributing to her eminent lung disease. Hell, I just wanted to grab a vanilla latte, I didn't think the trip would end up as a point of serious reflection?
