But I like the taste and smell of cigarettes

Really! and that's enough reason to poison yourself and risk having horrible diseases like cancer, stroke, and diabetes just to name few? Go back in time to your first memory of smoking, was the taste good? it was so repulsive that you probably coughed or vomited and you thought "I'll never get hooked to that!" Then you smoked again to get over that taste so you look cool smoking and as you kept smoking your immune system built tolerance to that poison and you got used to that bad taste and smell to the point of liking it. cigarettes don't genuinely have a good taste or smell, it's just the tolerance that your body built.
