The ability of 16 college-educated male subjects to recall from long-term memory a series of common facts was tested during intoxication with marijuana extract calibrated to 0.3 mg/kg delta-9-tetrahydrocannabinol and during placebo conditions. The subjects' ability to assess their memory capabilities was then determined by measuring how certain they were about the accuracy of their recall performance and by having them predict their performance on a subsequent recognition test involving the same recall items. Marijuana had no effect on recall or recognition performance. These results do not support the view that marijuana provides access to facts in long-term storage which are inaccessible during non-intoxication. During both marijuana and placebo conditions, subjects could accurately predict their recognition memory performance. Hence, marijuana did not alter the subjects' ability to accurately assess what information resides in long-term memory even though they did not have complete access to that information.
对16名受过大学教育的男性受试者进行了测试，检测他们在摄入经校准至0.3毫克/千克Δ-9-四氢大麻酚的大麻提取物时以及在安慰剂条件下，从长期记忆中回忆一系列常见事实的能力。然后，通过测量受试者对其回忆表现准确性的确定程度，以及让他们预测自己在涉及相同回忆项目的后续再认测试中的表现，来确定他们评估自己记忆能力的能力。大麻对回忆或再认表现没有影响。这些结果不支持这样的观点，即大麻能让人获取在未中毒时无法获取的长期存储中的事实。在大麻和安慰剂条件下，受试者都能准确预测自己的再认记忆表现。因此，即使受试者无法完全获取长期记忆中的信息，大麻也没有改变他们准确评估长期记忆中存在哪些信息的能力。
