The numerous examples of ‘drug’ use in prehistory suggests that they may have played an important role in our imaginative development. For example, we now know that the flowers associated with Neanderthal burials had psychoactive properties (Leroi-Gouriian 1984)
The question is not whether drugs were used in prehistory, but rather – to what extent and what for. Prehistoric rock-art and shamanic imagery suggest that humans have been using mind altering substances for thousands of years. It is even suggested that they may have played an evolutionary role in our mental development.
