Coffee is a diuretic breakfast, the cigarette is simply a side dish to your morning entree.

There have been studies done comparing Coffee, an equal volume of water, and an equal volume of water spiked with a coffee’s worth of caffeine, and found that the urge to use the bathroom is more closely linked to the volume than to the caffeine content. I’ll have to see if I can find that article again.

Nicotine from cigarettes is a stimulant of the “Nicotinic Acetylcholine Receptors” These receptors can do a lot of different things depending on where in the body they are located. The ones in the smooth muscle of your bowls respond to nicotine by telling the muscle to squeeze.

Caffeine and nicotine are diuretics, and this means they will trigger your body to release a lot of water (like what happens when you have diarrhea).

Caffeine and nicotine are stimulants. One of the things they stimulate is peristalsis, the rhythmic muscle contractions which propel the contents of your digestive tract.

This tends to make you need to poop sooner rather than later.
