Marijuana use holds a curvilinear relation to sexual orientation, whereby bisexual individuals reporter higher frequency of use than exclusively hetero- or homosexual individuals. This relation differs by gender, with more pronounced differences among women. Bisexual individuals are at greater risk for negative consequences of marijuana use, such as dependence. To mitigate potential risks, individuals employ protective behavioral strategies (PBS). While differences in use are known, research has yet to examine if consequences and PBS use vary by sexual orientation. This study seeks to address the relations between sexual orientation, consequences, gender, and PBS. It was hypothesized that orientation would be associated with consequences, mediated by PBS, and these relations would vary by gender. College students (N = 8141) from 11 different universities completed an online survey measuring marijuana consequences, PBS use, and sexual orientation. A final analytic sample (n = 2091) was composed of participants who indicated past 30-day marijuana use (60% women, 64% White, mean age 19.92). Path analysis was used to test all study hypothesis. Results indicated a curvilinear relation between sexual orientation and consequences among men, however not women. Moreover, PBS use mediated the relation between orientation and consequences among men, and negatively predicted consequences among women. Conclusions include that mixed sexual orientation men experience higher consequences through lower PBS use. For women, PBS use buffers against consequences. These findings reflect a general effectiveness of PBS use for mitigating negative marijuana-related consequences. The implications of these results are discussed.
大麻使用与性取向呈曲线关系，双性恋个体报告的使用频率高于异性恋或同性恋个体。这种关系因性别而异，女性的差异更为明显。双性恋个体使用大麻的负面影响风险更高，例如依赖。为了减轻潜在风险，个体采用保护性行为策略（PBS）。虽然使用情况存在差异，但研究尚未探讨性取向是否会影响后果和 PBS 使用。本研究旨在探讨性取向、后果、性别和 PBS 使用之间的关系。研究假设性取向与后果之间存在关联，PBS 使用起中介作用，并且这些关系因性别而异。来自 11 所不同大学的大学生（N=8141）完成了一项在线调查，测量大麻的后果、PBS 使用和性取向。最终分析样本（n=2091）由过去 30 天内使用过大麻的参与者组成（60%为女性，64%为白人，平均年龄为 19.92 岁）。路径分析用于检验所有研究假设。结果表明，男性的性取向和后果之间呈曲线关系，但女性并非如此。此外，PBS 使用在男性的性取向和后果之间起中介作用，并对女性的后果产生负向预测作用。结论包括，混合性取向的男性通过降低 PBS 使用来体验更高的后果。对于女性来说，PBS 使用缓冲了后果。这些发现反映了 PBS 使用在减轻大麻相关负面影响方面的普遍有效性。讨论了这些结果的含义。
