Marijuana and memory for feelings.

1. This experiment tested the hypothesis that marijuana intoxication results in an impaired memory for feeling states. 2. Marijuana intoxication during memory testing--that is, after the subjects had observed and recorded their feelings, decreased accuracy of memory for feelings of fatigue, as measured by the Profile on Mood States (POMS). 3. Marijuana given prior to the period of self-observation, impaired accuracy of memory for feelings as measured by several POMS scales.
