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.
