我看见有关资料上说：“一只香烟可产生五百毫升烟雾，烟雾中含有三千多种化学物质，其中二十多种被确认为致癌物。最早从烟草中提取出来的尼古丁，即使吸烟者成瘾也使吸烟者中毒。以后科学家又从香烟中分离出苯并芘和甲基肼，它们都是较强致癌物，长期吸烟就会得各类癌。吸烟也会污染环境，而且对下一代有影响。香烟还是一种慢性自***的毒药。一支香烟可毒死一只老鼠，二十支香烟可毒死一头牛。”有资料表明：“有一个人连续吸了六十只烟，会当场死亡”。戒烟已成为世界性的潮流，所以联合国把每年的5月30日为“世界无烟日”

论吸烟作文800字【五】
吸烟的危害尽人皆知，但“吸烟”仍然成为当今一个极为普遍的现象。从年迈的爷爷、奶奶到十几岁的青年都有“人手一支烟”这种不良嗜好。香烟，竟有这样的魔力，让瘾君子如此迷恋。禁烟，竟有这样的困难，让戒烟者痛苦万分。
记得，我小时候就看过姥爷吸烟的模样。据说，姥爷已经有几十年的“烟龄”了。他老人家常常右手持烟，叼入口里深吸一口，那样子别提多满足、自在了。然后，几个白色的烟圈便从他嘴里慢慢地吐出来，可又从两个鼻孔里吸了回去，就这样进进出出，好似龙王爷吞云吐雾一般。到最后，浓浓的烟雾又从他嘴里喷薄而出，空气里立刻弥漫着一股烟草刺鼻的辣味。我站在一旁，被姥爷吐出的“二手烟”呛得不停地咳嗽，连忙冲他大喊：“姥爷，别吸烟了！别吸烟了！”姥爷却手一扬，满不在乎地笑了笑，嘴里不经意地露出了黄斑斑的牙齿，说：“丫头片子管什么！我身体好着呢，能出啥事儿！”说着，又掏出一支烟，美滋滋地递到嘴边。有时姥爷烟瘾上来了，多吸了几支，不免遭姥姥埋怨。“你呀你，唉，让人怎么说呢。说了多少次“吸烟有害健康”，你怎么不听劝呢？”姥爷却仍不当回事：“饭后一支烟，身体赛过活神仙，没事没事。”说话间又去吐烟圈去了。后来，在我上一年级的时候，姥爷因为吸烟过多，整天咳嗽个不停，愁眉不展。我知道，如果姥爷早点听从我们的忠告，把吸烟的陋习戒掉，现在也不至于如此痛苦。
