Acute effects may include anxiety and panic, impaired attention, and memory (while intoxicated), an increased risk of psychotic symptoms, and possibly an increased risk of accidents if a person drives a motor vehicle while intoxicated.  Short-term cannabis intoxication can hinder the mental processes of organizing and collecting thoughts. This condition is known as temporal disintegration.  Psychotic episodes are well-documented and typically resolve within minutes or hours. There have been few reports of symptoms lasting longer.   Studies have found that cannabis use during adolescence is associated with impairments in memory that persist beyond short-term intoxication.
