Does cigarette smoking increase the chance of diabetes?

Not Exactly. It does make diabetes harder to treat. I know of no demonstrated proof of cause & effect (smoking being a direct cause of diabetes) but it certainly can cause someone to need more medication or even Insulin when they could control the diabetes other ways. It is not good for dibetics to smoke. If you need help, you md or dentist can help you devise a plan to stop smoking if you are ready.
