[Obstacles to stopping smoking among patients with vascular risk].
Despite the risk, smoking has only slightly decreased and the percentage of heavy smokers increases. The reason for the paradoxical situation has now been identified in more than 95% of the cases and is due to behaviour amplified by a pharmacological dependence on nicotine. The psycho-active effects of nicotine binding to nicotine receptors in the brain, produce a quasi constant physical dependence and a psychic dependence in certain smokers.
