Les obstacles à la cigarette électronique

RENNES – Michael Russell et Murray Jarvik, deux chercheurs à l’avant-garde de la recherche sur le sevrage tabagique dans les années 1970, se seraient sans doute félicités du développement de la cigarette électronique ou vaporisateur personnel (VP) de nicotine. Outre le fait qu’ils soient une aide temporaire pour ceux qui tentent d’arrêter de fumer, ces nouveaux dispositifs de distribution de nicotine pourraient être des alternatives durables au tabac et donc permettre une éradication presque totale de la consommation des produits du tabac.

Nous savons depuis longtemps que les gens fument pour la nicotine, mais qu’ils meurent à cause de la fumée. En fait, la grande majorité des maladies et décès liés au tabagisme sont provoqués par l’inhalation de particules de goudron et de gaz toxiques, dont le monoxyde de carbone. Si les thérapies de substitution à la nicotine (TSN) ont permis à de nombreux fumeurs d’arrêter de fumer, le tabagisme reste très répandu dans de nombreux pays.

L’absorption de nicotine par des moyens sans combustion, comme le tabac sans fumée ou le vapotage, permettrait à des millions de fumeurs de réduire considérablement les risques qu’ils font courir à leur santé. En Suède, la consommation généralisée de snus – de la poudre de tabac humide qui se consomme oralement, avec une plus faible concentration de nitrosamines cancérigènes – a très fortement réduit l’incidence de cancer du poumon, devenue l’une des plus faibles au monde.

    Empowering China’s New Miracle Workers

    China’s success in the next five years will depend largely on how well the government manages the tensions underlying its complex agenda. In particular, China’s leaders will need to balance a muscular Communist Party, setting standards and protecting the public interest, with an empowered market, driving the economy into the future.

    The Sovereignty that Really Matters

    The preference of some countries to isolate themselves within their borders is anachronistic and self-defeating, but it would be a serious mistake for others, fearing contagion, to respond by imposing strict isolation. Even in states that have succumbed to reductionist discourses, much of the population has not.

    Resurrecting Creditor Adjustment

    When the Bretton Woods Agreement was hashed out in 1944, it was agreed that countries with current-account deficits should be able to limit temporarily purchases of goods from countries running surpluses. In the ensuing 73 years, the so-called "scarce-currency clause" has been largely forgotten; but it may be time to bring it back.

    Trump’s Republican Collaborators

    Republican leaders have a choice: they can either continue to collaborate with President Donald Trump, thereby courting disaster, or they can renounce him, finally putting their country’s democracy ahead of loyalty to their party tribe. They are hardly the first politicians to face such a decision.

    How Money Could Unblock the Brexit Talks

    With talks on the UK's withdrawal from the EU stalled, negotiators should shift to the temporary “transition” Prime Minister Theresa May officially requested last month. Above all, the negotiators should focus immediately on the British budget contributions that will be required to make an orderly transition possible.

    Is Vladimir Putin Losing His Grip?

    In recent decades, as President Vladimir Putin has entrenched his authority, Russia has seemed to be moving backward socially and economically. But while the Kremlin knows that it must reverse this trajectory, genuine reform would be incompatible with the kleptocratic character of Putin’s regime.

    Don’t Bank on Bankruptcy for Banks

    As a part of their efforts to roll back the 2010 Dodd-Frank Act, congressional Republicans have approved a measure that would have courts, rather than regulators, oversee megabank bankruptcies. It is now up to the Trump administration to decide if it wants to set the stage for a repeat of the Lehman Brothers collapse in 2008.
