BBC纪录片 奇迹还是威胁 Horizon - E-Cigarettes: Miracle or Menace

传统烟草每年导致六七百万人非正常死亡，酒精每年导致三百多万人非正常死亡，白糖每年导致的非正常死亡也许超过前两者的总和。我们最终能完全戒掉这些不良嗜好吗？不知道。戒掉了这些不良嗜好后，我们会有新的不良嗜好吗？不知道。科学技术的每一次进步，都带绐我们一个更好的世界，而不是一个完美的世界，但这每一次的进步，都意义非凡。

罗永浩推荐

推荐这部BBC拍摄的电子烟专题纪录片。简单的说，主要结论是：1短期的看，电子烟的危害比传统烟草小很多，长期的看，因为缺乏研究数据，不知道电子烟会不会有其他目前未知的危害；2烟民改吸电子烟会明显减轻危害，但因为电子烟仍然有害健康，所以非烟民吸电子烟是愚蠢的。希望戒不了传统烟草的烟民改吸电子烟，希望所有的非烟民都不要碰电子烟，希望更多的公众关注电子烟行业的发展，希望电子烟行业的国家标准尽快出台。

Michael Mosley investigates the dramatic rise in e-cigarettes. They're everywhere these days, but what does the latest scientific research on them reveal? Michael reveals what e-cigarettes are really doing to your health. Are they really better for you than cigarettes? What is actually in them? Is passive vapour harmful? And can they really stop you from smoking? Michael meets some of the scientists around the world studying them, asks a group of volunteers to try to give up smoking regular cigarettes using them, and even takes up 'vaping' himself, smoking an e-cigarette every day for a month to see the effects on his own health - no easy task for such a committed non-smoker.
