1949 CE
The first research about LSD in North America is initiated

In 1949, Dr. Max Rinkel organizes the first LSD research in North America. Controlled experiments are carried out in Massachusetts, which results were later reported at the Annual Meeting of the American Psychiatric Association. Rinkel announced that LSD produced " a transitory psychotic disturbance" in normal subjects, which meant that mental disorders could potentially be studied in a controlled experimental setting.

Dr. Max Rinkel was able to conduct this study thanks to a donation of LSD made by the vice-president of Sandoz, a Swiss multinational pharmaceutical company.
