In this research, we examine the effects of cannabis use on creativity and evaluations of creativity. Drawing on both the broaden-and-build theory and the affect-as-information model, we propose that cannabis use would facilitate more creativity as well as more favorable evaluations of creativity via cannabis-induced joviality. We tested this prediction in two experiments, wherein participants were randomly assigned to either a cannabis use or cannabis abstinence condition. We find support for our prediction that cannabis use facilitates joviality, which translates to more favorable evaluations of creativity of one's own ideas and others' ideas. However, our prediction that cannabis use facilitates creativity via joviality was not supported. Our findings suggest that cannabis use may positively bias evaluations of creativity but have no impact on creativity. Implications for theory and practice are discussed.

大麻的使用不会增加实际的创造力，但会影响对创造力的评估。

在这项研究中，我们研究了大麻使用对创造力和创造力评估的影响。借鉴扩展和构建理论和信息影响模型，我们提出大麻的使用将促进更多的创造力以及通过大麻引起的快乐对创造力进行更有利的评估。我们在两个实验中测试了这一预测，其中参与者被随机分配到大麻使用或大麻戒断状态。我们发现支持我们的预测，即大麻的使用促进了快乐，这转化为对一个人自己的想法和他人的想法的创造力的更有利的评估。然而，我们关于大麻的使用通过快乐促进创造力的预测没有得到支持。我们的研究结果表明，使用大麻可能会对创造力的评估产生积极影响，但对创造力没有影响。讨论了对理论和实践的影响。（PsycInfo 数据库记录 (c) 2023 APA，保留所有权利）。
