One of the human minds strongest traits is to justify its behaviours, even if the real reason is not understood. You don't believe you would do something that you don't enjoy doing, so logically you must enjoy smoking? Its a persuasive trick of the underlying addiction. How can you tell the difference between genuine pleasure, and the relief from escaping impending withdrawals? A glass of cold water is enjoyable on a hot day because your body needs it. Can you remember what it was like before the addiction took over? If you're an average smoker, then how many of the 7300 cigarettes have you really enjoyed in the last year? Long term, how confident are you that the 'pleasure' of smoking is actually costing you much more happiness?
