对于老烟枪们来说,只要减少所吸香烟的数量是否就能相应减少有毒物质的摄入,从而减轻对人体的危害呢?研究人员的最新成果发现,并非如此。烟瘾很大的人,即使减少了吸烟数量,他们的身体仍会通过增加抽吸香烟(或其烟雾)的频率等方式尽量摄入能够满足他们身体曾经需要的量。看来戒烟必须彻底。 For the old smokers, as long as the number of cigarettes smoked is reduced, the intake of toxic substances can be reduced accordingly, thereby reducing the harm to the human body. The latest results of researchers found that this is not the case. People with high levels of cigarette addiction, even if they reduce the number of cigarettes smoked, will continue to ingest the amount of cigarettes (or their smoke) that they can use to meet their body’s previous needs. It seems that smoking cessation must be thorough.
