青少年吸烟者使用大麻（MJ）的比例高于非吸烟者。由于MJ吸烟通常涉及更深的吸入和更长的屏气比吸烟，我们假设更大的抽吸量，更长的抽吸持续时间和抽吸间隔，以及更高的抽吸速度在吸烟期间（1）使用MJ的青少年;（2）MJ吸烟发生在烟草（MBT）之前的青少年。103名接受戒烟治疗的烟草依赖青少年（66.0%女性，71.0%欧洲裔美国人，平均年龄15.3 +/- 1.25岁）在进入研究前在实验室吸了一支自己品牌的香烟。比较了当前娱乐性（14天内< 5天）MJ使用者（n = 25），当前重度（14天内大于或等于5天）MJ使用者（n = 22）和当前非MJ吸烟青少年（n = 56）的地形图和相关生理测量。最近的MJ吸烟史或物质开始的顺序在吸烟地形或生理措施没有差异。非裔美国青少年吸烟者比欧洲裔美国青少年吸烟者在吸烟前使用MJ。我们在青少年吸烟者中的发现与成人研究的结果一致，在成人研究中，MJ吸烟史与吸烟地形图的变化无关。(C)2004爱思唯尔有限公司保留所有权利。
7Adolescent tobacco smokers have higher rates of marijuana (MJ) use than nonsmokers. Because MJ smoking typically involves deeper inhalation and longer breathholding than tobacco smoking, we hypothesized greater puff volume, longer puff duration and puff interval, and higher puff velocity during tobacco smoking among (1) MJ-using teens; (2) teens whose onset of MJ smoking occurred before tobacco (MBT). One hundred and three tobacco-dependent adolescents presented for smoking cessation treatment (66.0% female, 71.0% European American, mean age 15.3 +/- 1.25 years) smoked one cigarette of their own brand in the laboratory prior to study entry. Topography and associated physiological measures among current recreational ( < 5 days in a 14-day period) MJ users (n = 25), current heavy ( greater than or equal to 5 days in a 14-day period) MJ users (n = 22) and current non-MJ-smoking teens (n = 56) were compared. There were no differences in tobacco smoking topography or physiological measures by recent MJ-smoking history or by order of substance initiation. Significantly more African American than European American adolescent smokers reported MJ use before tobacco. Our findings in adolescent smokers are consistent with results from adult studies in which history of MJ smoking was not associated with changes in tobacco smoking topography. (C) 2004 Elsevier Ltd.
