The combined use of cannabis and tobacco is frequent in Europe. Few studies have nonetheless explored this pattern of consumption and its relationship with academic achievement in Spanish population. The aim of the present study was to analyze (1) the frequency of four patterns of polydrug use the last year (non-dual users of cannabis and tobacco; concurrent users: cannabis and tobacco separately; simultaneous users: tobacco in cannabis "joints"; simultaneous users: tobacco in cannabis joints alongside alcohol) by gender and age; (2) grade point average (GPA) by gender and age; (3) the association between the frequency of the four patterns of use and the GPA amongst a sample of 477 Spanish university students. The use of cannabis and tobacco (concurrent and simultaneous) and GPA were assessed by means of self-reported questionnaires. Statistically significant differences were found for the GPA with respect to gender. The GPA by the non-dual users of cannabis and tobacco was significantly higher than the GPA corresponding to the concurrent and simultaneous users. The combined use of cannabis and tobacco, regardless of the type of use (concurrent or simultaneous), is moderately related to poor academic achievement amongst university students.
在欧洲，大麻和烟草的联合使用很常见。然而，很少有研究探讨西班牙人群中的这种消费模式及其与学业成绩的关系。本研究的目的是分析：（1）去年四种多药使用模式（大麻和烟草的非双重使用者；同时使用者：分别使用大麻和烟草；同时使用者：在大麻“烟卷”中使用烟草；同时使用者：在含酒精的大麻烟卷中使用烟草）按性别和年龄划分的频率；（2）按性别和年龄划分的平均绩点（GPA）；（3）在477名西班牙大学生样本中，四种使用模式的频率与GPA之间的关联。通过自我报告问卷评估大麻和烟草的使用情况（同时使用和同时使用）以及GPA。发现GPA在性别方面存在统计学上的显著差异。大麻和烟草的非双重使用者的GPA显著高于同时使用者和同时使用者对应的GPA。大麻和烟草的联合使用，无论使用类型（同时使用或同时使用），都与大学生学业成绩不佳有适度关联。
