This study examines normative misperceptions in a sample of participants recruited for a brief intervention trial targeting risky cannabis use.
Participants who were concerned about their own risky cannabis use were recruited to help develop and evaluate intervention materials. At baseline, participants reported on their own cannabis use and provided estimates of how often others their gender and age used cannabis in the past 3 months. Comparisons were made between participants estimates of others cannabis use with reports of cannabis use obtained from a general population survey conducted during a similar time period.
Participants (N = 744, mean age = 35.8, 56.2% identified as female) largely reported daily or almost daily cannabis use (82.4%). Roughly half (55.3%) of participants estimated that others their age and gender used cannabis weekly or more often in the past 3 months, whereas the majority of people in the general population reported not using cannabis at all.
Normative misperceptions about cannabis use were common in this sample of people with risky cannabis use. Limitations and possible future directions of this research are discussed, as well as the potential for targeting these misperceptions in interventions designed to motivate reductions in cannabis use.

本研究调查了一组因针对危险大麻使用的简短干预试验而招募的参与者中的规范认知偏差。
招募了那些担心自己危险大麻使用行为的参与者，以帮助开发和评估干预材料。在基线时，参与者报告了自己的大麻使用情况，并估计了与他们年龄和性别的其他人在过去3个月内使用大麻的频率。将参与者对他人大麻使用情况的估计与同期进行的一项普通人群调查中获得的大麻使用报告进行了比较。
参与者（N = 744，平均年龄 = 35.8岁，56.2% 为女性）大多报告每天或几乎每天使用大麻（82.4%）。大约一半（55.3%）的参与者估计，与他们年龄和性别的其他人在过去3个月内每周或更频繁地使用大麻，而普通人群中的大多数人报告根本不使用大麻。
在这个有危险大麻使用行为的样本中，对大麻使用的规范认知偏差很常见。讨论了本研究的局限性和可能的未来方向，以及在旨在促使减少大麻使用的干预措施中针对这些认知偏差的可能性。
