Recent research suggests that not only does the use of recreational drugs impact on working memory functioning, but more ;everyday' aspects of memory (e.g. remembering to do something in the future) are also affected. Forty-three ecstasy-polydrug users and 51 non-ecstasy users were recruited from a university population. Each participant completed the Cognitive Failures Questionnaire (CFQ) and Everyday Memory Questionnaire (EMQ). Of these, 28 ecstasy-polydrug users and 35 non-ecstasy users completed the Prospective Memory Questionnaire (PMQ). In addition, an objective measure of cognitive failures (the CFQ-for-others) was completed by friends of participants. With the exception of the CFQ-for-others, in each regression equation, cannabis emerged as the only significant predictor of everyday and prospective memory deficits. Significant correlations were found between the different indicators of everyday memory and various measures of illicit drug use. Cannabis featured prominently in this respect. The present study provides further support for cannabis related deficits in aspects of everyday memory functioning. Ecstasy may aLso be associated with cognitive slips, but not to the same extent as cannabis.
近期研究表明，使用消遣性药物不仅会影响工作记忆功能，而且记忆的更多“日常”方面（例如记住未来要做的某事）也会受到影响。从一所大学的人群中招募了43名摇头丸多药使用者和51名非摇头丸使用者。每位参与者都完成了认知失误问卷（CFQ）和日常记忆问卷（EMQ）。其中，28名摇头丸多药使用者和35名非摇头丸使用者完成了前瞻性记忆问卷（PMQ）。此外，参与者的朋友完成了一项认知失误的客观测量（他人CFQ）。除他人CFQ外，在每个回归方程中，大麻都是日常和前瞻性记忆缺陷的唯一显著预测因素。在日常记忆的不同指标与非法药物使用的各种测量之间发现了显著相关性。大麻在这方面表现突出。本研究为日常记忆功能方面与大麻相关的缺陷提供了进一步支持。摇头丸也可能与认知失误有关，但程度不如大麻。
