摘要

Smoking causes a third of cancer deaths, but quitting brings immediate benefit. In fact, someone who quits before the age of 50 is half as likely to die of cancer in the subsequent 15 years as he would be if he kept smoking. The trick, then, is helping people quit. With that goal in mind, Cytos Biotechnology, in Zurich, has, as it announced to the American Society of Clinical Oncology meeting held last week in Florida, made progress in developing a vaccine against nicotine. Normally, when someone smokes a cigarette, the nicotine in it is carried to his brain in the bloodstream. Once there, it stimulates a neural circuit that provides a sensation of pleasure. That sensation reinforces the desire for another cigarette, making it hard to relinquish the habit.
