Smoking isn't good for anyone. The case against it is quite clear and strong. however, it seems to have a positive and incontrovertible benefit in my particular case. My crohns is very atypical... it spread so fast, and so completely, that doctors initially thought it was UC. With it came lots of bleeding... And nothing the doctors did stemmed the loss of blood I was experiencing. Then, some older patients I shared a ward with told me that if I started smoking, the bleeding would stop. I didn't believe them at first, so I started to ask the myriad of doctors I was seeing if there was any truth to it. At first, I got the same response... smoking is a no no, and it negatively affects crohns. But then, I found one doctor who reluctantly admitted it was, way back in the old days, the most common method of treating UC... and, shortly thereafter, another doctor told me essentially the same thing. But, it was for UC, not CC or CD. Why the difference I don't know. So, I started smoking, and the bleeding ceased almost immediately, and I also noticed that it had amazinng powers to ease cramping. So, I'd found a method to lessen my symptoms, but at what cost? Smoking is definitely carcinogenic, no doubt at all about it. Anyway, fast forward... I'd been on LDN treatment for 1/2 a year and was virtually symptom free... and that led me to entertain thoughts of giving up smoking. I went to a sponsored stop smoking program, but when they learned of my history with IBD, they cautioned me that it might cause me to relapse. My GI was concerned too, but we decided that it was worth the risk, bearing in mind I'd be using NRT, Nicotine Replacement Therapy. If the nicotine was causing the allievement of symptoms, then the NRT should allow me to stop smoking without issue. For whatever reason, it didn't.
Within 5 weeks of coming off tobacco, my bleeding resumed and escalated like wildfire.
I resumed smoking, and the bleeding stopped. However, my red count dropped so low it took 11 months to get back to normal. There are literally 100's of ingredients in tobacco other than nicotine, almost all of them dangerous to one extent or another, and I don't know which one (or combo thereof) contains the magic bullet for me, but it does.
I still plan on quitting in the future, but only at such a time as when I can afford to risk possible long term disability. Yes, smoking is a known carcinogen, but it works for me, and when you get right down to it, many of the drugs prescribed to treat IBD are too.
