In the investigation described, the hypothesis was tested that 5-hydroxytryptamine (5HT) acts to reduce the psychological effects of lysergic acid diethylamide (LSD). The method was to inject 5-hydroxytryptophan (5HTP) prior to LSD and to compare the results of psychological tests performed after these injections. Placebo controls were used.
