Hi, Freedom. OK, this is interesting. It could be that your smoking was actually preventing you from getting canker sores, and now that you've quit, you've lost your protection.
Awright, I know that isn't what you wanted to hear, and that may not be the case at all... or it may be... go to see your doctor about it for the straight goods.
Anyway, this is what I found on the net, and a link to the site:
"APHTHOUS ULCERS AND FEVER BLISTERS. Recurring aphthous ulcers, or canker sores, are exquisitely painful and very common, affecting 10-20% of the general population and as much as 50% of health professionals. Rather than producing or inducing this ulcerative disorder, tobacco smoking seems to prevent its occurrence or diminish its effects. Aphthae frequently begin to appear or reappear in persons who stop smoking, and almost all (96%) affected individuals are nonsmokers. Canker sores are likewise less prevalent in smokeless tobacco users than in nonusers. The reasons for this "protection" are unclear, but may be related to an increased mucosal keratinization or a reduced immune attack against the bacterial antigens thought to trigger ulcer formation."
