The study also found that quitting smoking did not worsen the course of the disease in UC patients, confirming that the harm caused by smoking far outweighs any possible benefits. The study, “The impact of smoking and smoking cessation on disease outcomes in ulcerative colitis: a nationwide population‐based study,” was published in the journal Alimentary Pharmacology and Therapeutics. A previous study showed that tobacco smoke exposure was associated with approximately half the risk of developing UC.
