Comparative subjective effects of seven drugs including lysergic acid diethylamide (LSD-25).

Abstract
"Five Ss were tested on nine occasions under two placebos of tap water and under an average effective dose of 7 drugs--ergometerine (Ergonovine), ethyl alcohol, scopolamine (hyroscine), d-1-brom lysergic acid diethylamide (BOL-148), methamphetamine hydrochloride (Methedrine or Pervitin), lysergic acid monoethylamide (LAE-32), and lysergic acid diethylamide (LSD-25) during 9 different experimental sessions . . … The Ss completed a questionnaire inquiring about their perceptual, physiological and cognitive state before they received the drug or placebo and .5, 2.5 and 4.5 hours after receiving it . . … Although differentiation between 3 lysergic acid derivatives, Ergonovine, LAE-32, and BOL-148, and between alcohol, methamphetamine, and scopolamine was not clear cut, the number of responses to the questionnaire under these drugs was clearly greater than those given under water . . … LSD-25 clearly produced the most frequent and the largest positive responses.
