Smoking after running?

I know it sounds terrible lol. But I was wondering if any of you smoked after you went for a run, whether it be immediately after you get back or within an hour or 2, and if so, does it change it at all? I know that even if I don't get a runners high that when I get back from a run I still have that feel good just got done exercising feel, so does that interact with your high in anyway? Just wondering if it would change the experience because of the natural "drugs" already in your body. Any comments?
