- New research suggests cannabis use could make a user more susceptible to “false memory.”
- 然而，专家说这是一个有些误导性的术语，使得调查结果听起来比他们真正的更为邪恶。
- Instead of being more susceptible to “false memories,” experts say a cannabis-impaired person is likely “more suggestible” and may recall inaccurate details when asked suggestive questions.
Past research from theWorld Health Organizationhas linked recreational cannabis use to impairing a person’s attention and delaying their reaction time, resulting in a doubled risk of fatal traffic accidents.
在短期内,大麻可以降低一个人的working memory, executive function, and attention.
但新的研究表明，大麻使用可以让用户更容易受到“虚假记忆”，一些专家说，一些专家说听起来比真的更为邪恶。
Arecent study在美国美国国家科学院的诉讼程序中发表的表明，大麻似乎增加了“虚假记忆”，这意味着他们可能声称记住不在那里的东西。
That doesn’t mean that normal cannabis use will make someone hallucinate dragons or their pets talking.
相反，他们更容易记住在测试中不受测试的话，更容易受到“基于建议的”错误的记忆，因为即使单剂量的大麻也表现出影响一个人的决策和工作记忆。
To test this effect, researchers in the Netherlands, Australia, Germany, and the United States recruited 64 healthy adult volunteers for their randomized, double-blind, placebo-controlled trial.
有些人被给予大麻，其他人得到了一个安慰剂。所有接受的内存测试，包括标准化和可信的单词测试，一直在虚拟现实中经过方案后转发信息，包括作为目击者和犯罪的犯罪者。
然后，一周后，通过在后续采访中以及通过虚拟共同证明，通过暗示问题的结合来引入错误信息。
总的来说，研究人员发现那些没有知道他们收到的大麻，这更有可能经历“增强的假记忆效应”，但有人当有人很高时大多数都会出现。
“虽然大麻与正效应有关（例如，减少疼痛），但它也可能导致朦胧的回忆，最终打开了负面影响的门：虚假记忆的增加，”研究结束。
研究人员说明的现实生活中，落在警察和其他调查人员上，这些调查人员正在寻求寻求目击者的最准确和真实的陈述，包括在大麻的影响下的人。
为此，研究人员注意，调查人员应该等待他们清醒，否则他们将更容易彻及确认领先的问题，不一定从他们可能刚才目睹的事件中拉出真实细节。
But they shouldn’t wait too long.
The researchers found that after a week, the high participants and the sober ones had about the same rate of memory recall, suggesting the effects of cannabis’ impact leveled out with our natural loss of memories in the short term.
纽约市玛丽克里顿博士大麻专家who wasn’t involved in the study, the findings suggest that whether people are sober or high, their ability to recall what they saw found a middle ground just a week later.
“That’s so strange,” Clifton told Healthline. “The sober people lost memory over time.”
这也是因为我们都会随着时间的推移而失去一些记忆，因为我们的大脑决定了重要的是什么，即使这包括1周前的犯罪细节。
Clifton says because of how cannabis interacts with the hippocampus — a part of the brain associated with memory — the findings between sober and high witnesses at a week later merit for more study.
Regardless, she says, as different substances work differently in the brain, finding truth in an investigation should involve considering the state a witness may be in.
“I don’t think police anywhere should be interviewing anyone who is high or drunk,” Clifton said.
In terms of the criminal justice system, the findings may be more helpful to defense attorneys or others who would cross-examine so-called eyewitnesses.
Or are people simply “more suggestible” when they’re high?
Dr. Jordan Tishler, a Harvard-educated physician and CEO ofinhalemd.谁也没有参与研究，发现它“疯狂地”的方法和方法，即通过混合具有较新技术的经验和真实方法，如虚拟现实。
但他确实在研究的标题中发出问题 - “大麻会增加对虚假记忆的敏感性” - 正如他所说的那样“唤起各种各样的鸟类”。
“The headline comes off as saying anybody who uses cannabis is untrustworthy, and I don’t think that was the authors’ intentions,” Tishler told Healthline.
Instead, he says, the findings suggest that people under the influence of cannabis are more agreeable and more likely to “go along to get along.”
Much like a child trying to please a parent, someone under the influence of cannabis may be more likely to follow along with leading questions.
Instead of being more susceptible to “false memories,” Tishler argues a cannabis-impaired person is “more suggestible.”
“Stoners would say ‘yes’ more,” Tishler said.
That means how a question is phrased is even more important.
For example, asking someone, “Did you see the white car?” while they’re high may get them to answer yes more often, even if the car was red, blue, or black.
Instead, asking “What did you see?” could elicit more truthful answers and go against a cannabis-impaired person’s inclinations to be helpful, even if their answers aren’t exactly spot on.
在寻找有趣的研究时，由于如何与人们的记忆有关，而在大麻的影响下，Tishler表示，这项研究线路迄今为止，可能对刑事司法系统影响不大。
“我不确定它有很多实际影响，”他说。“它进入了法律部分，对我来说是一个非律师，这让我成为巴蒂。”
