肺癌患者：电子香烟有利还是有弊？
2016/07/27
摘要
电子香烟的使用仍有争议，因为从烟草转变为电子香烟对耐受性和健康价值的短期和长期的影响，其科学证据是有争议的。然而，电子香烟和电子液体质量已有所提高。大多数电子液体的主要的成分：丙二醇、植物甘油和尼古丁是药品级。香料均为食品级。高质量的成分减少了电子液体中的杂质。电子烟的排放，不含固体颗粒或一氧化碳。亚硝胺含量比烟草烟雾中至少低一百倍。正常使用的电子烟的排放，除尼古丁外，不含任何显著有害成分。英国公共卫生当局表示，使用电子香烟的毒性可能至少比吸食烟草少95%。一个良好监管的法律市场是有好处的。在不允许含有尼古丁的电子液体的国家，“自己动手”制作的液体很普遍，处理过程有风险，有时可能含有有毒杂质。虽然电子香烟对非吸烟者来说，绝不应该被认为是安全的产品，但对于吸烟者来说，电子烟比香烟至少安全20倍。在电子烟中含尼古丁的国家，在患者的请求下，戒烟专家提供越来越多建议，劝告患者使用电子烟来戒烟或减少抽烟频率。基于目前的认知，对有肺癌或其它癌症的患者，他们如果仍要继续吸烟，电子烟提供了一种疾病治疗期间戒烟以外的替代方案。

Abstract
E-cigarettes remain controversial because the scientific evidence of short term and long term effects on tolerance and the health value of a switch from tobacco to e-cigarettes is contested and controversial. Nevertheless the quality of e-cigarettes and e-liquids has improved. The main ingredients, propylene glycol, vegetable glycerine and nicotine are pharmaceutical-grade quality in most e-liquids. Flavors are almost all food grade. The high quality of ingredients has decreased the presence of impurities in e-liquids. The emissions of e-cigarettes do not contain solid particles or carbon monoxide. Nitrosamine content is at least one hundred times lower than in tobacco smoke. E-cigarette emissions in normal use do not contain any harmful constituents at significant levels except nicotine. UK public health authorities have stated that e-cigarette use is likely to be at least 95% less toxic than cigarette use. There are benefits from having a well-regulated legal market. In countries where e-liquid containing nicotine is not allowed, "do-it-yourself" liquids are common and have handling risks and may sometimes contain toxic impurities. Though e-cigarettes should never be assumed safe products for non-smokers, for smokers, the e-cigarette is at least 20 times less dangerous than the cigarette. Tobacco cessation specialists in countries where nicotine containing e-cigarettes are available increasingly provide counselling for e-cigarette use to stop smoking or to reduce smoking at the request of patients. Based on current knowledge, for patients with lung or other forms of cancer who would otherwise continue to smoke, e-cigarettes offer an alternative way to quit smoking while they undergo medical treatment.
