摘要

大麻是美国使用最多的联邦非法药物。了解青少年和新成人在估计其大麻使用量方面的准确性非常重要，因为这为了解和研究与大麻使用相关的结果奠定了基础。本研究旨在评估以克为单位的典型大麻数量的准确性，并确定美国青少年和新成人的准确性预测因素。报告在过去 30 天内使用过大麻的参与者（n = 50；年龄在 14-21 岁之间）完成了大麻使用特征和问题的测量，被要求使用大麻替代品 "目测 "他们一般大麻中的大麻量，并估算出克数。然后以克为单位对大麻替代品进行称重。配对样本 t 检验表明，参与者估算的大麻中的克数（M=.82；SD=0.46）明显多于代用物质的实际含量（M=.47；SD=0.21；t(49) = 6.32，p(49) = 0.46）。

Understanding US adolescents’ and emerging adults’ overestimation of their cannabis use quantity

Cannabis is the most used federally illicit drug in the United States (U.S). Understanding how accurate adolescents and emerging adults are at estimating their cannabis use quantity is important, as this lays the groundwork for understanding and studying the outcomes associated with cannabis use. This study aimed to assess the accuracy of cannabis quantity in grams for a typical joint and identify predictors of accuracy among U.S. adolescents and emerging adults. Participants (n = 50; aged 14–21) who reported using joints in the past 30 days completed measures of cannabis use characteristics and problems, were asked to “eyeball” the amount of cannabis in their average joint using a cannabis substitute and estimated the number of grams. The cannabis substitute was then weighed in grams. Paired samples t-tests indicated that participants estimated significantly more grams in a joint (M=.82; SD = 0.46) than the actual amount of the surrogate substance (M=.47; SD = 0.21; t(49) = 6.32, p < 0.001, d = 0.89). A linear regression analysis indicated that the age of cannabis initiation (B = -0.13, p=.002) and cannabis use problems (B = -0.03, p=.009) were negatively and significantly associated with discrepancies in estimated grams. Specifically, being older when first using cannabis and reporting more cannabis use problems were linked to less overestimation of grams per joint. These findings align with previous research demonstrating a tendency to overestimate cannabis quantity and contribute novel insights by identifying predictors of estimation accuracy. This study underscores the importance of considering age and cannabis-related problems when assessing the reliability of self-reported cannabis use quantities among adolescents and emerging adults.

期刊介绍： Addictive Behaviors is an international peer-reviewed journal publishing high quality human research on addictive behaviors and disorders since 1975. The journal accepts submissions of full-length papers and short communications on substance-related addictions such as the abuse of alcohol, drugs and nicotine, and behavioral addictions involving gambling and technology. We primarily publish behavioral and psychosocial research but our articles span the fields of psychology, sociology, psychiatry, epidemiology, social policy, medicine, pharmacology and neuroscience. While theoretical orientations are diverse, the emphasis of the journal is primarily empirical. That is, sound experimental design combined with valid, reliable assessment and evaluation procedures are a requisite for acceptance. However, innovative and empirically oriented case studies that might encourage new lines of inquiry are accepted as well. Studies that clearly contribute to current knowledge of etiology, prevention, social policy or treatment are given priority. Scholarly commentaries on topical issues, systematic reviews, and mini reviews are encouraged. We especially welcome multimedia papers that incorporate video or audio components to better display methodology or findings. Studies can also be submitted to Addictive Behaviors? companion title, the open access journal Addictive Behaviors Reports, which has a particular interest in ''non-traditional'', innovative and empirically-oriented research such as negative/null data papers, replication studies, case reports on novel treatments, and cross-cultural research.
