OBJECTIVES
Knowledge about the roles that heavy alcohol and cigarette use play in patterns of concurrent substance use among adolescents is lacking despite studies showing that adolescent substance users are typically multisubstance users and that alcohol and cigarettes are commonly used heavily by those who use illicit substances.
METHODS
The roles of increasing use and heavy first-time use of alcohol and cigarettes in multisubstance use patterns were examined in a cohort of 4192 secondary students who were surveyed three times over a 4-year period.
RESULTS
When subsequent use patterns were compared for students who increased their levels of alcohol or cigarette use and those who initiated use for the first time but at heavy frequencies, analyses indicated that the former group was more likely to initiate the subsequent use of other substances and to maintain and increase use already initiated.
CONCLUSIONS
These results suggest that adolescents are likely to have been involved in a history of licit substance use characterized by increasing levels of use before progressing to and maintaining the use of other substances. Increasing frequencies of alcohol and cigarette use, therefore, may be markers for more serious patterns of substance use.
目的
尽管有研究表明青少年物质使用者通常是多物质使用者，且使用非法物质的人通常大量使用酒精和香烟，但目前仍缺乏关于大量饮酒和吸烟在青少年同时使用多种物质模式中所起作用的知识。
方法
在一个由4192名中学生组成的队列中，研究了酒精和香烟使用量增加以及首次大量使用在多物质使用模式中的作用。该队列在4年时间里接受了三次调查。
结果
当比较酒精或香烟使用量增加的学生与首次大量使用的学生的后续使用模式时，分析表明，前一组更有可能开始后续使用其他物质，并维持和增加已开始的使用。
结论
这些结果表明，青少年可能有过合法物质使用史，其特征是在开始使用并维持其他物质使用之前，使用量不断增加。因此，酒精和香烟使用频率的增加可能是更严重物质使用模式的标志。
