This study explored the relationships between marijuana knowledge, confidence in knowledge, and information efficacy and marijuana use. Furthermore, the effects of the knowledge-related variables were examined on intention to use, resistance efficacy, and intention to vote for legalization. Undergraduate students ( = 215) were surveyed in Fall 2018. Data were collected online and analyzed through a series of regression analyses. Higher knowledge was related to less use via higher perceived risk whereas higher confidence in knowledge was related to more use. Marijuana use was related to higher future intention to use, lower resistance self-efficacy, and intention to vote for legalization. Information efficacy was related to intention to vote for legalization only. Students with more knowledge were less likely to use marijuana, whereas students who considered themselves well-informed were more likely to use it. Future intervention efforts will benefit from counteracting students' misplaced confidence in their knowledge.
本研究探讨了大麻知识、知识信心、信息效力与大麻使用之间的关系。此外，还检验了知识相关变量对使用意图、抵制效力和支持合法化投票意向的影响。2018 年秋季对本科生（ = 215）进行了调查。数据通过一系列回归分析在线收集和分析。较高的知识与较高的感知风险相关，因此与较低的使用相关，而较高的知识信心与较高的使用相关。大麻使用与更高的未来使用意图、更低的抵制自我效能和支持合法化投票的意向相关。信息效力仅与合法化投票意向相关。知识较多的学生不太可能使用大麻，而自认为知识渊博的学生则更有可能使用大麻。未来的干预措施将受益于纠正学生对自身知识的错误信心。
