marijuana intoxication

marijuana intoxication

The constellation of responses to marijuana use, including a subjective "high", which is an altered state of consciousness characterised by: emotional changes (e.g., mild euphoria and relaxation); perceptual alterations, such as time distortion; and intensification of ordinary sensory experiences, such as when eating, watching films, listening to music or engaging in sex. When used in a social setting, the "high" is often accompanied by infectious laughter, talkativeness, and increased sociability. Cognitive changes are usually marked and include impaired short-term memory and loosening of associations, making it difficult to sustain goal-directed mental activity. Over time, this may lead to amotivational syndrome, in which motor skills, reaction time, co-ordination, and skilled psychomotor activity are impaired.
