Previous studies on lysergic acid diethylamide (LSD-25) and memory suggest that memory impairment becomes evident at doses between 50 and 100 micrograms. At 40 or 50 micrograms, little or no memory impairment was found, but at 100 micrograms, scores were significantly lower on most visual and some auditory tests. One study using 1 microgram per kilogram of body weight also found impairment but only tested memory for unrelated words. The present study aims to determine whether memory for different types of material is differentially affected by LSD-25.
