Principale raison pour arrêter de fumer: le coût du tabac

Une étude française montre que les principales raisons invoquées pour arrêter de fumer sont le coût (65% des personnes interrogées), l'amélioration de la condition physique (53%), la peur d'un avenir maladies liées au tabagisme (43%), la lassitude de tabac (34%), et la pression sociale (30%).

Radioactive Smoke: A Dangerous Isotope Lurks in Cigarettes

The tobacco industry has known for decades how to remove a dangerous isotope from cigarettes but has done nothing about it. The government now has the power to force a change

By Brianna Rego

In November 2006 former KGB operative Alexander Litvinenko died in a London hospital in what had all the hallmarks of a cold warstyle assassination. Despite the intrigue surrounding Litvinenko's death, the poison that killed him, a rare radioactive isotope called polonium 210, is far more widespread than many of us realize: people worldwide smoke almost six trillion cigarettes a year, and each one delivers a small amount of polonium 210 to the lungs. Puff by puff, the poison builds up to the equivalent radiation dosage of 300 chest x-rays a year for a person who smokes one and a half packs a day.

Although polonium may not be the primary carcinogen in cigarette smoke, it may nonetheless cause thousands of deaths a year in the U.S. alone. And what sets polonium apart is that these deaths could be avoided with simple measures. The tobacco industry has known about polonium in cigarettes for nearly 50 years. By searching through internal tobacco industry documents, I have discovered that manufacturers even devised processes that would dramatically cut down the isotope's concentrations in cigarette smoke. But Big Tobacco consciously decided to do nothing and to keep its research secret. In consequence, cigarettes still contain as much polonium today as they did half a century ago...

Polonium would be an excellent first poison to ban from tobacco. It is a single isotope, rather than a complex ingredient of smoke. Other poisonssuch as tar or carbon monoxideare difficult to keep out of the smoke, but polonium is not. The industry's four decades of research could give the FDA a head start toward getting concrete results. Moreover, some of the same steps that would reduce polonium concentrations in smokesuch as washing tobacco leavesmight also help remove toxic metals such as lead, arsenic and cadmium. This is precisely the kind of regulation and change the FDA now has the power to enforce.

The World Health Organization has made clear that smoking is the most avoidable cause of death. It estimates that 1.3 million people die of lung cancer worldwide every year, 90 percent because of smoking. If polonium had been reduced through methods known to the industry, many thousands of those deaths could have been avoided. The industry's lawyers made the conscious choice not to act on the results of their own scientists' investigations. But it is the customers who have had to live withand die fromthat decision.

In Brief

Tobacco plants accumulate small concentrations of polonium 210, a radioactive isotope that mostly originates from natural radioactivity in fertilizers.

Smokers inhale the polonium, which settles in hot spots in the lungs and can cause cancer. Its effects may lead to thousands of deaths a year in the U.S. alone.

The tobacco industry has known for decades how to virtually eliminate the polonium from cigarette smoke but kept its knowledge secret and failed to act.

The Food and Drug Administration now has the authority to regulate tobacco and could begin to use it by forcing manufacturers to reduce polonium content.
