Abstract

Objective

Nonmedical use of prescription stimulants (NPS) continues to be a concern on college campuses. Previous research demonstrates a strong link between NPS and use of other substances, particularly alcohol and marijuana among college students. Simultaneous use of NPS with other substances has become an increasing concern. Given the high rates of NPS and simultaneous NPS with other substances, research examining substance use patterns and motives among students is warranted. Method: This study evaluated group differences in alcohol and marijuana use patterns, consequences, and motives among college students: a) with no NPS history (No NPS); b) engaged in NPS with no simultaneous use (Non-Sim NPS); and c) engaged in simultaneous NPS with alcohol and/or marijuana (Sim NPS). Participants included 1,108 students from three universities who reported past-year marijuana and alcohol use. Results: Overall, 32.8% reported lifetime NPS with 12.5% indicating NPS in the previous 3 months, of which 51.1% reported simultaneous NPS with alcohol and 40.2% with marijuana. Significant group differences for all drinking and marijuana outcomes were found, with heaviest rates among the Sim NPS group, followed by the Non-Sim NPS group, and the No NPS group. The Sim NPS group reported greater motives for using marijuana to alter the effects of other substances. Conclusions: College students engaged in simultaneous NPS with alcohol and marijuana are a high-risk group that should be the focus of prevention and intervention programs in the campus setting.

处方兴奋剂与酒精和大麻同时使用的模式、后果和动机

摘要

客观的

处方兴奋剂 (NPS) 的非医疗使用仍然是大学校园关注的问题。先前的研究表明，NPS 与其他物质的使用之间存在密切联系，尤其是大学生中的酒精和大麻。将 NPS 与其他物质同时使用已成为越来越受关注的问题。鉴于 NPS 和与其他物质同时 NPS 的高比率，有必要研究检查学生的物质使用模式和动机。方法：本研究评估了大学生在酒精和大麻使用模式、后果和动机方面的群体差异：a) 没有 NPS 历史 (No NPS)；b) 从事没有同时使用的 NPS（Non-Sim NPS）；c) 与酒精和/或大麻同时进行 NPS（Sim NPS）。参与者包括来自三所大学的 1,108 名学生，他们报告了过去一年的大麻和酒精使用情况。结果：总体而言，32.8% 的人报告了终生 NPS，12.5% 的人表示过去 3 个月的 NPS，其中 51.1% 的人报告了与酒精同时发生的 NPS，40.2% 的人报告了与大麻同时发生的 NPS。发现所有饮酒和大麻结果的显着组间差异，Sim NPS 组的比率最高，其次是非 Sim NPS 组和无 NPS 组。Sim NPS 小组报告了使用大麻来改变其他物质影响的更大动机。结论：同时从事酒精和大麻 NPS 的大学生是高危人群，应成为校园环境中预防和干预计划的重点。
