A brief article by Dr. Hanauer that starts with the sentence "The evidence is clear" but sites absolutely no evidence?
The Hungarian meta analysis concludes the following:

Smoking is an important environmental factor in inflammatory bowel disease (IBD), having different effects in ulcerative colitis (UC) and Crohn’s disease (CD). A recent meta-analysis partially confirmed previous findings that smoking was found to be protective against ulcerative colitis and, after onset of the disease, might improve its course, decreasing the need for colectomy. However, smoking increases the risk of developing Crohn’s disease and worsens its course, increasing the need for steroids, immunosuppressants and re-operations. Smoking cessation aggravates ulcerative colitis and improves Crohn’s disease. Data are however, largely conflictive as well as the potential mechanisms involved in this dual relationship are still unknown. In this review article, the authors review the role of smoking in inflammatory bowel diseases.
How does that study support nicotine use("might improve its course") let alone cigarette smoking?
The evidence from which he based his conclusion on was from numerous studies done around the world dating back to 1982. Including one that he was a part of at the University of Chicago in 1994 - http://www.ncbi.nlm.nih.gov/pubmed/8170192
. As to why he didn't cite any specific studies I'm not sure. Probably because that article was written only for the Chrohns/Colitis foundation and not for peer review in a publication. It was meant for non-scientists to read.
As to your last question I'm not sure exactly what you are asking. How does the Hungarian analysis study support nictoine use? I'm not sure. It's not the be all end of of the studies done regarding cigs and colitis. None of these are. Researchers are still working on this. But the evidence at the moment is overwhelming (I'm not going to post every study. Just use google and you'll find them as did I) that something in cig's protects against colitis and instigates chrohns. If you are looking for a study that concludes with a recommendation that people take up smoking to treat UC I don't think you'll find any. The goal of the studies is just to find out what the effects are if any of smoking on IBD. And all of them seem to conclude the same.
Heres a few studies that a quick google search turned up
