Cannabis use is associated with a range of neurocognitive deficits, including impaired episodic memory. However, no study to date has assessed whether these difficulties extend to episodic foresight, a core component of which is the ability to mentally travel into one's personal future. This is a particularly surprising omission given that episodic memory is considered to be critical to engage episodic foresight.
In the present study, we provide the first test of how episodic foresight is affected in the context of differing levels of cannabis use, and the degree to which performance on a measure of this construct is related to episodic memory.
Fifty-seven regular cannabis users (23 recreational, 34 regular) and 57 controls were assessed using an adapted version of the Autobiographical Interview. The results showed that regular-users exhibited greater impairment of episodic foresight and episodic memory than both recreational-users and cannabis-naïve controls.
These data therefore show for the first time that cannabis-related disruption of cognitive functioning extends to the capacity for episodic foresight, and they are discussed in relation to their potential implications for functional outcomes in this group.
大麻使用与一系列神经认知缺陷有关，包括情景记忆受损。然而，迄今为止，没有研究评估这些困难是否会延伸到情景前瞻性，其核心组成部分是将思维带入个人未来的能力。鉴于情景记忆被认为是进行情景前瞻性的关键，这是一个特别令人惊讶的遗漏。
在本研究中，我们首次测试了在不同水平的大麻使用情况下，情景前瞻性如何受到影响，以及该结构的衡量标准的表现与情景记忆的关系程度。
57 名经常使用大麻的使用者（23 名娱乐性，34 名常规）和 57 名对照组使用自传式访谈的改编版进行了评估。结果表明，与娱乐性使用者和大麻无经验对照组相比，经常使用者表现出更严重的情景前瞻性和情景记忆受损。
因此，这些数据首次表明，与大麻相关的认知功能障碍会延伸到情景前瞻性，并且它们与该组的功能结果的潜在影响有关。
