Data from the Tucson epidemiological study of airways obstructive disease on smoking of non-tobacco cigarettes such as marijuana were analysed to determine the effect of such smoking on respiratory symptoms and pulmonary function. Among adults aged under 40, 14% had smoked non-tobacco cigarettes at some time and 9% were current users. The prevalence of respiratory symptoms was increased in smokers of non-tobacco cigarettes. After tobacco smoking had been controlled for men who smoked non-tobacco cigarettes showed significant decreases in expiratory flow rates at low lung volumes and in the ratio of the forced expiratory volume in one second to the vital capacity. This effect on pulmonary function in male non-tobacco cigarette smokers was greater than the effect of tobacco cigarette smoking. These data suggest that non-tobacco cigarette smoking may be an important risk factor in young adults with respiratory symptoms or evidence of airways obstruction.
对图森市气道阻塞性疾病流行病学研究中关于吸食大麻等非烟草类香烟的数据进行了分析,以确定此类吸烟对呼吸道症状和肺功能的影响。在40岁以下的成年人中,14%的人曾在某个时候吸食过非烟草类香烟,9%的人是当前使用者。吸食非烟草类香烟者呼吸道症状的患病率有所增加。在对吸烟情况进行控制后,吸食非烟草类香烟的男性在低肺容量时的呼气流量率以及一秒用力呼气量与肺活量的比值均显著下降。吸食非烟草类香烟对男性肺功能的这种影响大于吸食烟草类香烟的影响。这些数据表明,吸食非烟草类香烟可能是有呼吸道症状或气道阻塞证据的年轻人的一个重要风险因素。
