Yes, tobacco is not helpful for IBS. If you ever taken an anti-spasmodic, that blocks acetylcholine, a chemical that controls your muscles. Blocking it slows them down and slows your gut down, keeps it from causing those spasmy cramps.
Nicotine causes the release of acetylcholine (i believe), and makes muscles spasm.

That being said, I smoke... I'm trying to quit.

Depression is a killer too... nicotine is also an anti-depressant.
