I enjoy smoking - The difference between heroin and nicotine is that one chemical delivers a tremendous high while the other is far more addictive. Studies have long ranked nicotine as a more addictive substance than either heroin or cocaine. Cocaine's generally recognized addiction rate among regular users is 15% while nicotine's is over 70%. Imagine convincing your mind that it "likes" being addicted to the drug that most addiction scientists now rank as the most addictive substance on earth. We are nicotine addicts. A pack a day smoker smokes 7,300 cigarettes each and every year. How many of your last 7,300 smokes did you really enjoy? How many of the next 7,300 will bring joy to your life? Isn't the true joy of being a well fed nicotine addict in not having to feel the discomfort associated with withdrawal?
