1 cigarette is very different to two cigarettes or three cigarettes or a pack of cigarettes a day, you know. I like to smoke a cigarette every once in a while, stimulate the lungs a little bit give the white blood cells and immune system and so on something to do. After all I spend the other half of my time detoxing just about every orifice. A small amount of something can have an almost opposite effect than a large amount of something . A little bit of pot, in a legal jurisdiction which goes without saying.
