    Marijuana intoxication impairs memory for feelings. This study found that cannabis use reduced the accuracy of recalling fatigue and other mood states.

    Area of Science:

    • Psychology
    • Neuroscience
    • Pharmacology

    Background:

    • Memory for emotional and affective states is crucial for self-awareness and decision-making.
    • The impact of psychoactive substances, like marijuana, on introspective memory requires further investigation.

    Purpose of the Study:

    • To investigate whether marijuana intoxication affects memory recall for subjective feeling states.
    • To determine if cannabis impairs the accuracy of remembering one's own feelings.

    Main Methods:

    • Participants' feelings were assessed using the Profile of Mood States (POMS) during a period of self-observation.
    • Marijuana was administered either before or during the memory testing phase.
    • Memory accuracy for feeling states was evaluated by comparing recalled feelings to initially recorded feelings.

    Main Results:

    • Marijuana intoxication significantly decreased the accuracy of memory for feelings of fatigue.
    • Cannabis use prior to self-observation impaired recall accuracy across several POMS scales, indicating a broader effect on affective memory.

    Conclusions:

    • Marijuana intoxication demonstrably impairs memory for subjective emotional and feeling states.
    • These findings suggest that cannabis can interfere with accurate self-perception and the recall of internal states.
