1947 CE
The first research about the effects of LSD is published in a Swiss journal

In 1947, the results of a systemic investigation (carried by W.A. Stoll) of the psychological effect produced by LSD are published. The tests conducted during the research involved healthy research subjects as well as schizophrenic patients. Hoffman writes: "The dosages—substantially lower than in my first self-experiment with 0.25 mg LSD tartrate—amounted to only 0.02 to 0.13 mg. The emotional state during the LSD inebriation was here predominantly euphoric, whereas in my experiment the mood was marked by grave side effects resulting from overdosage and, of course, fear of the uncertain outcome."

The article is the first published research about LSD, and appears in the Schweizer Archiv fur Neurologie und Psychiatrie (Swiss Archive for Neurology and Psychiatry). While this publication did not answer the question of therapeutic application of LSD, it gave a scientific description of all the basic features of LSD inebriation.
