Passive smoking--also called involuntary or environmental smoking--is the exposure of non-smokers to the tobacco smoke released by smokers. The physico-chemical composition of tobacco smoke, and notably its contents in toxic and carcinogenic substances, is the same in the secondary stream between puffs as in the primary stream released by the smoker. The pathogenic effects of passive smoking are increasingly well known and accepted. A high incidence of respiratory tract infections and of chronic respiratory and asthmatic symptoms is observed in children. In adults, passive smoking seems to be one of the main risk factors for cardiovascular diseases. Its repercussions on the respiratory tracts is difficult to evaluate, but there are marked by an increase of respiratory symptoms and perhaps of chronic obstructive lung diseases. Finally, it is now recognized that passive smoking is a major risk factor for primary lung cancer in non-smokers exposed to tobacco smoke.
被动吸烟——也称为非自愿或环境吸烟——是指不吸烟者接触吸烟者释放的烟草烟雾。烟草烟雾的物理化学成分，尤其是其中有毒和致癌物质的含量，在抽吸间隙的侧流烟雾中与吸烟者呼出的主流烟雾中是相同的。被动吸烟的致病作用日益为人所知并得到认可。在儿童中观察到呼吸道感染以及慢性呼吸道和哮喘症状的高发病率。在成年人中，被动吸烟似乎是心血管疾病的主要危险因素之一。其对呼吸道的影响难以评估，但表现为呼吸道症状增加，可能还有慢性阻塞性肺疾病。最后，现在人们认识到，被动吸烟是接触烟草烟雾的非吸烟者患原发性肺癌的主要危险因素。
