Why do I always feel like I need to poop after smoking a cigarette?

I read about this somewhere. Apparently there's a reason for it. Nicotine increases activity in the bowel and regulates it somewhat. Hence the need to void. I do know people who had troubel in that dept when they gave up the gaspers. There was some evidence that certain bowel disorders (colitis and IBS) was less in smokers than non smokers. Bowel cancer was higher so not really a good bet though.:o:)
