I had given up smoking and was off cigarettes for a long time. One day aI suddenly got the urg tostart smoking and I had one cigarette. One led to another and so on. Now i have been smoking one odd cigarette a day and at times up to 4, but no more than that. How harmful willit be to smoke jsut about 3-4 cigarettes a day? Is it as bad as smoking a pack of 10 or it really will not be that harmful. The body must be having some self cleansing mechanism too. Excess of everything is bad but inmoderation is it ok?
