Interesting connection I have made here in my own research. I would answer your question with a "yes" tobacco helps. I am a laymen, not md, more eastern medicine, spiritual, non religion. I don't believe in what others tell me, I find out for myself. so check it out for yourself...
Nicotine is an alkaloid. It is also a night shade (meaning - acid lover). While I was looking at Loperamide over the counter - OTC (Imodium) as a possible fix for my IBS symptoms to settle gut spasms I found that Loperamide the active ingredient is an opioid drug similer to opiate drugs id est / I.E. Morphine, Coedine, ect... and it is physically adictive. How this is OTC is bizarre, it is illegal in Pakistan leading Poppy producer world wide, go figure. Now, we know Loperamide is opiod drug. We also know it is a derivative of piperidine. If you look up piperidine you will find that tobacco or nicotine falls under this category compound type, as well as black pepper, poison hemlock, egg plant, ect... As a side note it is also interesting to know these all are night shade plants. Night shades tend to cause acid reflux in many people who have GERD type issues. Now look up Helicobacter pylori and you will find this is a bacteria that is found in many IBS sufferers in high levels in the large and small intestines as well as in the stomach. When acid levels are depleted or removed all together from either a H-2 reducer like Pepcid or Zantac, or a proton pump inhibitor like Prilosec or Prevacid this bacteria is not killed off by stomach acid and therefore thrives causing little critters to eat and digest your food before you can, drop fecal matter into your gut, and methane with that all of which will cause gas.
This is all theory I must remind. But let me ask you this; when smokers stop smoking, what do they replace smoking with, and what happens? Eating, weight gain. When smokers still smoked they would always have a smoke after eating and most would say "it helps digestion", most smokers are thin.
This has been a bunch of rambling by a none tobacco user who instead uses a nigh shade plant our species has used since before recorded history "tree of knowledge of good and evil" which tends to help my symptoms a great deal, why do you think cancer patients use it for nausea.
One thing remains clear. Instinct is natural. Pharma is manufactured and controlled. Humans purpose in life is not to be controlled. Inhale exhale know freedom and choice. Ask John Galt, he will tell you.
