I have been smoking a little, maybe a total of 25-30 cigarettes in total, but I dont always inhale. I think I inhale perhaps 2-3 times per cigarette, and I was wondering if this was enough to give me mouth cancer or any other type of cancer. I also wanted to know how much/ how many i would have to smoke for it to become a problem because I am worried right now about getting cancer and I have decided to stop.
