The present study evaluates differences in risk perception related to marijuana use as a function of past use and, among those who report marijuana use, as a function of frequency of use and having experienced a consequence in the past. Participants were 725 incoming first year college students in a longitudinal study examining the efficacy of a marijuana prevention program. Analyses of cross-sectional data indicated that risk perception was greater among non-users of marijuana than for those who reported marijuana use (and, in turn, who were more likely to have actually experienced a drug-related consequence). Among marijuana users, risk perception was not influenced by the frequency of marijuana use nor was it influenced by the actual experience of a drug-related consequence. The findings suggest that for abstainers, perceived risk and the potential consequences of marijuana use may serve a protective role against the initiation of marijuana use. For those who use marijuana, intervention efforts utilizing motivation enhancement approaches could explore the discrepancy between perceived risks and actual experienced consequences.
本研究评估了与大麻使用相关的风险认知差异，该差异是过去使用情况的函数，并且在报告使用过大麻的人群中，是使用频率和过去是否经历过某种后果的函数。参与者是725名即将入学的一年级大学生，他们参与了一项关于大麻预防项目效果的纵向研究。横断面数据分析表明，大麻非使用者的风险认知高于报告使用过大麻的人（相应地，后者更有可能实际经历过与毒品相关的后果）。在大麻使用者中，风险认知不受大麻使用频率的影响，也不受与毒品相关后果的实际经历的影响。研究结果表明，对于戒除者而言，对大麻使用的感知风险和潜在后果可能对大麻使用的起始起到保护作用。对于那些使用大麻的人，采用动机增强方法的干预措施可以探究感知风险与实际经历后果之间的差异。
