They're only beginning to understand just how addictive nicotine really is, and why the habit is so hard to break for some people. From the article linked below on Macalester College's website:
"Nicotine's pharmacokinetic properties have been found also to enhance its abuse potential. Cigarette smoking produces a rapid distribution of nicotine to the brain, with drug levels peaking within 10 seconds of inhalation. This fast delivery of drug assures that the smoker receives instant reinforcement for smoking, this perpetuates the continuation of smoking. The acute effects of nicotine dissipate in a few minutes, making the smoker continue dosing frequently throughout the day in order to maintain the drug's pleasurable effects and prevent the uncomfortable symptoms of withdrawal. What people frequently do not realize is that the cigarette is a very efficient and highly engineered drug-delivery system. By inhaling, the smoker can get nicotine to the brain very rapidly with every puff. A typical smoker will take 10 puffs on a cigarette over a period of 5 minutes in which the cigarette is lit. Thus, a person who smokes about 1-1/2 packs (30 cigarettes) daily, will get 300 "hits" of nicotine to the brain each day. These factors contribute considerably to nicotine's highly addictive nature."
