A moderate to low dose of LSD alters time perception in healthy subjects, making them overestimate short audible durations, a pattern also seen in schizophrenia. The study used the same method previously applied to schizophrenic patients, who overestimate such durations more than controls. LSD's capacity to produce schizophrenic-like behavioral changes includes shifts in time sense, with experiences of acceleration, slowing, or even nonexistence of time, though true disorientation is absent.
