Tobacco: What You Don't Know Can Kill You
From VOA Learning English, this is the Health & Lifestyle report.
It is widely known that smoking tobacco can damage the lungs. But many people do not know that it can also cause heart disease and stroke.
That information comes from World Health Organization (WHO) officials in Geneva, Switzerland. The WHO marked May 31 as World No Tobacco Day. The WHO's 2018 campaign focuses on the damage smoking does to the cardiovascular system.
Health experts at the WHO say that cardiovascular diseases (CVD) kill about 18 million people each year. Tobacco use and secondhand smoke exposure cause nearly 17% of all heart disease deaths. They add that tobacco use is the second leading cause of cardiovascular disease, after high blood pressure.
Douglas Bettcher is the director for the prevention of non-communicable diseases at the WHO. He says most people know that smoking increases the risk of lung diseases and cancer. However, studies show many of these same people do not know that tobacco use can also cause heart attacks and stroke.
"There are major gaps in the knowledge of cardiovascular disease risks of tobacco use. And in many countries, these knowledge gaps are very substantial. The percentage of adults who do not believe that smoking causes stroke are, for example, in China, as high as 73 percent. For heart attacks, for example, 61 percent of adults in China are not aware that smoking increases the risk."
Knowledge is power.
And, in this case, knowledge can save lives. The WHO project manager of tobacco control is Vinayak Prasad. He says that in some cases, the body can repair the damage caused by tobacco use.
"(If) smokers stop smoking, the risk from cardiovascular diseases actually is gone in 15 years. So, 15 years after quitting, the risk of CVDs is the same as if you have never smoked."
The U.N. health agency says more than 80 percent of tobacco smokers live in developing countries. It adds that the number of smokers in the developing world is increasing.
However, there is good news about smoking and tobacco use in some parts of the world. The WHO reports that tobacco use worldwide fell from 27 percent in 2000 to 20 percent in 2016. And it says the number of smokers has decreased in all areas except for the Middle East and Africa.
Reuters news agency reports that anti-smoking gains are losing ground a little in China, the world's most populous country.
Reuters notes that in 2015, the Chinese government announced a series of measures that were part of the WHO's Framework Convention on Tobacco Control. The measures included a tax increase on tobacco products, written health warnings on cigarettes, limits on advertising and banning smoking in some public places.
Thanks to the government's actions, tobacco sales nationwide dropped for the first time since 2000. China's state media reports that in 2016 after officials in Beijing banned smoking in public places, tobacco sales dropped eight percent.
However, a public smoking ban recently failed in another of China's cities.
Hangzhou is a popular city for travelers. It is also home to Alibaba, the large internet business. Smokers in Hangzhou can still light up in some public spaces, such as train and bus stations as well as drinking establishments and karaoke clubs.
Reuters adds that the China National Tobacco Corporation led local opposition to a general, widespread ban on public smoking. The state-operated company is responsible for about seven to 11 percent of China's taxes.
And sales are rising. Reuters also reports that in 2017, China Tobacco sold 0.8 percent more cigarettes than the year before.
Experts at the WHO claim that, what they call, the "global tobacco epidemic" kills more than 7 million people each year. They add that close to 900,000 are non-smokers who die from breathing second-hand smoke.

这些信息由瑞士日内瓦的世界卫生组织（WHO）官员提供。世卫组织将5月31日定为世界无烟日 。世卫组织2018年的活动重点是吸烟对心血管系统造成的危害 。
世卫组织的健康专家说，每年死于心血管疾病的人数约1800万。在因心脏病发的死亡人数中，因吸烟或吸二手烟导致的死亡人数占17% 。他们还补充道，吸烟是仅次于高血压的第二大心脏疾病诱因 。
道格拉斯·巴彻（Douglas Bettcher）是世卫组织预防非传染性疾病科主任。他说，多数人都知道吸烟会加大患肺部疾病和癌症的风险 。然而，研究表示，这些人中的很多人并不知道吸烟也会引起心脏病和中风 。
“在吸烟对患心血管疾病风险的认知方面还存在着巨大差距。在很多国家，这些认知差距十分明显 。例如，在中国，认为吸烟不会导致中风的成年人高达73% 。此外，中国有61%的成年人不知道吸烟会加大患心脏病的风险 。
在这种情况下，知识能够挽救生命。世卫组织烟草控制项目经理维纳亚克·普拉萨德（Vinayak Prasad）表示，在某些情况下，人体能够修复吸烟造成的损害 。
然而，在世界的一些地区，也有关于吸烟的正面消息。世卫组织报告称，全球的烟草消耗量从2000年的27%下降至2016年的20% 。报告指出，除中东和非洲外，其他地区的吸烟人数均有所下降 。
